Contract for new mill drive system at Neves Corvo copper mine

ABB was recently contacted to supply the drive system for a new semi-autogenous grinding (SAG) mill at Neves Corvo/Portugal. The contract was awarded in June 2011. Neves Corvo is an underground mine, located 100 km north of Faro within the Iberian Pyrite belt and one of Europe’s most important copper mines. It started operating in 1988, producing both copper and zinc-ore. The company changed ownership in 2004 and is now fully owned by Lundin Mining. ABB’s scope of supply includes two converter transformers, one excitation transformer, an MV frequency converter and one synchronous motor. The MV frequency converter operated motor will improve the grinding process by varying equipment speed as needed. Its low speed operation will allow for removal of the gearbox from the drive train, thus reducing costs and need for maintenance as well as increasing efficiency. It will also improve operation by enabling frozen charge protection, controlled roll back, as well as inching and creeping for service purposes. This new mill will be operated with the world largest single pinion low speed drive system. The available shaft power is 8500kW with a motor speed of 174 rpm. Equipment delivery is scheduled for the third quarter of 2012, with installation and commissioning scheduled for early 2013.
