ABB reported that it held the most recent of its Gearless Mill Drive (GMD) User Meetings in Lima, Peru, during October 23-24. The conference, a cooperative event between ABB Switzerland and ABB Peru, was the fourth meeting of its type, following a global event held in Switzerland in 2007 and after two regional events in Santiago, Chile, and Sydney, Australia, both held in 2006. The 2009 GMD User Meeting will be held in Switzerland next October. ABB said that, to date, it has installed or received orders for more than 80 gearless mill drive units in 21 countries on five continents. Most recently, it reported that it had received a follow-up order for the Salobo copper mine project which is being developed by Salobo Metais S.A., a subsidiary of Vale. ABB had previously won a contract in late 2007 for delivery of two GMD systems at Salobo. In June 2008, ABB was given an additional order from Polysius, which had been awarded the grinding circuit package by Vale. ABB said Polysius chose it for the follow-on order because of ABB's experience with High Pressure Grinding Rolls (HGPRs). ABB's scope of supply for the additional order comprises two MV ACS 1000 variable speed drive systems, including motors and transformers, for two HPGRs, each powered by two 1,800-kW motors.
