:: New Thickener Drive from Outokumpu
Australian-based Outokumpu Technology Pty Ltd has developed a new range of drives for larger thickeners used by the mineral-processing industry. The Supaflow® Column Drive (SCD) series of rake drives and lifting devices is designed for thickeners with diameters in excess of 40 m. The drives are available with torque capacities of up to 6,500 kNm. They feature a commercial one-piece ring gear with oil-bath lubrication; a splined drive from the reducer to the pinion; a self-aligning lower pinion bearing; a hydraulic drive to ensure load balancing between the pinions; and a rake lifting device which can travel up to 1,200 mm. According to Outokumpu, the first SCD was tested earlier in the year and has been exported for use at Anglo American plc's Skorpion zinc project in Namibia.
