The grinding process in ball mills is notoriously known to be highly inefficient: only 1 to 2% of the inputted electrical energy serves for creating new surfaces.

The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill ...
