efficient wet grinding rod mills with rods media
Highly Efficient Rod Mill Fote Machinery(FTM)
Rod mills are very similar to ball mills except for the use of steel rods as grinding media. In the rod mill, steel rods grind the ore by rolling and rotating. The feeding of rod mill is 50 mm, and its output particle size is 4 to 35 mesh. Rod mill produced by Fote Application fields of rod mill Applications of rod mill

Jan 25, 2018 The following cost advantages should be considered when evaluating rod mill grinding: Rod Mills use low cost grinding media. Less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media.

Mar 20, 2017 Rod Mills:Mills loaded with rods as the grinding media are used for primary grinding of rocks and minerals. The rods fall from a height and roll down the mill so the rods impart an impact force as well as an abrasive action. The product size from a rod mill is much coarser.

Feb 15, 2005 Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher [2]. Most sizereduction equipment is subject to heavy wear and therefore parts, such as casing liners, hammers and jaws, are designed for relatively easy replacement.
