Exploring ball size distribution in coal grinding mills
01/05/2014· Fine BSD generally enhances milling rate for uncontaminated coal feed. Abstract. Tube mills use steel balls as grinding media. Due to wear in the abrasive environment it is necessary to charge new balls periodically to maintain a steady balanced ball charge in the mill. The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill
