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.

The action of tube mill is similar to that of ball mill. But fine grinding is achieve due to steel balls of smaller size. A worm is provide to feed the material to the mill. The pulverised material is collect at the outlet funnel. In case of large scale production, the air separators may be employ to separate finely ground particles.
