Iron ore operations commonly employ one or more stages of crushing with screening stages incorporated to remove material meeting product size specifications as soon as possible. Lump product (typically between 6 and 30 mm) attracts a premium price compared to fines product (typically less than 6 mm).

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 1.4 to 1.6. 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).
