A ball mill is a kind of grinder that grinds and blends materials for the purpose of mineral processing, paint production, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: the balls are released from the top of the shell and then crush and grind the material to fine powders.
