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%

Use of Alternate Fuels in the Cement Industry

Coal is the basic fuel used in the Indian cement industry. While it mainly provides the requisite heat and temperature, the ash content in the coal also combines chemically with the limestone to help form cement clinker. In India, coal will, of course, continue to be the dominant fuel for a very-long time.
