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].

Wet ball milling in a dual centrifuge (DC) (10100mg API, 40 samples in parallel) was used to identify stable nanoformulations. In addition different sized agitator bead mills were used for scaleup to industrial scales. DCand smallscale agitator milling (AM) resulted in small and virtually identical APIparticles.

Planetary ball mills are perhaps the most commonly used ball mills in laboratories for the sample preparation of soft to hard, brittle and fibrous materials. The name of this mill type derives from its unique kinematics: the grinding bowls, which are mounted on the rotating sun disk, rotate in the opposite direction around the centre of this disk.
