    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.Ing the mill throughput when the modernization con sists of replacing a classifier of an older generation. The high efficiency classifier allows an increased feed of fresh material to the ball mill by avoiding the return of fine material to the mill and corresponding overgrinding.
