A Gearless Mill Drive (GMD) is a major investment for a plant, and a host of processes are dependent on its reliable performance. This makes its potential downtime one of the biggest risks any mining company faces. It's also one that can be mitigated and controlled through data and insights. Maximize availability and productivity
The ABB gearless mill drive (GMD) is the most powerful mill drive system available, combining the highest levels of efficiency, reliability, flexibility and availability. 3 Competence in grinding For many decades, ABB's optimized mill drive solutions have consistently set new productivity
The gearless mill drive business is an important market for ABB. GMD end users from 20 different mines or cement plants, coming from all five continents, as well as major mill suppliers, accepted ABB's invitation and came to Switzerland to share their knowledge, experiences, problems and ideas with representatives from ABB.
ABB is buying Alstom's ring motor business to enhance its gearless mill drive (GMD) activities. The business, based in Bilbao, Spain, has about 120 employees and achieved a turnover of €57m in 2012/13. It will become part of ABB's Process Automation division. The financial details of the deal have not been revealed.
The company selected ABB's 26 MW gearless mill drive system (GMD) for the mine's 40 ft SAG mill, as well as other drives, electrical infrastructure equipment and a long-term service agreement (LTSA). This is expected to reduce operating costs, improve process throughput and reliability while saving energy and keep equipment in top form.
