A ball mill is a type of grinder used to grind and 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. A ball mill consists of a hollow

Abstract. Votorantim Metais — CBA's alumina refinery produces 0.9 Mtpa of SGA. Recently the particle size of the rod-ball mill product has suffered an increase of 35% in the +590 μm fraction. This results from higher grinding charge and variation of bauxite blend, with a rise in proportion of higher Work Index bauxite.

A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are
