Cast Grinding Steel Balls - 911Metallurgist

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 ...

Cast Grinding Steel Balls - 911Metallurgist

In primary ball milling, wear speed is largely independent of ball diameter and mill volume. (The same is true for secondary, tertiary, and regrind grinding.) In these applications, Equation 4 can be used to quantitatively predict how ball size and ball volume charges will affect wear rates. For example, a 5% increase in charge volume (42% ...
