Ball mill - Wikipedia

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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the

In a ball mill particles break primarily by impact or crushing and attrition. It seems however that impact breakage is predominant at coarser particle sizes whilst attrition is the main reduction mechanism at finer sizes. Experience shows that small balls are effective for grinding fine particles in the load, whereas large balls are required to deal with large particles. In addition, feed
