Design And Drawing Discharge Diapragm Ball Mill

  • Mill power draw modelsSAGMILLING

    The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput All models generally assume that a mill is fitted with efficient liners and that the grate design neither limits passage of pebbles and pulp nor permits re circulation of pulp back into the mill.
