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 ...
