Mill (grinding)Wikipedia. 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. Autogenous mill.
