DetailsCement production is a complex process that begins in the raw mill, where limestone and other materials are pulverized and mixed. In the kiln, the raw materials are subjected to high temperatures and transformed to clinker. Clinker is transferred to the finishing mill, where it is ground and mixed with gypsum to produce the final product.
DetailsCoal 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.
