The influence of mill speed and pulp density on the
The pilot mill is also equipped with a sensor measuring the ball and pulp toe and shoulder angles (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73 solids as the total media angle does not change.

Size Reduction.docxIntroduction Size reduction
Based on the graph of percentage of weight particles versus aperture size for coarse stones the distribution of particle size was not uniform after ball milling. However the particle size was reduced after the ball milling. This was shown when the weight retained on receiver after the ball milling was higher than before the ball milling. This because the ball milling was grinding the coarse
