Coal Crushing Plant

Coal is one of the most important energy, which plays an extremely important role in social and economic development. Development and use of coal, both played a huge role in promoting socio-economic, but also had a significant impact on the environment. Coal gangue and coal bed methane is the main waste generated in the development process which has long been regarded as hazardous substances and hazards gas in the coal industry. Coal gangue is discharged as solid waste in the tunneling, mining and washing process which is a mixture of carbon, clay and sandy shale, with low heat value.

Crushing Plant Overview

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 includes coal crushing and coal grinding. Coal crushing plant consists of many types of crushers and Grinding mills. Coal crushers including: primary Jaw crusher, secondary Impact crusher and Cone crusher etc. Coal mill include Ball mill, Raymond mill, Vertical mill etc.

Coal Crushing and Grinding Process

If the coal block is bigger than the mill's max 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 set before Ball mill as pre-grinding.

More application of SBM Crusher and Mill

Apart from coal minerals, SBM Crusher and Grinding Mill have also been widely used for lots of other various non-explosive mineral materials crushing and grinding, such as quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, iron ore, copper, iron oxide red, and zircon slag, cement clinker, activated carbon, dolomite, granite, garnet, iron oxide yellow, fertilizer, compound fertilizer, fly ash, coal, Ling U.S. sand, chromium oxide green, gold, red mud, clay, kaolin, coke carbon, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, stone, shale, basalt, gypsum, graphite, silicon carbide, thermal insulation materials, etc.
