Rod mills are less common than ball mills for grinding minerals.The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter.However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices.This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (mcken, verret, & williams, 2006).
