    Ball mill - Wikipedia

    A ball mill is a type of grinder used to grind and 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.mining top down approach ball milling - phspipeline,mining top down approach ball milling 200*125 Double Roller Coal Crusher Double Teeth Roll Crusher .
