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.
If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 tonhr of powder and energy requirement
