Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer ...

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.
