  • Comminution

    Dry grinding is necessary with some materials due to physical or chemical changes which occur if water is added. It causes less wear on the liners and grinding media and there is a higher proportion of fines in the product which may be desirable in some cases. Wet grinding is generally used in mineral processing operations because of the overall
