Coal mill is also called coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mill and vertical roller mill. At present, most cement plants use coal as the main fuel in the clinker production process.
The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency. Small balls are effective in grinding fine particles in the load, whereas large balls are required to deal with large particles of coal or stone contaminant.
Product Introduction. Coal ball mill is a machine that crushes and grinds the coal briquette into pulverized coal. It is important auxiliary equipment of pulverized coal furnace. During the coal grinding process, the coal is crushed and its superficial area increases continually. To add new superficial area, the bond between solid molecules must be overcome, so the energy is consumed.
