This progression has, not necessarily, been accompanied by an improvement in the efficiency of power utilisation in achieving the target grind size, but has seen an improvement in the overall efficiency of mineral processing as measured by the overall cost of grinding to the required size for

  • SAG mills (semi-autogenous grinding mills) minevik

    SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency

    The ball size in a mill has a significant influence on the mill throughput, power consumption and ground material size (Austin et al., 1976; Fuerstenau et al., 1999; Kotake et. al., 2004). The basic condition, which must be met while grinding the material in a mill is that the ball, while breaking the material grain, causes in it stress which is higher than the grain hardness (Bond, 1962
