Matt Cavedon, General Manager, Project Development at Perseus, noted:
“Perseus is looking forward to the successful deployment of Metso’s state-of-the-art comminution technology, alleviating gearboxes with the benefits of precision control and high efficiency.”
Oskar Gustavson, Technology Director, Grinding at Metso, says:
“The Premier SAG mill and ball mill to be delivered to the Nyanzaga project feature low-speed synchronous motor drives without conventional gearboxes. This makes the mills very reliable and very efficient – a 2% saving in energy consumption when compared to traditional gearbox-driven mills. Both mills are equipped with Metso’s fail-safe Polymer Hydrostatic Shoe Bearing systems, significantly increasing reliability and reducing maintenance costs.”
