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].

Abstract Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the application of planetary ball mills has extended to mechanochemical approaches.
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.
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.
A planetary ball mill is known to install pots on a disk, and the pots and the disk are simultaneously and separately rotated at a high speed. The high speed of rotation of the pot and revolution of the disk make the balls move strongly and violently, leading to fine grinding of a product due to generation of large ball impact energy.
