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 cylinder, which is filled with 3035% of its volume by small steel balls and is rotated through motor. When the cylinder starts to rotate, the balls start to lift under centrifugal and frictional forces and fall back into the cylinder and onto the feed as gravitational pull exceeds those forces (Fig. ).
