For the greatest particle size reduction, ball mills should be operated at their optimal speed. This speed is normally between 50-90% of the critical speed, which is dependent on the application and material to be ground. At the optimum speed, the grinding media falls down the shell of the mill at the highest point thereby generating the ...

Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. 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 ...
