    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.

  • Which type of coal use by cement industry.

    Bituminous coals make the best coke and are in any case the most common, and these are most often used in the cement industry, although steam coals are occasionally used. When burning a pulverised fuel, higher volatiles are preferred because they speed up ignition and allow a coarser grind to be used.
