ball mill mechanism

Ball mill - WikipediaA 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. A ball mill consists of a hollow.ball mill mechanism,Grinding in Ball Mills: Modeling and Process . - Semantic Scholarin modeling and control of the grinding process in industrial ball mills.
