Ball Mill Loading - Wet Milling - Paul O. Abbe

Charging a Wet Mill – The general operation of a grinding mill is to have the product impacted between the balls as they tumble. Unlike dry milling, wet milling is more straight forward and more forgiving in terms of charging the product. As with dry milling there should be at least 25% liquid to fill the void space plus a bit more to insure the balls are striking product and not each other.

Ball Mills - an overview | ScienceDirect Topics

Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge.
