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.

the preferred choice for size reduction. The problem with tumbling ball mills is that they are extremely wasteful in terms of energy consumed (Wills, 1992).
