placed in vials. The vial is from stainless steel cylinder with 11/4 inch diameter and 120 mm length. The stroke of the shaker is 54 mm at 233 rpm. The number of cycle is 4 million cycles. The steel ball sizes are 1/8, 5/32, 3/16 and 1/4 inch. PSA results show that there is no certain correlation between the steel ball size and particle size.Web

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.
