The ball-mill sample preparation procedure is both quantitative and fast. No powdering, weighing and sonication steps are needed in the sample preparation. The complete procedure takes 2 min (milling and extraction) and 5 min (centrifugation), respectively, much less than the conventional method in which sample preparation takes approximately 45-90 min.

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.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. 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].
