    The circuit comprises a SAG mill 12 m diameter by 6.1 m length (belly inside liners the effective grinding volume) two pebble crushers and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity. In closed circuit grinding a high efficiency separator (O-Sepa or Sepax Sepol) is in operation which separates the material that is ground from the mill in to coarse and fine. The fine material is the product while the coarse material is recirculated back in to the mill for further grinding to the required fineness.
