Understanding the mechanism: How does a ball mill work?

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, and ceramics. It works on the principle of impact and friction between rotating balls and the powder materials. The ball mill consists of a rotating drum and a hollow cylinder filled with grinding media, typically ...
