A mill lining is disclosed, intended for e.g. a primary or autogenous mill in the mining industry. The lining comprises shell plates and lifter bars made from elastomer material and mounted in a mill drum. The lifter bars extend substantially in the axial direction of the mill drum and project into the mill drum beyond the inner surface of the shell plates.
Heavy-duty lifter bars have castings for larger ball mills and SAG mills. Sag mill Lifter Bars are available in a range of widths, heights and rubber or composite profiles. Lifter Bars are designed to be sacrificial linings to protect grinding mill shells and to enhance the movement of the charge for optimum throughput and grinding performance.

Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a ...
