  • What s the difference of Ball mill SAG mill AG mill

    Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill rock and a small ball charge ( 10 ) used in Semi Autogenous Grinding (SAG) mills balls of various sizes in Ball Mills and less commonly these days steel rods in Rod Mills.

  • 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.
