Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.

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 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 cylindrical

Information About Loci/CHEM. Loci (pronounced lowsigh, the plural of locus) is a C++ library and declarative programming framework that efficiently maps numerical algorithms onto parallel architectures. The approach is logicbased so that it allows a description of what the code should accomplish, but it does not dictate how to accomplish it (as in imperative programming).
