Ball mill - Wikipedia

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 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 rotating about
