Crushers and Grinding Mills used in Coal Mining Processing Plant
Because coal was the basic energy source that fueled the Industrial Revolution, the resulting industrial growth supported the large-scale exploitation of coal deposits. Fifty years ago when most coal mining was done manually, underground mines accounted for 96 percent of the coal produced each year. Today, almost 60 percent is produced from surface mines. The mining of coal from surface and underground deposits today is a highly productive, mechanized operation.
During the coal mining process, first, bulldozers clear and level the mining area. The topsoil is removed and stored for later use in the reclamation process. Many small holes are drilled through the overburden (dirt and rock above the coal seam) to the coal seam. Each is loaded with explosives which are discharged, shattering the rock in the overburden. Giant power shovels or draglines clear away the overburden until the coal is exposed. Smaller shovels then scoop up the coal and load it onto trucks, which carry the coal to the preparation plant.
Once the coal is removed, the land is returned to the desired contour and the topsoil is replaced. Native vegetation and/or trees are planted. Coal companies operating surface mines must comply with strict requirements and regulations of the Federal Surface Mining Control and Reclamation Act. A crucial part of the surface mining process is restoring a mined site to acceptable ecological conditions, which means it must be made as productive as it was prior to mining.
In coal preparation plant, you need coal crushers to crush large bulks and coal mills to produce coal powder particles. Our coal crushers and mills are primarily used in open-pit mining method to extract coal from the mines in its concession areas which are also suitable of underground mining method.
Coal crushing plant works to grind big coal bulks to smaller meeting the production size requirement. Coal crusher usually refers to jaw crusher, cone crusher and coal mill usually chooses ball mill, vertical coal mill. Here is the whole process of coal crushing. You can get a general idea about that.
Coal grinding plant can be used after coal crushing and screening. SBM can offer you ball mills, and coarse powder grinding mills for coarse coal grinding, ultrafine mill and MTM trapezium grinding mill for fine coal grinding. Also, you can choose our vertical coal mill for large-scale coal pulverization.
