Rod Mill Description and Specifications for Lab Tenders
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
