    Screen apertures in the case of closed-circuit operations typically range from 5mm to 6mm in the case of wet screens and typically 10mm for dry screens. Reported power savings are in the range of 15-25 for hard competent ores when compared with traditional semi-autogenous grinding (SAG)/ball mill or stage crushing/ball mill circuits.
