Coal crushing

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.

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 plant 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 equipment introduction

For coal crush, SBM jaw crusher has been widely applied for coal primary crushing. If needed secondary crush, there are CS cone crushers, hydraulic cone crusher for your choice. Also, impact crusher is popular as tertiary crushing. After crushed by impact crusher, final products will be of cubic even shape.
