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 of the sun wheel is opposite to that of the grinding jars ( ratio: 1:−2 or 1:−1).
