Tonnes of grinding media, normally in the form of steel balls, are consumed by all process plants having mills as part of their comminution process. The grinding rate increased as the ball charge mass increased as a consequence of the higher grinding media pressure. However, considering the specific energy for the different charge masses, the faster grinding rate at the higher charge mass was the result of a higher specific energy.

The present invention is directed toward a material handling, processing and milling facility which utilizes ball milling as a means for material grinding, mixing or mechanical alloying of materials. The system includes an automatic ball charging, agitating and indexing assembly, constructed and arranged to deagglomerate and directly distribute a plurality of grinding balls to the facility. Grinding media contain balls of different sizes in designed proportions with large sizes in feed end and small sizes in discharge end. About 27 to 35 % volume of mill is filled with grinding media. Equilibrium charge is that charge where compensation for wear can be done by balls of one size only usually the largest size in the compartment.
