Rod mills are very similar to ball mill machines, except they use long rods for grinding medium. The rods grind the ore by tumbling within the the milling equipment, similar to the grinding balls in a ball mill. To prevent the conditions leading to grinding rod charge tangling, the length to diameter ratio of rod mill is maintained at 1.4 to 1.6.
