Optimization of mill performance by using
2015416 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’. By calculating the ratio ‘H/Di’ and using the graph below (Figure 1), the charge filling degree in volume

The ball filling relates to the volume (including voids) that the balls occupy when the mill is completely ground out, ie there is no ore in the mill. This volume is expressed as a % of the total mill volume. Note that these figures should be
