Profile of air-swept coal mill

1. The air-swept coal mill is used for grinding and drying equipment of various hardness coal, it is mainly composed of feeding device, main bearing, rotary part, transmission device, front-rear device, high voltage starting device and lubrication system.

2. It is widely used in cement building materials, thermal power generation, metallurgical industry, chemical industry, etc., the structure of air-swept coal mill is reasonable, the grinding efficiency is high, it is the ideal equipment for the preparation of coal powder.

Advantages of air-swept coal mill

1. Reliable operation, continuous operation, large production capacity.

2. Optimize support system, improve lubrication structure and reduce system resistance.

3. Reduce the power consumption of single - yield and save 20-30% of power consumption.

4. The steel ball and the cylinder length are properly distributed, and the yield increases by 15%-25%.

5. The new material lining board is adopted to increase wear resistance, prolong the service life of the lining board and reduce the number of change of equipment.

6. The feed device adopts the slanted window type structure, enhances the heat exchange capacity of the mill, and it can effectively prevent the coal grinding import phenomenon.
