  • Reason For High Reject In Coal Bowl Mills

    Reason For High Reject In Coal Bowl Mills. Fewer mills are however easier to control and capital and installation costs are lower so the number of mills must be decided at the design stage.The high unit capacity sag millball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs which has in turn made many low-grade high. Pulverized coal mills with throats that are too wide will have corresponding low throat velocity in the mill grinding zone that contributes to excessive coal rejects and fires. This is an example
