Effect of Rod Mill Feed Sizing on Grinding Performance
Rod Mill Feed Size & Size Distribution 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 ...

During milling, the crystallite size of the AZ31 Mg matrix decreased steadily with the increase of milling time. After milling for 110 h, the crystallite size of the Mg phase of the alloy with 18 wt.% and 27 wt.% Ti additions was refined to 86 and 66 nm, respectively, leading to the formation of a nanocrystalline Mg matrix microstructure.

Turn-Key Ore Processor
We offer them with either a hammer mill or a ball mill. Our 4-5 tph system comes with a ball mill only. The hammer mill version of our turn-key ore processors is less initial cost, but higher maintenance cost ($10-15/ton, plus down time). It will produce ground material with 70% passing a 30 mesh screen and 50% passing a 50 mesh screen.
