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 axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. T
6. Appli ion scope. At present, the most widely used grinding equipment in the ore dressing plant is ball mill and rod mill. As far as the working principle is concerned, both ball mill and rod millare the same. But for many people, ball mill and rod mill are just like a pair of "twin". These two types of mills belong to the long cylindrical ...
