The two most used methods for grinding graphite ore are ball and rod mills: A cylindrical shell that spins about its axis is used in ball milling. Graphite ore and chrome steel or stainless steel balls are placed inside the shell. An abrasion-resistant material, usually a manganese-steel alloy, is used to make the interior of the object.

Ball Mills vs Rod Mills

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 ...
