F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8" to 1". Horizontal mills require much smaller media, as small as 0.05 mm to 2 mm. To read detailed specs and submit a quote, click here for our metallic media or here for our non-metallic media.
