The investigation has demonstrated that the grinding capacity of a mill is maintained when balls are replaced by pebbles, up to about 30% of the charge volume. The energy dissipation and the surface area for grinding are reduced as the pebble volume increases, and it reasonable to assume that the pebble wear compensates for these changes.
When the proportion of pebbles in the mill charge was low (up to 30%), the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate. This could be due to size segregation in the mill. CITATION. Nkwanyana S and Loveday B. Addition of pebbles to a ball-mill to improve grinding efficiency.
