distribution, thus obtaining a finer and better performing cement. Grinding aids act at two levels: in the mill, with the reduction of cement coating on grinding media and mill lining, and in the separator, with the improvement of classification process. Detailed description of the use of grinding aids in cement industry is reported elsewhere [7].

Optimization Of Mill Performance By Using

The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height ‘H’ from the charge to the shell and the internal mill diameter ‘Di’.

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.
