The location of the sizing mill is important to allow time for the rod to be controlled cooled and equalized prior to the final reduction, thereby reducing the risk of over-heating of the rod core. This is crucial for special steels which are sensitive to grain coarsening at high finishing temperatures.
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..
mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006). On

Primary Grinding in open End ROD Mills successful since 1919 With MARCYS THE USE of MARCYS Open End Rod Mills for primary grinding is today receiving considerable attention – rightly so. The open end rod mill is an excellent primary grinder because it is efficient and economical for preparing food to tube or ball mills.
ROD MILL CAPACITIES. The above tables list some of the most common Open End Rod Mill sizes. Capacities are based on medium hard ore with mill operating in closed circuit under wet grinding conditions at speeds indicated. For dry grinding, speeds and power are reduced and capacities drop 30 to 50%. ROD MILL General …
