The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.
by the total charge, Jb the fraction of the mill volume that is occupied by steel balls and E the voidage of the balls and media. U is the fraction of the voidage that is filled by slurry. 3 v is the volume fraction of solids in the slurry.
