If the rod mill feed is 80 passing 12 mm or less e.G.From a closed circuit crusher do not apply a rod mill efficiency factor.Other correction factors such as mill diameter and reduction ratio however do apply.The uncertainty in this correction factor means that it has little value in calculating, w ioc and the efficiency of plant rod mill.
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.
