The rod mill performs best when making products having a top size of 4 mesh to 16 mesh operating in open circuit, or as fine as 35 mesh operating in closed circuit with a screen or other sizing device. The rod mill accepts feed ore as coarse as 1 1/2" top size although better performance is obtained by restricting ore feed size to 3/4".
The coarser fraction is then fed to the ball mill. The rod mills are normally operated in open circuit and ball mills normally are operated in closed circuit. Some common circuits are illustrated in Figure 8.2, Figure 8.3, Figure 8.4. Download : Download full-size image; Figure 8.2. Circuit 1: Rod Mill Open Circuit, Ball Mill Closed Circuit.
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.
