Effect of Rod Mill Feed Sizing on Grinding Performance

Typically, feed to rod mills comes from closed circuit crushing with screens with a top size of 1 to 1¼", or 25 to 32 mm (F80 of 15,000 to 20,000 µm). Deviations above this size have often been associated with extremely poor efficiency, as measured by the Bond Operating Work Index, especially on ores with high Bond Laboratory Work Indexes.
