Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes. 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. Ball mills are used for grinding materials such as coal, pigments, and feldspar for pottery.
