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 ...

A ball mill consists of a cylindrical steel drum (with the size of 2 to 5 m in diameter and 3 to 15 m in length) and steal balls (up to 25 cm in diameter) inside of it (see Fig. 1). The drum is being rotated by means of an electric drive (with power consumption of up to 1 MW). The raw material is fed into the mill at the inlet side of the drum by means of a feeder and the grinded material is ...

The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact and grind the material in the cylinder to grind ...
