    Research of iron ore grinding in a vertical-roller-mill

    The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle

    Reducing grinding energy and cost — magnetite iron ore

    Efficiency of the comminution operations is traditionally assessed based on operating cost and energy consumption. Traditionally, the lowest operating cost was achieved by multi stage fully autogenous grinding due to elimination of steel grinding media costs which may represent up to 50 % of the grinding cost. Significant reduction of the cost associated with grinding was achieved over the
