This reducing in size is done by using ball mill. Figure 1: Mechanism involved in size reduction One of the famous machine use in size reduction is ball mill.
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 The ball mill is a key piece of equipment for grinding crushed materials, and it
