    The ball mill is very similar to the SAG mill except it has a larger proportion of steel balls to assist in the grinding process. Following grinding in the ball mill the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing. The trash screen (10) removes wood from the old mine workings that may have found its
