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. Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating
