The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

#### Ball mill Wikipedia

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. A ball mill consists of a hollow cylindrical shell rotating about its axis. TCalcium Sulfide Precipitation of Mercury During Cyanide,laboratory ball mill, along with NaCN and lime. Calcium sulfide was varied from 0.012 lb to 0.09 lb per ton of ore. One thousand grams of minus 10-mesh ore, 1.25 g CaD (2.5 lb/ton ore), 0.8 g NaCN (0.53 lb/ton solution), 1,000 mL water, and the CaS were added to the ball mill and ground for 45 min.
