Rod Mill Grinding Rods 911Metallurgist

Decreasing the rod size from 3 to 2½ inches (76 to 64 mm) at Tennessee Copper resulted in an increase of 22% in rod consumption, which can be directly attributed to the larger exposed surface area of the grinding media This strongly supports the general practice of selecting large rods, but should be considered in conjunction with mill efficiency Rods

Rod mills, how they function Mine

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 14 to 16 Rod mills accept feed up to about 50 mm (2 in) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh) Grinding action is by line contact between the
