  • Cement Kilns: Size Reduction and Grinding

    Crushers are used to reduce material in lump form to a size sufficiently small to be fed to a mill for fine grinding. The cement industry processes requiring fine grinding are rawmix preparation, fuel preparation and grinding of clinker to make cement. All three may require a preliminary crushing stage. In the case of raw materials, attempts have always been made to minimise the amount of

  • Cement Kilns: Size Reduction and Grinding

    Coal, as used by the cement industry, rarely needs crushing. Clinker, as produced by early static kilns, emerged as large lumps, and crushing was always required before grinding could take place. Rotary kilns by contrast produce clinker that is typically below 50 mm and does not need crushing. However, every rotary kiln occasionally produces larger clinker, or may contain large slabs of kiln coating material, so
