Limitation Of Energy In Grinding In Ball Mill

between the balls with a maximum limit of number of balls not exceeding 50 of the mill capacity for proper grinding. The shell is rotated at a speed which will cause the pellets to cascade thus reducing particle sizes by impact. It has been proposed that in the plastics industry the term ball mill be reserved for metallic grinding media .
