Autogenous and Semi-autogenous Grinding Circuits
primary crushed ore enters the SAG or AG mill, gets ground to a "transfer size" where it exits the mill and is then passed to the closed circuit ball mill circuit.

Ball Mills vs Rod Mills
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..
