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.

4.Reasonably add steel balls. During the long period of operation, the ore grinding will lead to the wear of steel ball. It leads to the ratio change of different size steel balls. It changes the grinding product fineness and even influences the grinding efficiency of ball mill. Therefore, the operators of ball mill need to check the steel ball
