There are three basic types of mill; ball mill, rod mill and autogenous mill. In a rod mill it is rods which span the length of the mill. Rod mills only can make use of a feed size of 50 mm and produce products between 250 – 3000 microns. Rod mills uses inside lining to cascade rods. Rod mills are used as a primary milling approach
