What is a Ball Mill? A ball mill is a type of grinding mill used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. The ball mill 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.
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
