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 ball mill rotates clockwise at various constant fractions N of the critical speed of rpm, at which the particles begin to centrifuge. The charge consists of both steel balls and rocks with a range of particle size distributions (PSD). The default charge consists of steel balls with diameters uniformly distributed between 50 and 100 mm ...
