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 hollow cylindrical shell rotating about its axis The axis of the

How I built a quick and easy homemade ball mill

The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer It had a pulley for a finetoothed belt on it It was left in place and it seems to drive the heavy round rubber belt well without slipping The motor was mounted using screws on only one side, which were deliberately left loose This allows the motor to pivot downward under its own weight to put tension
