These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media. However, one the challenges with AG mills is that properties, such as hardness and abrasiveness, of the ore can vary, resulting in inconsistent grinding behaviour.

between the rod mill and ball mill values for a given ore type. These differences may be caused by a variation in ore hardness by size (12.5mm for RWI and 3.35mm for BWI), and/or grain size properties. The Bond rod mill work index is used to calculate the power requirement at intermediate size, i.e. from 12.5mm to about 1mm. The test has been ...

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 particle-size measurement device and size-control cyclones. Get Price
