ABB

Provisioning variable-speed drive systems as part of SPCC brownfield optimization and expansion projects. For the expansion project, which aims to double the mine’s concentrator milling capacity from 60,000 to 120,000 tons per day, ABB is supplying two 25-foot gearless mill drive systems (GMD) of 15MW.

The GMD systems by removing critical mechanical components like ring-gear, pinion and gearbox, are about 4% more energy efficient than traditional fixed-speed mill drives.
