Global iron ore supply is still rising in the second half of the year

China's Baoshan Iron & Steel in charge of a senior, said on Thursday that the global demand for iron ore will not grow in the second half of 2012 and may even decline compared with the first half, while the supply is still rising.

Baosteel is China's largest listed steel enterprises, the person in charge of procurement operations Chang Tien wave in a industry meeting, said the global seaborne iron ore supply in the second half of this year compared with the first half, an increase of more than 50 million tons.

Further decline in demand, coupled with new mine supply iron ore price has dropped to three-year lows, may fall further in the coming months, the threat of Rio Tinto and Vale do Rio Doce and other large mining enterprises profitable.

"With industrialization, urbanization and infrastructure investment pace of slowdown in Chinese steel demand growth rate has decreased steadily," said Chang Tien wave.

2011-2015 the average annual growth rate of China's steel demand is estimated at 4.2%, but if we can achieve this increase is "Chang Tien wave that.

China's crude steel production in January-July year-on-year increased by only 2.1%, to 419.5 million tons in the same period last year representing an increase of 10.3%.

Chang Tien Bo said, China's steel production will reach 700 million tons in the next 15 years the limit, and then began to decline.

The Australian mineral Feast end to finish at the introduction of mining giant contraction strategy

Australian Resources and Energy Minister Martin Ferguson has said that the mining boom has ended. The remarks immediately triggered several senior officials, including Prime Minister Gillard rebuttal, the latter insisted that far from the end of the mining boom will continue to support Australia's sustained economic growth.

As a pretext for the head, scattered around the mining prospects remarks fierce collision is the evolution of the long and short view, a reflection of the Australian mining complex variables. Despite excessive sing empty Mining may be too hasty, short factors affecting the mining industry would still be worth to think calmly.

The mining magnates introduced contraction strategy
Recently, BHP Billiton, Shell, Woodside mining giant has announced the postponement of Australia iron ore, natural gas project, involving the amount of investment so far has exceeded 68 billion Australian dollars (U.S. $ 70.4 billion). The direct cause of action in a series of contraction is the uncertainty of market trends.

Affected by the European debt crisis, slowing growth of emerging economies and other factors, the main iron ore price of about $ 180 per ton from the same period last year shock down to below $ 100 a tonne, a record low since December 2009.

Pushing Hands introduction of mining giant contraction strategy much more than lower prices. Exchange rates, tax rates, finance, and industry profit distribution structure factors can not be ignored. CLSA analyst Ian Loper said iron ore prices fell to $ 60 per ton in 2008, but then the Australian dollar against the U.S. dollar exchange rate is only 1 to 0.6, the cost is relatively low. In recent years, however, the exchange rate of the Australian dollar against the U.S. dollar exceeded 1.1 high and stable at a ratio of 0.93 or more in the past year. This means that the market price is lower, the profit margin of the miners and even less than the outbreak of the global financial crisis.

BHP Billiton CEO Marius Kloppers pointed out that over the past 10 years, the Australian mining development costs in U.S. dollar terms increased sevenfold, half of the cost increase is directly due to the Australian dollar soaring.

Australian government efforts to promote the carbon tax and mineral resources rent tax reform. Taxes to improve together with the high Australian dollar and other negative factors, will significantly increase the cost of mining development.

The research report released by the Minerals Council of Australia, Australian thermal coal cost per tonne of new capacity within the past five years rose three times, so that the relevant feasibility of the project into doubt. Compared to West Africa, 75% above the cost of iron ore mining in Australia.

In addition, some small and medium-sized mining companies must also focus on financing costs.

Disparity unfair distribution of profits of the upstream and downstream
In addition to the above factors, the Australian mining more fundamental problem is that the status quo of the current industry upstream and downstream disparity unfair distribution of profits.

For example, iron ore, according to industry sources, one ton of iron ore in Western Australia offshore cost less than $ 60, while the offshore market in recent years, the average price was as high as about $ 160, and for many years maintained a double-digit increase. Many Chinese steel enterprises but has incurred losses in miners earn pours. By the shrinking demand for steel, Steel Association member companies, losses in the first half of this year more than one-third of August, expanded to more than 80% loss. China Steel Association said China's steel industry is only 1.68 yuan (about 0.26 U.S. dollars) per production of 1 ton of steel profits.

As an important raw material base of the China Iron and Steel Industry, Western Australia more than 70% of the iron ore supply the Chinese market. In this regard, one wonders, in industry downstream face of massive industry-wide loss situation, the mining the feast what can enjoy long?

Analysts pointed out that the view of some developing countries, urbanization, industrialization process has yet to be completed, and the Australian mining investment accumulated stock of up to 270 billion Australian dollars (U.S. $ 279.6 billion), mining will continue to support the economic growth of Australia. In addition, since the financial crisis, the U.S. policy of quantitative easing fueled commodity markets may still push up the market price if the authorities to release a new round of quantitative easing.

However, if future short factors continued to exert influence each other, inevitably promote the current mining boom downhill.

Australia's central bank recently said that mining investment is expected to peak will be reached in the 2013-2014 fiscal year, and then after years of downlink non-resource sector investment will appear accordingly uplink. This may help to alleviate the current plight of Australia's two-speed economy ".

Impact crusher operation works and disadvantages

Impact crusher procedure works plus the strengths and disadvantages

Impact Crusher is really a extremely powerful new crushing equipment.

The ore from your feed port to your entry, and slid down along the sieve, the ore around the sieve during the dropping system, i.e. the high-speed rotation around the rotor carbide hammerhead crushed within a tangential course, along with a incredibly high speed traveling initial a counterattack board, ore continue to get damaged, counter plate carried the ore strike collide with each other ores thrown again driving the rotor, so during the initial crushing chamber ore was crushed by recurring shocks. Some ore damaged during the initial crushing chamber into a specified dimension, after a counterattack the gap amongst the plate plus the rotor row to your next crushing chamber, continue to get recurring strikes right until the smaller particle dimension right after row of ore from your bottom with the crusher discharge port .

Crusher from your earlier mentioned, would be the impression theory crushed ore, is represented because of the following two formulas:

Ore kinetic energy obtained: E = 1/2MV2

Ore by impression:

F = M (V2-V1) / T

Where M - the standard of the material to get damaged, kg;

V - the rotor peripheral velocity, m / sec;

V2 - the components block is overcome speed, m / sec;

V1 - components block was versus the speed, m / sec;

T - the function of time, in seconds.

Is often observed from your earlier mentioned equation, inversely proportional to your the counterattack force with all the duration of action, and lump ore is proportional to your acceleration suffered materials blocks the kinetic energy plus the sq. with the speed with the rotor motion and high quality of components proportional to your products.

The principal benefit of the impact crusher:

one) basic framework, modest dimension, light-weight excess weight, substantial ability, small production prices.

two) ore along the joint aircraft damaged, so less electricity usage, high efficiency.

3) damaged than substantial, around forty, so you can simplify the procedure damaged, could make the three-stage crushing into two sections or even a damaged, reducing the price of the concentrator equipment.

four) owning a selective crushing outcome, plus the crushed products of fairly uniform particle dimension, form nearly all the cube.

The largest drawback with the impact crusher, hammer and counterattack plate have on a lot quicker.

vertical shaft impact crusher

The vertical shaft impression crusher, often called the Sand, is really a combo with the genuine circumstance of domestic sand making production developed productive crushing equipment for domestic and global major levels. It's broadly made use of within a a number of rock, abrasive, refractories, cement clinker, quartz, iron ore, concrete aggregate as well as other difficult, brittle components during the damaged technique, crushing (sand). Setting up sand, roads gravel gifted ideal. Because of the feed, sub-feeders, eddy crushing chamber seven areas.

pcl vertical shaft impact crusher, identified as PCL vertical shaft great crusher also called sand making device, is really a sort of device. pcl vertical shaft great crusher is broadly made use of in substitute cone crusher, roller, ball mill types, with affordable framework, easy disassembly and high crushing efficiency. The PCL crusher feed dimension amongst 3mm-8mm, the predicted dimension modest and uniform, and areas sturdiness, less donning areas, servicing handy. Reduced energy usage in comparison with classic energy usage crusher ability for every hour production ability amongst 30-130 tons.

second hand impact crusher Sand performs:

Content from your feed hopper into your crusher, the material is split into two areas because of the sub-feeder, among the many sub-feeder into your high-speed rotation with the impeller, the impeller becoming speedily accelerated, acceleration of around a number of hundred times the acceleration of gravity, then from your impeller 3 uniform flow channel at a speed of 60-70 m / s projectile out, for starters with all the aspect with the self-generated revenues falling by throughout the sub-feeder materials impact crusher, and with all the impression with the vortex cavity lining components, materials lining rebound oblique impression to your top rated with the whirl chamber, but also to vary its course of motion, deflected downward motion of fabric emitted from your impeller form a continual components curtain. This sort of a material during the the whirl crushing cavity by two times along with a number of times the probability of impression, friction and grinding crushing outcome. The damaged materials is discharged from your lessen aspect with the discharge opening. And form a closed cycle screening technique, the 3 basic circulation components damaged into 20 mesh. Content mutual self-impact crusher during the overall crushing system, not in immediate speak to with all the steel components, but with all the lining components shock, friction and grinding, which reduces air pollution angle, to increase some time of mechanical have on. Self-loop, the the whirl chamber internal intelligent airflow gets rid of dust air pollution.

Imported ore price has been cut domestic mining enterprises sell mine

With imported ore prices continued to fall, part of the domestic mining enterprises under threat.

Yesterday (August 28), the "Daily Economic News" reporter learned that, by the downturn in the steel market dragged down imported ore price continues to fall and enlarged decline, the price of some varieties have been significantly lower than the domestic ore. Mine the emergence of low-cost imports, which more than domestic ore lost the price advantage, and also forced the shutdown of some domestic small and medium-sized mining enterprises delisting.

Imported ore price has been "cut"
Imported iron ore market to plumb all the way, because businesses selling pressure significantly expanded ore price decline in the past two days, the market cheap deal emerge. "Said Mysteel analyst Zhu Xian,.

Latest statistics show that to Tianjin Port 63.5% Indian iron ore, for example, as of the 28th, Tianjin port price of 750 yuan / ton, a decrease of 17.6% over the same period last week, a decrease of 20.2% over the same period from the previous month, a decrease of about 44 compared to the same period last year %.

"Daily Economic News" reporter found that more than Indian ore prices fell significantly, other imported the same ore prices have not stabilized, PB powder outside the disk has fallen below 100 U.S. dollars / ton, compared with last year, more than 190 U.S. dollars / ton, the price close to "cut".

Yesterday, the miners usual, the tender, but the basic domestic corporate demand procurement and light reaction. Which, only three cases of tender along with the ending of the auction of the Australian mining, the two Pakistan mine tender ending of the auction.

Many industry insiders told reporters, imported ore price deep down steel prices fell sharply Forced "If you look at the price relationship between the decline after 2008, the ore price not to the corresponding price.

In addition, the steel procurement enthusiasm is not high, the late iron ore prices are still down space.

The data show that as of August 24, the 30 major ports in the country's total iron ore stockpiles at 98.95 million tons, an increase of 830,000 tons over the previous week, for two consecutive weeks rose, the total stock hit a new 23 weeks high. Compared with the same period last year, total inventories increased by 3.74 million tons.

Domestic mining enterprises sell mine
Reporter learned that, due to the imported ore prices remain high for long, the enterprise inside and outside the mine's procurement mostly to comply with a ratio of 4:6. Appear as the low-cost advantages of imported ore, the ratio of imported ore for domestic steel mills rising, which makes part of the domestic mining enterprises deep selling mine "situation.

Yesterday, who said in an interview with the "Daily Economic News" reporter, "If the imported ore ton drop in price to $ 100, the value for money outside the mine more obvious, the buyer also more inclined to purchase outside the mine."

According to statistics, currently 50 mines operating rate was about 62%, while the good times, the start of these enterprises can reach 90%.

The person said domestic ore not to stop production of large area even shuffling, but does have some small mines discontinued phenomenon, "because now outside the mine not only cost advantages, to some extent better than domestic ore use. "

It is reported that 120 U.S. dollars / ton has been regarded as a psychological barrier of domestic ore, imported ore price below that price, domestic enterprises will be a lot of selection of imported ore.

"At present, the proportion of imported ore generally up to about 80%, even 90% or all outside the mine." Steel sources said domestic ore price has fallen to a lot of gains and losses from domestic mines line or the line between life and recently, domestic The mine shutdown delisting phenomenon increased significantly.

In fact, in July, domestic mineral there have been more significant decline. According to the Bureau of Statistics data, the amount of domestic iron ore in June to 125.693 million tons, while the July data fell to 115.461 million tons. Actually discontinued more obvious than the Bureau of Statistics. "Zhu Xian said.

Olympics used green shibang broken machine liner

Recently, reporters learned through market research, sales of sand and gravel production line equipment in the market is very hot, wear-resistant lining of the crusher may be used for the Olympic Games In particular, it is stone ground into the sand is to become a magic weapon for people to deal with natural sand diminishing this critical situation, therefore, stone sand will become a beautiful landscape in the building materials industry.
The past two years, in order to achieve the perfect ending of the "12th Five-Year Plan, the state will vigorously develop the infrastructure, but due to changing market conditions and the lack of funds, many large infrastructure projects in the state of digging to be built, which makes building materials industry has been had a great impact, especially the cement industry has been showing in the first half profit continued to decline, some of the weaker strength of the cement companies make ends meet, has been the delisting eliminated, we can say with cement-based building materials industry a red light in this year's development.
However, a fiery sand and gravel production areas to eliminate concerns about the future development of the building materials industry, the experts predict, sand and gravel production in particular, the mill liner in Shashi production gotta application development in the current, the future will be a hot market not to be underestimated, there are three reasons:
A large national projects appear broken, but some people's livelihood project continues, such as urban subway construction, new rural construction of concrete mixing plant for the production of sand and gravel aggregates of small business .
2, a single development of the cement industry no longer meet the current market environment, opening up a two-way profit point is imperative. From the national focus on environmental development and the national Ministry of Industry began in 2011 released the first batch of backward production capacity of cement companies, cement industry is aware of a structural adjustment, restructuring and development, major changes will be to develop a key step.
shanghai shibang construction Shui Nissan 8000 tons of sand and gravel production line for benefit case is sturdy cement industry's determination to enter the field of sand and gravel production, therefore, the restructuring and development of cement industry but also for the development of sand and gravel industry in China played a significant role in promoting.
3, sand and gravel industry itself is constantly exposed to modern improvement will drive the industry to realize leap-forward development of the new one. It is understood that in ancient times, people learned to go to a house built of stone ground into sand, building a bridge, can be said that the sand and gravel industry in China has a long history.
With the continuous development of science and technology, some problems in the sand and gravel industry in China began to expose the most obvious is the slow sand and gravel production equipment replacement, had a great impact to the quality of the sandstone aggregate. Coupled with the sand and gravel aggregate is the essential raw materials of construction, therefore, the use of advanced, efficient, high value-added technology sand making machine, jaw crusher, impact crusher, crusher composite liner and other equipment will the production of quality sand and gravel to provide important protection to the health of our sand and gravel industry, sustainable development provides an inexhaustible driving force.
It can be said that the building will have gravel, therefore, continue the revitalization of the sand and gravel industry will also be an important indicator of national development, the contribution of the modern system of sand equipment, our infrastructure will be achieved sound and rapid development.
