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 shellA laboratory size ball mill was used with ball media of sizes 10 m Ball mills are one of the most commonly used milling equipment in minerals processing place, is determined in terms of the percentage of the critical speed of the mill 8 the balls, meaning that the mass of the charge varied with the ball.
