52 the milling process takes place during rotation as a result of the transfer of kinetic energy of the moving grinding media into the grinding product. The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material

energy adjustment from 1.7 mm to the mill transfer size T 80 using Bond’s Law (Starkey & Larbi, 2012). The Bond equation is used to calculate ball mill specific energy from T 80 to the final product P 80 size. The total circuit specific energy is the sum of theW .

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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. A ball mill
