Optimization of mill performance by using SciELO

For a better understanding of the decrease in the grinding efficiency, the media and pulp angles are recorded by the Sensomag®. From 69 to 73% of pulp solid content, the media angle keeps a constant value (184°) and the grinding zone fills up but remains unsaturated (media angle > pulp angle). From 74% the media angle exponentially increases ...

Ball Mill Loading Dry Milling Paul O. Abbe

50% media charge Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space Add to this another 10%15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading.
