### Ball Mill LoadingDry MillingPaul O. Abbe

Charging a Dry MillThe general operation of a grinding mill is to have the product impacted between the balls as they tumble. If there are insufficient solids in the mill then the media will strike itself and generate excessive media wear. If too much product then the solid may buffer the impact too much. 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
