The choice was to use two MH2 mills (1350×1500). These mills are designed for dry grinding of the material, have an internal drum volume of m3 and a total load of grinding bodies up to tons. The calculation showed that the mill of the first stage would be loaded with an assortment of steel grinding balls with an average diameter of 63 mm.

A section cutthrough of ball mills. 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.
