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. The large balls tend to break down the coarse

pacts. This grinding mechanism is required in SAG and FAG mill applications. 2. PERMEABILITY The main size reduction in this mechanism is carried out in the ball charge. The liner design needs to be such that the charge is "opened-up " (permeability) to al-low bigger grains to be drawn into the ball charge where they will be reduced.
