It is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action is lost and, more importantly, rod tangles occur. Maximum rod length is limited to about m (20 ft). This in turn limits the length, diameter, and capacity of rod mills. The heavier rods acting upon the lifters and liners result ...

Tubular Rod Mills. In Mineral Processing Design and Operations (Second Edition), 2016. Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of %. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

Cast grinding balls are suitable for ball mill with a diameter of ~3 m. In the ball mill with a diameter less than ~ 3m, the grinding effect of cast ball is slightly better than that of forged. Because the acceptable impact value of cast grinding ball is only 2~4 joules, cast ball can withstand the impact in the small diameter of ball mill.
