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

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise Most of the energy useless lost during ball mill operation, leading to low it efficiency But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill
