A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
Ball Mill. The proven classical option for cement grinding.

Whenthe ball mill for fine grinding, it is preferable to use a smooth or wave ballmill liner. Because they make the medium slide androll, the grinding and stripping action is strengthened, which is suitable forthe second grinding. Usuallythe thickness of the ball mill liner is determined by the diameter of the ballmill, typically 50-150 mm.
