In this context, modeling of fullscale continuous ball mills could provide significant insights and help process design (King, 2001). Ball milling, where balls hit and grind particles in a rotating horizontal tube, is reported to be an inefficient unit operation (von Seebach et al., 1996, Fuerstenau and Abouzeid, 2002).

Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 3548 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.
