  • 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 then they cascade down (or drop down on to the feed), from near the top of the shell.
