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.
