Effect Of Ball Size In Ball Milling

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes paints pyrotechnics ceramics and selective laser sintering It 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 rotating about its axis The axis of the
