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.

3. A cement grinding mill "A" with a capacity of 50 tons per hour utilizes forged steel grinding balls costing P12,000 per ton, which have a wear rate of 100 grams per ton cement milled. Another cement mill "B": of the same capacity uses high chrome steel grinding balls costing P50,000 per ton with a wear rate of 20 grams per ton cement milled.
A profiled and wear-resistant liner is installed in the mill to transfer energy to the grinding charge more efficiently and to protect the mill shell . Grinding in ball mills is the most energy-intensive comminution operation; for instance, about 110 kWh of electrical energy are consumed per ton of cement produced.
This formula shows the rate of wear at any instant. Since rate is always equal to the differential of space with respect to time, then R = dw/dt in which dw is the weight of material worn off in a very small interval of time dt. This formula gives the total number of balls of diameter between Da and Db.
