A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Section snippets Experimental. Mechanical milling was performed by using a planetary ball mill (PBM) under various experimental conditions. Copper powder (% purity, median particle size x 50 = 45 μm, Aldrich chemistry) was used as shown in Fig. 1. Mechanical alloying (MA) was carried out at two types of rotation speeds: low (10, 50, and 100 rpm) and high (300, 500, and 700 rpm).
