Particles up to 10 mm can be handled in these mills but usually the feed consists of particles less than 150 m. The product has a relatively narrow size range. Since there are no moving parts or grinding media involved, product contamination and maintenance costs are relatively low. However, the energy efficiency of such mills is relatively low.

From 74% the media angle exponentially increases with pulp solid content. Unstable milling conditions starts to occur. The Sensomag® clearly detects the load expansion. (Figure 8.) This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate.

If the feed to the mill is reduced to attempt a finer grind, the reduction ratio increases, trying to produce a product finer than the rod mill should be capable of producing. For both cases of abnormal reduction ratios, a correction factor, F 6, is applied to the Bond work index, where (3.40) F 6 = 1 + R − R RO 2 150 where
