### The Effect of Ball Size Diameter on Milling Performance OMICS

Jan 22, 2015 Milling is the third and final stage of comminution after crushing which involves the reduction of solid particle sizes to micron size level. 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

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. A ball mill consists of a hollow
