Rod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by

  • Comparing Used Ball Mills Vs Used Rod Mills

    In a ball mill the actual balls in the machine need to cascade in order for the grinding to be accomplished. Because of this more energy is needed to power up a ball press as opposed to a rod press. Rod mills can be operated at lower peripheral speeds resulting in reduced energy costs.Difference between Rod mill and Ball mill Fodamon ,For different grinding methods, mill structure, operating conditions and medium shape, the medium filling rate has a suitable range, too high or too low will affect the grinding effect. Usually the filling rate of ball mill is 40% -50%, and that of rod mill is 35% -45%.

  • Comparison of the Primary Grinding of Taconite in a Pilot

    The purpose of this study was to compare the performance of a mill charged with rods with the performance of the same mill charged with balls at the pilot scale.
