    Energy is mainly consumed on the wear of grinding balls and mill housing, friction heating the material etc. The advantages of ball mill there are large unit capacity, achievement degree of fineness corresponding to a specific surface of 5000 cm2 g, simple construction, high reliability and well designed scientific justification.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.
