In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.
Coal mill is major equipment of cement plant and used for drying and grinding coal. The equipment mainly consists of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system.
As the “black blood of industry”, coal is usually ground into micro size powder, which can ensure a high combustion efficiency. However, different degrades of coal are used in different application with different requirements. Zenith can supply all kinds of coal mills to process coal ores like hard coal, woody lignite and lignite, anthracite coal and petroleum coke. Besides, Zenith’s 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.
