Rod Mill

Rod Mills are horizontal rotating cylindrical steel chamber of half filled with steel rods of length slightly less than the length of chamber. The rods are of different diameter. The size reduction is accomplished by the impact of rods as they fall back after being lifted by the rotating chamber. Rod Mill is fitted on a sturdy MS frame. Charging of rods and material is done by the means of opening provided in the chamber. The chamber is turning about the horizontal axis through a reduction gearbox drive through a ½ HP motor. The stepped pulley arrangement is done for moving the Rod Mill at three different speeds. A revolution counter is provided to find out the number of turns. Special arrangement is done to free the Rod Mill from reduction gearbox for charging and discharging the material.
