## Ball mill Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sinteringIt works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotatiThe sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent It is especially difficult to teach millCalculate Ball Mill Grinding Capacity
