The Metso Outotec® Open Ended Discharge Grinding Mill (OED Mill) is a large grinding mill solution that enables innovative and efficient high capacity circuit designs through the removal of pulp lifters from the discharge arrangement. This facilitates significant reductions in both CAPEX and OPEX. Highest possible discharge capacity through elimination of pulp lifters Maximized slurry transport and impact energy with the lowest possible slurry pool level Reduced CAPEX with novel high-capacity circuit designs Minimized OPEX through the reduction or elimination of grinding media Optimized serviceability and availability with novel discharge wear package IMPROVE PROFITABILITY WITH INNOVATIVE HIGH-THROUGHPUT CIRCUIT DESIGNS With decreasing ore grade quality and operating cost pressures driving the need to process higher tonnages and improve processing efficiencies, high-throughput circuits based on very large grinding mills are becoming an increasingly attractive option in mineral concentration applications. HIGHEST POSSIBLE DISCHARGE CAPACITY The OED Mill delivers the highest possible discharge capacity by eliminating the need for pulp lifters; instead, material is discharged directly through the grates, solving the throughput bottleneck problem often associated with comminution circuit design. The pursuit of high-efficiency pulp discharge systems by mill and liner suppliers is a testament to the potential upside of open-ended milling. MAXIMIZED SLURRY TRANSPORT AND MINIMIZED SLURRY POOLING The OED Mill has been designed to maximize slurry transport and minimize slurry pooling.
