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 mills, which grind coal to a target size prior to boiler combustion, are important auxiliary equipment in thermal power plants. Their coal grinding efficiency is closely related to the economy of the power plant, as discussed by Masiuk, et al. [].The control requirement for a pulverizing system is to guarantee that the coal load in the ball mill is close to the optimum level.
