coal crushing plant

coal crushing plant

In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove, 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm. So coal processing in coal preparation plant includes coal crushing and coal milling.

Coal crushing machinery

Coal crushing machinery consist of many types of crushers and grinding mills. Coal crushers including jaw crusher, impact crusher, cone crusher etc. Coal mill include ball mill, vertical mill, raymond mill etc.

Coal Crushing and Grinding Process

If the coal block is bigger than the mill’s max a input size, it must be crushed before grinding. The crushing plant common includes Vibrating feeder as feeding material to jaw crusher, which is as primary jaw crusher. If need secondary crusher, Cone crusher or Impact crusher can be used. After primary crushing, the coal can be feeding to Ball mill to fine grinding. To increase Ball mill effective, the vertical coal mill or coarse powder mill can be setted before Ball mill as pre-grinding.
