Ball Mill Critical Speed
Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range. Pebble mills are usually run at speeds between 75 and 85 percent of critical speed. Ball Mill Critical Speed . The black dot in the imagery above represents the centre of gravity of the charge.

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 ...
