  • The effects of lifter configurations and mill speeds AIP Publishing

    Abstract. Grinding mills used in the mining industries are the most energyintensive operation and require a large number of wear resistant materials as well. The 1m mill was used to investigate the effects of three lifter configurations, namely Hi (High), Rail and HiLo (HighLow), and mill speeds on the mill performance.
