Introduction to Coal

Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams .Coal, a fossil fuel , is the largest source of energy for the generation of electricity worldwid.

Coal Mining

The goal of coal mining is to remove coal from the ground.There are four main types of coal mines: shaft mine, slope mine, drift mine, and surface (open-cast) mine. coal mining is need crusher or moible crusher,include some optional equipment such as vibrating feeder, vibrating screen, belt conveyors and so on to finish the coal milling process.

Coal Mill

The particle size of slack coal is 0 ~25 mm. The slack coal is often used as combustion agent in steel company, thermal power plant, etc. The consumption of coal is quite large in thermal power plants. Take a 1 million kW thermal power plant for example, coal consumption amounts to 11,000- 13000t a day, which takes 60% ~ 80% of the cost for generating electricity. It is advisable to adopt appropriate coal mill for coal grinding. This can not only improve the utilization of coal, but also contribute to energy saving, environmental protection, economic benefits.

According to the market research, vertical roller mill is used most widely. There are also other grinding mills like traditional raymond mill , roller mill, trapezium mill, etc. can also meet different requirements for grinding coal into different sizes and types. Customers can choose an appropriate coal according to their specific needs.
