• #### critical speed of ball mill

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.
