The power needed to operate a rod mill could exceed 30 of the power used in a ball mill When they are worn rods must not stretch but break in rather small pieces so that they can exit the mill The energy consumed by rod mills could be from 10 to 30 higher than the energy consumed by …
Rod consumption varies widely with the characteristics of the mill feed, mill speed, rod length, and product size; it is normally in the range 0.1-1.0 kg of steel per tonne of ore for wet grinding, being less for dry grinding. Rod mills are normally run at between 50 and 65% of the critical speed, so that the rods cascade rather than cataract
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency [5]

Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod.
Ball/Rod mill Literature . The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.
