size reduction based on ball mill

Ball mill Wikipedia

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 axiThe Effect of Ball Size Diameter on Milling Performance,The size reduction is achieved by a combination of abrasive and impact forces between the particles and the milling media as well as the walls of the mill [1]. Ball mills are one of
