Ball grinding can be carried out in either dryoperation or wetoperation. The former is widely used in coalfired power plants and cement industry, and the latter is widely used in metal and nonmetal mines. There are three types of mills used: grate ball mill, overflow ball mill, and peripheral discharge ball mill.
or smooth wave type. Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based

Uses of a Ball Mill Liner. The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.
