A ball mill is a type of grinder used to grind and 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. A ball mill consists of a hollow cylindrical shell rotating about its axis.

Mills used to grind will operate with higher roll speeds 1,500 Ft/min ( M/sec) up to 3,000 Ft/min (M/sec) with roll speed differentials. Roll speed differentials simply means one roll turning faster than the other and is usually described in the form of a ratio, slow roll speed expressed as 1.
