Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

In a study of rodmill discharge openings of different sizes, four pairs of tests were made at speeds of 40, 50, 60, and 70 percent of critical. In each pair the discharge openings were and inches, respectively. The tests were conducted so that the tons per horsepowerhour were nearly the same. This manner of conducting the tests gave about the same amount of subsieve size in each.
