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.
A laboratory scale planetary ball mill ( Retsch PM400) was equipped with a test rig which enables the observation and recording of the grinding ball motion inside the grinding chamber. A high speed camera was fixed on the sun wheel ( Fig. 1 ). Lighting is supplied by several LEDs and spotlights, respectively.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

The capacity of 60L largescale production planetary ball mill is expanded on the basis of small laboratory ball mill, which is more suitable for the mass production stage after the successful sample preparation stage. Working principal: It imitates the direct revolution and rotation of the sun and the planets, so it is called planetary ball mill.
Planetary ball mills are well suited to grind small samples in laboratory settings. But the great expense of scaling them up to full production size has so far limited the widespread use of planetary milling in actual manufacturing.
