Coal in the cement industry

Coal in the cement industry Cement manufacturing consists of raw meal grinding, blending, pre calcining, clinker burning and cement grinding. Limestone, CaO, SiO2, Al2O3 and Fe2O3 are crushed and milled into a raw meal. This is blended and preheated in a preheater cyclone. Preheating of raw feed increases the energy efficiency of the kiln as the material is 20-40% calcined at the point of ...
