Coal Grinding Mill

Brief Introduction of Coal Grinding Mill:

Coal grinding mill, which is also known as air-swept coal mill or coal milling machine, is used to pulverize and dry coal before it is blown into the power plant furnace in the coal-fired power plants. As the “black blood of industry”, coal is usually grinded into micro size powder, which can ensure a high combustion efficiency. However, different degrades of coal are used in different application with different requirements. Our company can supply all kinds of coal grinding mills to process coal ores like hard coal, woody lignite and lignite, anthracite coal and petroleum coke. Besides, our coal mills can be installed with other assistant equipment, such as the bag-type dust collector and electric magnetic iron mover, to meet the requirements of any industry.

Working Principle of Coal Mill:

Feeding device sends raw coals into drying oven; drying oven is equipped with special lifting plate to scatter coal and make coal get strong heat exchange so that raw coal is dried; dry raw coal is sent into grinding storehouse via double-compartment plate. Grinding storehouse is equipped with grinding balls so that raw coal can be crushed and ground into coal powder in this compartment, while, a dedicated induced draft fan carries over pulverized coal together with gas through discharging device, and coarse particles return back grinding storehouse for re-grinding.

Features of Coal Grinding Mill:

Air-Swept Coal mill is with rim drive, motor drives the grinding mill to rotate through reducer and gears. Grinding storehouse adopts modular layout so that coal mill has greater adaptability to the moisture of raw coal, improving the mill's grinding capacity. Feeding device is with oblique blinds structure which enhances the heat exchange capacity of grinding mill and effectively prevents materials blocking inlet.
