Optimization of mill performance by using

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.
