Coal Crusher Knowledge

Coal crusher applied for the station boiler

Station boiler is a boiler providing steam to the turbine generator in thermal power plant, including boiler and ancillary equipment. Fuel is burned in the boiler and releases heat energy, and heat transfer through the metal wall of the boiler water into a certain pressure and temperature of superheated steam, then steam into the turbine, the turbine-driven generators. Total thermal power generation capacity worldwide is about 70%, 80% in China. Therefore, the boiler and its role in terms of energy consumption or from the point of the development of the national economy have a significant influence.

Most of station boilers’ fuel is coal, so coal crusher is the main crusher equipment in thermal power plant for crushing coal.

We should make optimal design of a coal crushing system. In order to promote the concept of coal particles and prefabricated, we use prefabricated, dry coal shed stacked, two broken and three screening can be a fundamental solution to block coal bunker coal, the furnace bed material quality degradation trends, improve coal preparation of system reliability. In this coal crushing process, SBM coal crusher relies on its unique advantages in a wide range of applications in the station boiler system.

Coal crusher used in coal processing company

Coal processing is as follows: After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. During this coal processing, the used industrial equipment can be called coal processing equipments.

Meet the requirements of coal particle size selected. Featured the coal crusher can handle a certain size range, over the range of large to go through a break before washing. Coal jaw crusher is used widely as a efficient coal crusher and applied in coal processing company.

Some coal is a mixture of coal and waste rock symbiotic parting of coal, in order to choose the coal that needs to be broken into smaller particle size, separation of coal and waste rock. The most common case is to be elected in the primary election machine coal crushed to 13mm or 6mm following, and then sent to re-elect re-election machine.

Size to meet user requirements, the products or coal broken are after the election to a certain size. According to the product size broken, broken job can be divided into coarse pieces (the crushing to 50mm and above), in pieces (broken into 25-6mm), small and fragmented (broken into 6-1mm), crushed (1mm or less). So depending on the above parts, we need primary coal crusher, secondary coal crusher and tertiary coal crusher for different crushings.

How to operate a coal crusher rightly

1. Check the functioning of the coal crusher that whether there is an exception within the percussion sound. Once there will be exceptional circumstances should immediately stop working. This is the first and important step for coal crusher installation.
2. Note the pump operation, regular checks throughout the oil flow indicator, oil temperature and oil pressure indicators and so on. After the cooler the oil temperatures should not exceed 45-53 ℃, oil that will be back temperature should not exceed 60℃ and the department of suspension in time up to the oil.
3. Check the tightness of V-belt using the thumb pressure to measure V-belt tension. You should do it carefully according to the coal crusher manual.
4. Always check whether coal crusher beams, the frame the connection between body and machine pin is loose.
5. Check whether coal crusher liner is loose, missing and wearing.
