Optimization of mill performance by using

Optimization of mill performance by usingBy calculating the ratio 'H/Di' and using the graph below (Figure 1), the charge filling degree in volume could be estimated. The number of visible plates on the shell liner could also be counted and an angle could be calculated (α) but the accuracy of this method is far lower than the measurement of the vertical height from the charge to the roof.
