American Energy Fields, Inc. Enters MOU With American Nuclear Resources LLC for Purchase of Colorado Plateau Mining Properties

American Energy Fields, Inc. is pleased to announce it has finalized a memorandum of understanding to acquire from American Nuclear Resources LLC a significant portfolio of properties Feldspar crusher on the Colorado Plateau in southern Utah and southwestern Colorado.

The portfolio includes past producing properties in the Uravan Mineral Belt, located within 50 miles of Dennison Mines Corp.’s operating White Mesa mill, and within 16 miles of Energy Fuels Inc.’s proposed and newly permitted Pinon Ridge Mill. The Uravan Mineral Belt has produced over 100 million pounds of U3O8 to date. In addition to past production, Yellowcake Mining conducted a drilling program on the Uravan properties in 2008.

The portfolio also includes properties in the past producing Marysvale District, the Henry Mountains District, White Canyon, and the Cottonwood Wash area.

The total portfolio consists of  Copper crusher more than 8,000 acres of unpatented lode mining claims on Bureau of Land Management (“BLM”) land and a Utah State Minerals Lease consisting of over 1,500 acres. As some of the properties have produced uranium in the past, the infrastructure is in place to commence near-term production, contingent on fulfilling permitting requirements.

Company President and CEO, Joshua Bleak, stated, “We are excited to acquire this portfolio of past-producing uranium properties. The Excavator crusher entire Colorado Plateau region has a significant history of uranium production. As past producers, we hope to bring these properties into near-term production, capitalizing on the vicinity to operating and proposed uranium mills.”

Canadian Arrow evaluating nickel production re-start of Timmins deposits

Canadian Arrow Mines, Ltd. (CRO: TSX-V) (the “Company”) reports it has commenced an updated economic review of its wholly owned past producing Alexo and Kelex deposits located 50 km east of Timmins, Ontario. The Company temporarily halted production due to low nickel prices in 2005 to review operating alternatives. Nickel prices have stone crushing plant more than doubled since and attractive operating opportunities have recently developed that further enhance the deposits’ economics.

Between 2004 and 2005 the Company produced 30,138 tonnes of ore averaging 1.93% nickel containing 1.3M lbs of nickel from open pit mining of the Alexo and Kelex zones. At the time the only alternative for the Company was direct shipment of unprocessed ore about 350 km to the Xstrata Nickel Strathcona mill located near Sudbury, Ontario. The Company is currently reviewing economic alternatives to direct shipping that have developed in recent months.

The Alexo property is historically reported to have concrete crusher additionally produced 57,000 tons at 3.6% nickel for a total of 4.5M lbs of contained nickel.

The deposits are classified as Kambalda-style named after similar type-deposits occurring in Western Australia. The Alexo and Kelex deposits are composed of massive to semi-massive nickel sulphide accumulations inhabiting basal embayments along the footwalls of steeply dipping komatiitic ultramafic volcanic flows. The massive, semi-massive sulphides are overlain by stringer, net-textured, blebby and lower grade disseminated sulphide haloes extending upwards and away from the contact. The flows contact with intermediate volcanic country rocks. Other komatiitic hosted nickel sulphide deposits and occurrences in the area include the Redstone, McWatters, Hart, Langmuir 1 and 2, and Texmont.

A total 12,710 metres of drilling in 132 holes were completed in 2004-05 on the rock crusher sulphide mineralization that extends off the known previous workings. The drilling was never completely evaluated for resource potential. An independent qualified consultant has been commissioned to complete NI 43-101 compliant mineral resource estimates on the deposits.

The project remains permitted. Infrastructure including water treatment facilities remain in place as do a closure plan and a closure bond.

President Kim Tyler commented, “The projects provide an opportunity for rapid re-start with low risk and low capital input. The ability to turn-on/turn-off production in response to market conditions would potentially provide cash flow to advance the Company’s flagship Kenbridge nickel-copper project located in Northwestern Ontario. We are expecting to have a NI 43-101 compliant mineral resource estimate completed in the coming weeks which will allow us to evaluate the economics of recommencing production.”

Mechel Announces Launch of Coking Battery #6 at Mechel-Coke

Mechel OAO, a leading Russian mining and steel company, announces the launch of the reconstructed coking battery #6 at Mechel Mining OAO’s subsidiary, Mechel-Coke OOO.

The launch will enable the company to step up production of coke and chemical products and ensure production demands are met, as well as provide an independent supply for sand making machine Mechel’s Chelyabinsk Metallurgical Plant OAO and Southern Urals Nickel Plant OAO.

Due to the reconstruction, the battery nearly tripled its capacity to 470,000 tonnes of coke annually .

The project cost 1.369 billion rubles (48.5 million US dollars*).

The reconstruction involved not only the construction waste recycling aggregate itself but also supplementary equipment. An automated workflow control system was implemented.

Siemens: Expansion of plate production at Dongkuk

In December 2010, Siemens received the Final Acceptance Certificate from Dongkuk Steel Mill Co. Ltd. (Dongkuk) for the new 5-meter-plate mill No. 3.
The mill was built at the company´s Dangjin grinding mill works.
The new mill is capable of producing high-quality plate with thicknesses down to 5 millimeters for applications in the shipbuilding and construction industries.
Siemens were responsible for the complete engineering of all the mechanical and full supply of the Automation equipment.
The Mulpic plate cooling technology
The Dongkuk plate mill comprises a 4-high stand equipped with long stroke hydraulic automatic gauge control capable of producing 11,000 tonnes of rolling force, work-roll shifting functions based on SmartCrown technology and heavy bending, a Mulpic intensive plate cooling section, a hot leveller, and three cooling beds.
The Mulpic accelerated plate cooling technology is specifically designed to produce very high strength plates with good weldability and low alloy content. A shearing line consisting of a crop shear, double side trim shear, slitting shear and divide shear was also part of the grinding mills.
Leading steel producer in Korea
Dongkuk is a leading steel producer in Korea. In the past, Dongkuk and Siemens have completed a series of projects together, with Siemens supplying and modernizing Dongkuk’s plate production facilities and increasing their capacity.
The new raymond mill scheduled production capacity will be 1.5 million metric tons per annum, increasing Dongkuk’s total production capacity of plates for shipbuilding, pipe making and construction to 4 million metric tons per annum.
At the new plant, it will be possible to roll plate with thicknesses of between 5 and 150 millimeters and widths from 900 to 4900 millimeters.The mills are expected to seek further advances, claiming that despite recent hikes they still have little profit margin.
However, many customers have bought forward during the early part of 2011, in anticipation of soaring prices.
Consequently, they are not desperate for material and are in a stronger position to counter the producers’ proposals.
The aforementioned buying patterns, together with the mills’ ongoing below capacity output, have contributed to a tightening of supply, especially for hot rolled coil. Availability of galvanised sheet and coil, on the other hand, is still plentiful.

Future Chinese demand for iron ore

This is according to steel industry consultants MEPS International in their new publication China Steel Insight.
Under pressure to meet government targets to close out-dated polluting capacity by the end of 2010, it appears that Chinese mills did not fully declare their steel production.
saudi arabia crusher estimates that crude steel output in the country was under-reported by as much as 47 million tonnes and production of pig iron by 44 million tonnes.
Consequently production of crude steel in 2010 could have been as high as 674 million tonnes. This compares with a figure of 627 million tonnes published by China’s National Bureau of Statistics.
Some indication of the true scale of steel production is given in the latest production data for 2011, released after the government’s 2010 campaign against out-dated steelmaking capacity ended. This shows steel output early this year running at an annualised rate of production of 706 million tonnes.
This compares with estimates by MEPS that crude steel production in 2010 peaked at an annual rate of 739 million tonnes. The highest annual run rate as stated by China’s National Bureau of Statistics for 2010, was 674 million tonnes. This implies that crude steel production at the beginning of this year, traditionally a period of low output in the Chinese steel industry, was 5% higher than peak rates in 2010. Analysts agree that this is unlikely.
The model Sitop PSU400M in the Sitop modular product range transforms high DC voltages in the especially wide input range from 200 to 900 volts extremely efficiently into a regulated 24 volt DC voltage.
Sitop PSU400M is suitable for drive applications ranging from conventional plant automation through machine tools and textile machines up to wind turbines telsmith crushers.
The power supply range from Siemens Industry Automation Division is being expanded with a DC converter that efficiently transforms voltages in the range of 200 V to 900 V into 24 V.
Wide range of suitability
Sitop PSU400M is suitable both for connection to the DC link circuit of drive systems and for connection to battery networks. The output voltage can be set using a potentiometer to between 24 V and 28.8 V. At 24 V, the converter supplies a rated current of 20 A which, if required, can supply an additional 50 percent extra power over a period of five seconds. This 30 A current enables loads with high starting currents, such as capacitive loads, to be connected without any problems. The yemen crusher for sale new device has a signalling contact for "24 V OK."
The design of PSU 400M
PSU 400M is, like all variants of the Sitop product series, designed for mounting on standard rails. The DC/DC converter is 90 mm wide and can be used at temperatures from minus 25 to plus 70 degrees Celsius. The rugged device in a metal enclosure is designed to withstand high levels of vibration and shock, so it can be mounted close to or directly in the machine. It is also characterized by a high level of electromagnetic compatibility (EMC) which is a particular requirement in the DC link circuits of drives.
The new power supply from Siemens is suitable for a broad range of different applications. PSU400M can be used with frequency converters, for example, to provide an efficient, low-cost power failure concept in which the energy saved in the DC link of the converter is used for the 24 V supply required to coast down the machine in a safe and controlled manner.
An example for use of the shock and vibration proof DC/DC converter with batteries is in controlling the blade angles of wind turbines. For safety reasons, the energy for supplying this so-called pitch controller is supplied independently of the public grid.

Emgold Announces Upcoming 2011 Field Exploration kaolin crusher

Emgold Mining Corporation
Overview

Emgold Mining Corporation (“Emgold” or the “Company”) announces its upcoming 2011 field exploration plans for its Stewart Property, kaolin crusher B.C. The Stewart Property is located in the Nelson mining district, near Salmo, B.C and is an attractive poly-metallic exploration property. It contains a variety of styles and types of mineralization, with targets identified in different areas within the property. Targets include the Stewart Moly Zone, the Arrow Tungsten Zone, the Craigtown Gold Zone, and the Free Silver Zone.

In December 2010, Emgold raised CDN$500,000 in flow through funding for exploration work at Stewart in 2011. The Company plans to use these funds to continue drilling of the Stewart Moly Zone, with a goal of ultimately defining a NI 43-101 compliant molybdenum resource. Additional work may be done to further explore the Craigtown Gold Zone, to enhance work on previously identified gold prospects. Currently, the Company is completing permitting activities to allow this exploration work to occur in the summer of 2011. A computer model of the molybdenum deposit is being developed to plan the 2011 exploration drilling program. The model is being developed using Surpac software, to allow better identification of the best location of infill drill holes needed to determine the size and shape of the mineral deposit. Subsequently, details of the exploration program will be finalized and diamond drilling will commence.

Stewart Moly Zone

The Stewart Property has been examined by 14 different companies since 1942 for tungsten, copper, molybdenum, gold and silver. Historic exploration of the Stewart Moly Zone has included geological mapping, soil and rock geochemistry, geophysics, trenching and drilling. The most extensive of those historic programs were conducted by Shell Canada Resources in 1980-1981 and Selco Inc. in 1983. The two companies were searching primarily for molybdenum and drilled 23 holes in the area. In 1981, Shell delineated a narrow, steep dipping podiform breccia resource containing and estimated 204,000 tonnes at a grade of 0.37% MoS2 (0.22% Mo). These historic drilling results cannot be verified for the purposes of National Instrument 43-101 (NI 43-101) and therefore this information is not NI 43-101 compliant. This information, however, is a useful guide for future exploration by the Company’s geologists.

Emgold acquired the Stewart property in 2001 and continued evaluation of the Stewart Moly Zone in 2005 and 2007. Geochemical sampling, geophysics, trenching, and drilling programs were completed to check historic work and further assess the strong molybdenum mineralization in the area. The Company drilled eight holes in the area, two of which were twin holes adjacent to historic drilling

Craigtown Gold Zone

The Craigtown Gold Zone is an early stage exploration target identified by previous exploration activity. Several companies conducted gold exploration programs in this area from 1989 through 2001. Initial exploration included soil and rock geochemistry, induced polarization, VLF-EM and ground magnetic geophysical surveys, trenching and diamond drilling. Surface exploration indicated the presence of gold mineralization trending southward toward the historic Arlington Mine, located just south of the Stewart claim block. This mineralization occurred as two separate low grade gold anomalies, plus a zinc-gold anomaly, in narrow veins within volcanic tuffs and diorite.

Cameco Corporation conducted trenching (in 1992) and gypsum crusher follow-up drilling (in 1993) at Craigtown and found low-grade gold in the volcanic and dioritic rocks near a feldspar porphyry contact. They interpreted the control on gold mineralization to be the intrusive-country rock contact. Cameco drilled four holes totaling 448.8 meters to test a soil anomaly identified the previous year. The results of the drilling showed anomalous gold values typically up to 200 ppb (0.005 opt) over 1 to 2 meter sample lengths. The highest gold value came from hole DEN-93-4, which assayed 24,854 ppb (0.725 opt) from a one meter interval in a quartz-calcite vein. A check assay also had similar results (19,800 ppb, or 0.578 opt). These historic drilling results cannot be verified for the purposes of National Instrument 43-101 (NI 43-101) and therefore this information is not NI 43-101 compliant. It is, however, a useful guide for future exploration.

Emgold acquired the Stewart property in 2001 and completed soil sampling of the Craigtown area that same year. Elevated gold-in-soil values of up to 84 ppb (0.002 opt) were found in the North Craigtown anomaly along with weaker values of 43 ppb (0.001 opt) in the South. In addition, a zinc soil anomaly with values up to 681 ppm was found.

In 2004 Emgold conducted rock and soil geochemical sampling and drilled two holes in the vicinity of the Craigtown gold anomaly. The Company found weak anomalous gold-copper mineralization, with gold values in the 0.26 to 0.43 grams per ton (0.007 to 0.012 opt) range. Exploration may include geochemical sampling, trenching, and possibly limited drilling of the Craigtown gold anomaly, depending on funds available.

Stewart Summary

Upon completion of computer modeling, layout of the drill program, and receipt of necessary permits, Emgold plans to commence exploration activity on the Stewart Property in the summer of 2011.

David Watkinson, President and CEO of Emgold stated, “The Stewart Property represents a highly prospective exploration property with a variety of exciting targets. Emgold’s current strategy is to complete additional diamond drilling with the goal of ultimately defining an NI 43-101 compliant moly resource in the Stewart Moly Zone. This will add value to the Company for our shareholders and improve the value of the property. Given the current high price of gold, we are also interested in further exploring the Craigtown Gold Zone which, while early stage, shows potential for a significant discovery.”

Additional Information on Emgold’s Rozan Property, B.C.

Emgold quartz ore crusher also has a second exploration property located in B.C., southwest of Nelson, called the Rozan Property. It is currently under a lease and option to purchase agreement by Valterra Resource Corporation. Valterra recently made its 2011 property payment and has commitments to make CDN $250,000 in cumulative work expenditures on the property in 2011. Valterra controls over 11,000 hectares of exploration properties in B.C., including the Star, Toughnut, and Rozan properties.

Information in this news release that is of a scientific or technical nature was reviewed by Perry Grunenberg, P.Geo, an independent consultant to the Company. He is a Qualified Person as defined in National Instrument 43-101.

Compass Gold Mining Exploration

Compass Gold Corporation provides the following update regarding its exploration activities in Mali, West Africa relating to four exploration gold research licenses held by Africa Mining SARL (“Africa Mining”) in which Compass is currently earning a 51% interest.

Compass recently gold mining equipment completed a C$2,000,000 non-brokered private placement. These funds will be used to complete the Phase II Exploration Program including initiating a major high-resolution airborne magnetic and radiometric survey over its licenses and drill targets.

HIGHLIGHTS:

– Major high-resolution aeromagnetic survey over all four licenses to
commence in March 2011.
– Mobilization of drilling equipment commences.

Details as follows:

1. MAJOR HIGH RESOLUTION AIRBORNE MAGNETIC AND RADIOMETRIC SURVEY TO
COMMENCE

The Phase II exploration program will be strengthened by the dolomite crusher commencement, on March 21, 2011, of a major high-resolution airborne magnetic and radiometric survey (“Survey”) over all four licenses.

The Survey has been brought forward from Phase III, to provide additional information for the interpretation of results of a scout drilling program, and to assist in planning Phase III Exploration Program.

Aeroquest (Aust) Pty. Ltd. has been contracted to undertake the Survey. The Survey covers all four licenses (Yanfolila, Kolondieba, Dandoko and Solabougouda) comprises 4,834 line km and is being flown on a East-West orientation at 200m line spacing with a nominal ground clearance of 70m. Areas with identified gold targets on the Yanfolila and Dandoko licenses will be flown at tighter 50m line spacing. It is expected that the entire Survey will be completed within 4 weeks.

The results from the Survey will assist in guiding the planned scout-drilling program and in identifying additional targets. Part of the drill program will be undertaken concurrent with the Survey to maximize results from all activities on the known gold targets.

2. MOBILZATION OF DRILLING EQUIPMENT COMMENCES

Africa Mining confirms that concrete crusher has commenced the mobilization of drill equipment for the Phase II 5,400m RC (reverse circulation) drill program, which will be expanded subject to results.

As previously announced, the aim of the initial drill program is to intersect gold mineralization at depth, in hard rock. The program will focus on drilling the following initial targets:

– Solona and Yanfolila gold anomalies on the Yanfolila license with
drilling to start before the end of March 2011; and
– Disse target on the Dandoko license with drilling to start in April
2011.

Oakajee denies Australian report of cost blow out

Murchison Metals has slammed a report about Oakajee Port and Rail (OPR) today in The Australian, which it was unsubstantiated and speculative.
The Australian reported that the capital cost of the Oakajee port and rail project has “ballooned from $4.4 billion to as much as $6.7 billion, potentially crippling attempts by China crusher machine and Japan’s Mitsubishi to build the critical infrastructure.”
The publication claims it has received confidential letters and financial documents which show Mitsubishi now believes the Jack Hills magnetite project in Western Australia, will cost $3.9 billion.
They also apparently show that Murchison and Mitsubishi believe meeting tough new deadlines imposed on the Oakajee project is “highly unlikely” and that they told WA Premier Colin Barnett it will be “extremely difficult” to finalise key implementation agreements by 31 March.
But Murchison, which owns half of the Oakajee project, have released a statement denying the claims.
“Murchison advises that any reference to capital estimates prior to completion of the bankable feasibility studies (BFS) for the project remains premature and entirely speculative.
“The BFS, which highway crushing plant will include definitive cost estimates, remains on track for completion in the June quarter 2011.”
Murchison’s estimates for the total capital cost for Oakajee last year were $4.4 billion, including a $565 million contribution from state and federal governments, to fund the common-user infrastructure port.
The Australian claims a document named “Mitsubishi Development” estimates the project cost is now $6.7 billion and includes about $930 for the common user infrastructure.
The Australian has referenced “a source” who claims Mitsubishi made a mistake with the sums for the project and the $930 million should have been included, bringing the actual cost of the project to near $5.8 billion.
Murchison said it is not the only company dealing with changing costs in the current financial climate.
“Cost escalation is clearly an issue affecting all major projects in Western Australia in the current environment, and it is therefore likely that there will be some increase from the capital estimates contained in OPR’s draft BFS report, that were released to the ASX in March 2010,” the statement said.
“However, Murchison advises that the budget and engineering study completed for OPR in late November 2010 as part of the BFS process resulted in an indicative capital cost for the Oakajee port and rail project of approximately $5.239 billion, exclusive of all Common User Infrastructure.”
The Australian report said there has been speculation in recent weeks that design changes to Oakajee and the changes in costs of steel and equipment in the resource sector would increase the project budget beyond $6 billion.
But Murchison states the estimates for the Oakajee are ongoing.
“Murchison advises that this estimate remains preliminary and indicative only and is subject to ongoing review, optimisation and value engineering to identify potential cost refinements and savings prior to final signoff by Murchison and Mitsubishi Development Pty Ltd.”
The statement also notes that this month the WA government agreed to extend the deadline for completion of the Implementation agreements for the Oakajee project until 31 December this year.
Earlier this month construction waste recycling Western Australia’s Opposition state development spokesperson, Mark McGowan, accused Western Australian Premier Colin Barnett of acting like a dictator on the Oakajee project and urged him to grant the port and rail extension for the port.
A spokesperson told Australian Mining that if all approvals are granted, Oakajee expects to commence early work such as roads at the end of this year, with construction continuing until 2014-15 and first shipments may be possible by 2015.

The formation of coal

After the dead plants on land, the residues exposed to the surface, the oxygen-rich conditions, through wind and rain,
Will dry rot. After dry rot, and some substances in the atmosphere is going to go into a gas, and the rest is just hard oxide mineral complex
Quality, this can not be turned into coal. But when a large number of higher plant debris in the lake covered by water, debris and water so that plants
Air separation, so they can not oxidation, hydrolysis and then the biochemical role of anaerobic bacteria, most plant debris
Points lose their structure, becoming black material of brown water, this dark brown material called "peat", and low
And other plant debris becomes sapropel. We call this process is called the stage of peat, which is changing the initial stage of coal beneficiation .
After the phase of peat, over time, decreasing the crust, the peat layer to the sediment carried by water and other objects
Quality of the coverage, and gradually thickening, resulting in some downward pressure. Under the influence of pressure and temperature, along with the peat water ,coal grinding mill.
Reduced carbon content began to increase and become brown. When more and more above the sediment thickness, and as the depth increases, the pressure and temperature was correspondingly increased, making the gradual increase in the degree of carbonization, moisture, volatile matter gradually reduce the carbon content increases, the proportion increased, gloss increased deterioration into a variety of bituminous coal. When the pressure and temperature further increases, will be further carbonization of bituminous coal into anthracite continued deterioration of this phase is called coalification stage.
Ecological Protection
1. Mine feasibility study and design should be predicted by surface subsidence caused by underground mining the scope, extent and the corresponding time.
2. Mine design should actively adopt new technology to reduce surface subsidence.
3. Mine protection design must be based on relevant national regulations on environmental protection and land reclamation, in accordance with local planning and the collapse of the specific conditions corresponding comprehensive improvement measures.
4. Mine industrial sites must be green, green should meet the practical, economic, and aesthetic principles.
5 demonstrates the original mine design should be based on soil erosion, development of water conservation measures.
6. Environment Agency set up and special investment
7. Mine environmental management agency should be set, with 1 to 5 full-time management and monitoring of staff, responsible for the organization, implementation, supervision and monitoring of the mine environmental protection concrete crushing equipment.
8. Mine should be equipped with environmental monitoring equipment for routine monitoring.
9. Where are the required pollution control and environmental protection installations, equipment, monitoring means and engineering facilities and other investments belong to the investment in environmental protection. Where the mine must have transferred production of the environmental protection investment, construction investment should be included in mine.

working principle of cement mill

Flotation flotation process flotation separation of minerals to achieve the basic equipment. Flotation (flotation) of the driving rotation, centrifugal vacuum air and water enough to form a mixture of mud, while inhaling, a triangle on behalf of the impeller motor drive, and drug mixing mud, foam and perfect, so the above float to the surface, and mineral mud salinity adhesive foam bubbles. Control gate height, control surfaces, so this is very useful foam scratch. The device is a non-ferrous metals such as copper, zinc, lead (for separation, nickel, gold order), ferrous metals, precious metals, non-metallic minerals (such as: coal, fluorite, talc sort), chemical raw materials, recovery of useful minerals.

Cement Mill should have the following basic requirements:
First of all, good ventilation flotation pulp must ensure that sufficient air intake volume (about flotation machine is the external pressure, the air compressor to the air) and far in the tank may be scattered. Because the smaller the air more evenly distributed, mineral particles and air bubbles in contact with the opportunity to more flotation efficiency higher.
According to the above requirements, no matter what kind of flotation machine has several basic components as follows: (1) tanks, which discharge into the hole and the porous materials of the plasma, and adjust the door open pit mineral processing equipment; (2) inflatable device ; (3) mixing device; (4) mineralization of foam discharge devices.
Zhengzhou Winbond machinery flotation machine, the device has the following characteristics: inspiratory capacity, low power consumption. Both inspiratory per slot, the triple function of grout and flotation, since the flotation circuit without any auxiliary equipment,the staffing levels, to facilitate the process of change.
Reasonable period of pulp can to minimize the precipitation of coarse sand. Loose control device, easy to adjust. Impeller blade and backward curved up and down. Pulp production cycle under the leaves, leaf pulp circulation and production.
Slurry into cement ball mill the flotation tank and pharmaceutical work in the first mixing chamber, the impeller rotation, the formation of negative pressure in the wheel cavity, the lower impeller and suction aspiration into the mixed zone at the bottom of the mud tank, but also makes the air along the guide sleeve into the mix, mud of the air, mixing chemicals in the air here. The role of the centrifugal impeller, a mixture of mud into the mineralized zone, the formation of bubbles and was crushed, full access to coal particles, the formation of mineralization in the stator and turbulent foam tank evenly.

The role of coal and the mining process

The role of coal
Extensive use of coal, can be summed up in accordance with its intended use two main purposes: (1) thermal coal (2) of coking coal.
The main purpose of thermal coal are:
1) Power generation coal: China about 1 / 3 of the coal used for power generation, coal generation is the current average standard coal 370g / (kW · h) or so. Power plants use the heat value of coal, the heat energy into electrical energy.
2) steam coal: coal-fired power accounts for about 2% of the average coal steam boiler indicators 100kg / (ton km) or so.
3) Building Materials coal: about power more than l0% of coal to cement the largest amount of coal, followed by glass, brick, tile and so on.
4) Coal Mobile Crusher, general industrial steam coal: In addition to large-scale thermal power plants and heating boilers, in general, corporate and industrial boiler heating model range, the number of large and dispersed, coal accounts for about 30% of steam coal, Shanxi Coal Talent Network.
5) Life of coal: the larger the number of coal of life, about 20% of fuel coal.
6) The metallurgical thermal coal: steam coal for metallurgy sintering and blast furnace is mainly used anthracite, the amount of less than 1% of coal power.
(2) of coking coal
Although China is rich in coal resources, but relatively few resources of coking coal, coking coal reserves of only 27.65% of total coal reserves.
Class includes coking coal gas coal (accounting for 13.75%), fat (accounting for 3.53%), coking coal (accounting for 5.81%), lean (accounting for 4.01%), others are not sub-grade coal (0.55%); non- Class includes anthracite coking coal (accounting for 10.93%), lean coal (accounting for 5.55%), weak base coal (accounting for 1.74%), non-payment of coal (13.8%), long-flame coal (accounting for 12.52%), brown coal (accounting for 12.76 %), natural coke (accounting for 0.19%), not sub-grade coal (accounting for 13.80%) and grades of coal unclear (accounting for 1.06%).
The main purpose is refining coking coal coke, coke from the coking coal or mixed coal high temperature smelting from the general about 1.3 tonnes of coking coal to coke smelting a ton. Coke used for steel making, is a major producer of steel and other raw materials industry, steel industry has been hailed as the "basic food."
China is the largest producer of coke, the coke market is the world's major exporters. In 2003, global coke production was 3.9 million tons, China's coke output reached 178 million tons, accounting for 46% of global output.

Coal mining process
Gangue emissions: emissions from the largest coal production of solid waste, industrial solid waste is produced in China and the accumulation of the largest volume of solid waste output is generally about 10% of coal production. China's annual emissions of coal gangue about 1.5 billion to 2.0 billion tons. The end of 2002, the country earned about 3.4 billion tons of coal gangue, covering 26,000 hectares, is the output of industrial solid waste and accumulated in the cumulative amount of the largest solid waste. In 2004, the amount of gangue comprehensive utilization of 1.35 million tons, 54% utilization.
Mine water discharge: in mine construction and production process, various types of raw water will enter the tunnel through different ways and face, in order to ensure mine safety, to prevent water damage occurs, the need to discharge mine water inflow. According to incomplete statistics, in the mining process, the 2004 national coal mine water discharge about 30 billion m³, the average discharge per ton of coal is about 2m ³. Resource utilization accounted for only 22%.
, Driving the compressor;
Mine gas drainage and ventilation: in the former coal mining and gas exploration in the gas drainage is an important measure to ensure mine safety. But the drainage of the gas into the atmosphere, will have a strong greenhouse effect, greenhouse gas methane contained 20 times larger than carbon dioxide. Another mine in the production process, the underground tunnel will need hundreds of thousands or even every second millions of cubic meters of air, which is mainly done through the mine ventilation, mine ventilation also contain gas, and there are a lot of dust. According to estimates of the evaluation in recent years, the national coal seam gas resource of 3 × 106 Mm ³. In 2002 China's key coal seam gas production capacity of 9773.37Mm ³, which use gas capacity of 517.49 Mm ³, utilization rate of about 5%.
Traditional coal mining neglecting other symbiotic and associated minerals mining, processing, utilization, resulting in waste of resources. China coal co, 20 kinds of minerals associated with, the vast majority did not use the free storage of discarded other minerals can also cause environmental pollution and damage to ecological environment.

Basic skills in concrete pouring

Basic skills in concrete pouring
Concrete recycling is a key process, the quality of its concrete, structural integrity have a direct impact. Therefore, the requirements of pouring the concrete should be dense, can be full of templates, steel and embedded parts to ensure the correct position, a good combination of old and new concrete after the concrete surface smooth and form removal, clean, accurate size and so on.
One. Three basic skills placement
Concrete construction, concrete conveying a different way, with a variety of templates, but the final forming of concrete quality of the decision by the pouring process.
1. The whole placing
Is to maintain the overall pouring concrete layer, the overall segment. Such as frame building, each of the columns, walls, beams, floor, staircase, balcony ... ... and so form a whole together. Due to temperature, geological and other reasons, the structure of the joints, settlement, sub-seismic construction joints, etc.; layered construction; each segment, all the components within the layer, is a whole. A section of the pouring of concrete layer should be a complete, without leaving a construction joint.
2. After the first addition, the first away in recent
After the first addition is a column, wall, beam placement procedures. Pouring should be pouring outside corner of the columns and walls, and then pouring the external columns and walls in other parts, and finally pouring the internal columns, walls and beams. Its role is to make the wall corner to corner posts and chromium crusher correct positioning of the template to ensure that building form.
After the first distant past, is the floor, floor or base plate of the concrete pouring process. In accordance with the direction of incoming concrete, first for the far post for the past. The laying of concrete slab to facilitate transport to facilitate feeding; easy to tamper and closing surface; if feed too much, but also easy to be returned.
3. Mortar first
The fabric into the mold before the template layer of concrete mortar with the strength of the same quality, so that there is adequate or surplus at the bottom of the mortar, concrete base to ensure full, angular Founder, smooth appearance.
Pouring floor or ground floor before the template side next to the thin layer of thickness of 15mm, extension of about 600mm, the width of the same face of the mortar, concrete placing will be lower mold.
Beam placement before the end of the beam covered with a thickness of 15mm, length 600mm mortar for the end of pulp.
II. Key concerns concrete pouring
1. Time interval, the initial setting and final setting time
Cement in concrete with water to completely harden after mixing with 4 stages: the initial response phase, telogen, setting and hardening of the period. The length of time required, because different varieties of cement. The initial reaction of about 30min, resting period of about 120min, only the concrete period of time with elastic, plastic and viscous rheology.
2. Layer thickness
Layer thickness is 200mm or so, before the layer of depth when tamping 20 ~ 50mm.
3. Pour off the high degree of
Pour off the high degree of freedom should not exceed 2m. Otherwise, string tube should be used, or chute, the concrete tube or chute along the string whereabouts to avoid concrete segregation.
4. Mortar bottom
Before pouring the vertical structure, the bottom should be filled with 50 ~ 100mm thick cement concrete the same ingredients.
5. Die stability
In the cement mill process, should always observe the template, frame, steel, embedded parts, and set aside the case of holes, and when there deformation, the shift should take timely measures to deal with.
III. Construction joints of the lien and precautions
As concrete pouring non-consecutive time, the two poured to form a joint, this joint is the construction joint.
1. Set construction joints
Location of construction joints shall meet the design requirements and construction technology programs. The location of construction joints should remain in the structure of the shear stress is small and easy construction of the site.
2. Treatment of construction joints
1) The initial setting of concrete, you can not continue pouring immediately above the new concrete, or new concrete in the vibrator, it will damage the already clotted internal structure of concrete and affect the combination between old and new concrete. To the compressive strength of concrete has been poured to 1.2N/mm? Later allowed to continue pouring concrete.
2) before pouring, to the debris at the construction joints, remove loose gravel, etc., and cutting hair, washed with water, not water to fully wet.
3) prior to pouring concrete, advised in a layer of construction joints and concrete grout or cement mortar equal to the composition and thickness of about 15 ~ 15mm. First tamping concrete mortar and the original, and then pouring concrete.
4) tamping at the construction joints to be detailed and should make new and old concrete into a whole and enhance moisture conservation.

Mini excavator for the broken machine industry open up new markets

Excavator Hammer led the industry in a variety of Hammer's sales, although so far no one can say how many sales per year worldwide breaker, but it at 4 million to 4.5 million units is not too much between, as in So far the demolition site, we often see the hydraulic hammer and feldspar crusher.
Both micro and large excavators excavator, which led to a variety of hammers sales. Hydraulic breaker is a key tool for dismantling industry. Lindsay Gale Hammer reported the development of industry trends and the latest listing of products. No one can tell the world how many were sold each year in the end all kinds of hammers, but the "International Demolition and Recycling" magazine that the figure of 4 million to between 4.5 million units is not too much. Although Hammer is not used in the removal of most of the industry, but there is no doubt that today saw the dismantling of the most common site of non-hydraulic hammer tool is none other than.
Hydraulic hammer is still the major markets in Europe, North America and the Middle East, followed by the Far East, the market looks good. Atlas Copco Construction Tools Company head of the U.S. Department Peter Bigwood told the "Demolition and Recycling International" magazine: "In the past two years, the industry has maintained double-digit market growth, the It seems 2006 will be a high double-digit, and this growth is overall growth of all types of breakers are on the rise. To meet this demand, we have in the last 3 years to increase production capacity every year. "
Korean Hanwoo company in favor of this view. It reported sales in Europe and North America accounted for 50% of total sales the excavator crusher, other markets are also growing since 2004, such as Turkey, Spain and Qatar. In fact, Spain is Hanwoo the company since 2005, the second largest market. This is the Spanish market, separated from the great demand for excavators, mini excavators, or whether it is large excavators, which led to the sale of a variety of hammers.
MSB is also a large Korean manufacturer of the breaker, is very active in the export business, it is also to Europe, North America and the Middle East as its main market. To this end, Hanwoo is stepping up efforts to improve some of the new development's share of the market, especially in the former Warsaw Pact country markets and Indian markets, since these markets are expected to fast economic growth.
When most of the large hammer into the quarrying industry at the same time, but the dismantling of small and medium sized hammer dug a vat of gold industry. Here, Hammer complete specifications, suitable for a hydraulic system and power output of all types of construction machinery.
Of course, there is a broken design requirements, including low-noise may be the most important design requirements, because the whole industry is going through a "green" revolution, the result is "quiet" products more and more popular, many manufacturers have mute and unmute can provide products for customers. In fact, so popular in quiet, sharp and fierce in the eastern part of the company product manager for Southern Europe Teemu Teelahti recent "Demolition and Recycling International" magazine, said he had a premonition that the future may have only developed silent type products.
Reduce the vibration is another major design requirements, but there are two aspects of this requirement. The first is the use of hand tools to reduce arm and body workers, the harmful effects of vibration. This means that construction trade associations to continue to work looking for these machines to replace hand tools, the result is a hammer to install a compact substantial growth in demand for construction machinery such as skid steer and mini-excavators and other machinery. These machines light and small, can be used indoors, as the broken machinery has opened up a broad market.
Secondly, it also has a drawback, because another machine vibration regulations limit the damage to the operator. This means that now the manufacturers of breaker should think of ways to minimize the vibration of the hammer.
Compact Power
For removal of compact construction machinery industry users for what appeared on the market of new products?
Caterpillar D Series Hammer added H35Ds, H55Ds and H65Ds 3 types of products, the installation of chassis specifications breaker extended to 1.1 ~ 70t.

Mobile crushing station to reproduce the world to speed up the construction waste disposal beautiful country

With urbanization, the production of this construction waste is an inevitable phenomenon, an expert he also joked that if we do not impose such a construction waste recycling, then the beautiful country landscape will become garbage. Construction waste is construction, the construction unit or individual team all types of buildings, structures, pipe network, the construction, laying or removal, repair was produced by the process of construction waste, abandoned soil, materials, Yuni and other waste. However, these construction waste, the vast majority of untreated, open dumps or landfill, a considerable amount of land acquisition fees, garbage fees, construction expenses, while, removal and stacking process Yisa and dust, fly ash sand and other issues has caused serious environmental pollution. Human survival and development, resource utilization and environmental protection is particularly important, construction waste recycling technology, received wide attention. China's current construction waste recycling technology has a certain basis,granite countertop,whether it is applied laboratory research or the market has a certain outcome. Not only is construction waste, we are promoting all the solid waste disposal it is certainly the best resource, not only because of the construction waste problem could become garbage, you refuse treatment may also be ordered if not now, there will be garbage Besieged, and so the phenomenon, for all solid waste, the best way to dispose of all resources. Are engaged in the industry who said that this construction waste is money, money and attention to students, unable to have money nobody, do you think is the reason for this? Now the current solid waste resources, In fact we state without a unified management system, are relying on market-oriented operation, is one of the market is certainly part of the available profit or a large part of the recovery will be better people, but a small part of your profit, or part is not available, you have no obligation, to how to dispose of it, certainly not to manage his people, and now the market is certainly doing this normal, the trend of the market economy, gold mining equipment sale we do not have to bind the relevant management systems He, no profit and no one will do that piece. Many of the waste of construction waste by sorting, removing, or crushed, most of the re-use as renewable resources such as: scrap steel, scrap wire, scrap wire, and various accessories, such as scrap metal by sorting, concentration, re-melted again after processing into a variety of steel products; waste timber bamboo can be used to make artificial wood; brick, stone, concrete and other waste by grinding, you can substitute of sand for mortar, plaster mortar, playing concrete bedding, etc., can also be used to make blocks, shop road bricks, tiles and other building materials lattice. More concentrated as construction waste piling up, the venue is limited, and traffic is not very easy, you need to deal with outstanding equipment. Shanghai Zenith R & D of mobile crushing plant, specialized for crushing of construction waste, from the rough broken, broken, broken bits, and many processed, refined for the metallurgical, chemical, building materials, utilities often need to move the material processing operations, especially the use of on the highway, railway, water and electricity engineering job mobility stone; mobile crushing plant crushing site is small, fully meet the needs of the scene, and even processing of raw materials according to the type, size and material requirements of different products using a variety of configurations.
