ABB delivers two Gearless Mill Drive systems for the Climax Mine restart project

Tuesday, December 11th, 2007

ABB, the leading power and automation technology group, has won an order worth $20 million from Climax Molybdenum Company for gearless mill drive systems at the company’s Climax mine in central Colorado (USA). Climax Molybdenum Company is the world’s leading molybdenum producer and supplier.
For the Climax Mine restart project, ABB will deliver two Gearless Mill Drive (GMD) systems. One unit, rated at 15’000 HP (11.2 MW), will power a 34 feet (10.36 meter) semi-autogenous mill. The other unit, rated at 12’000 HP (8.9 MW), will drive a 22 feet (6.7 meter) ball mill. The GMD systems include ringmotors, transformers, E-houses, cyclo converters and a power factor correction and harmonic filter study. Highlight of the scope of supply is the delivery of ABB’s new powerful cylcoconverter controller AC800PEC.
The customer will benefit from the most energy efficient drive solution worldwide for these two milling applications.
The Climax mine is located at some 3,500 meters (11,000 feet) above sea level along the Continental Divide which caps the US Rocky Mountains. Discovered in 1879, the site once boasted the nation’s highest settlement and was traveled by many who joined the 19th Century “gold rush” wave.
The deliveries are scheduled to take place at the end of 2008.
