• Semi-Autogenous and Autogenous Grinding Mills (SAG Mills

    Ores which are comprised of sufficient competent pieces are amenable to AG mills. For such ores AG mills perform crushing fine and coarse grinding steps of size reduction. On the other hand semi-autogenous grinding (SAG) mills use steel balls as an additional grinding media.
