We studied standard grinding balls with diameter 110 mm before and after service. The chemical composition of the steel used to make the balls was determined by spectroscopy and turned out to be as follows (in wt.%): 0.802 C, 0.733 Mn, 0.474 Cr, 0.201 Si, 0.161 Ni, 0.008 S, 0.017 P.
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].
