After coal comes out of the ground, it typically goes on a conveyor belt to a coal preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Coal processing is necessary in coal usage and supplying right size coal ores for coal industry. Coal processing is also the important coal mining equipment which process coal with crushing, grinding, conveying and screening, etc. During this coal processing, the used industrial equipment can be called coal processing equipment.
Coal processing equipment
In the coal-fired electric generation plants, to ensure complete combustion, we use coal crusher and coal mill to crush and grind coal into small pieces, thus it can increase the contact area, increase operation rate.
In Coal Gasification Process, crushing and milling is first step, and also the important step.
So in the coal processing, coal crushing and milling process are the eaaential process. In this process, coal crushers and coal mills are essential coal processing equipments.
Coal processing plant
Coal processing plant is the industrial equipments used for processing coal materials in coal mining industry. Coal processing plant mainly inlcudes coal crusher, coal mill, coal feeders, coal conveyors etc. Usually, coal jaw crusher is taken as primary crushing equipment or crusher machine for first crushing stage. Cone crusher and impact crusher are used as secondary crusher equipments. After crushing process, we apply coal mill such as ball mill, raymond mill, vertical mill as grinding machines or equipments for next grinding process.
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.
