ABB has released an in-depth white paper detailing the vital role that gearless grinding technologies can play in driving productivity in mining while simultaneously reducing their carbon footprint.
One of the key findings in the report, based upon extensive testing of ABB’s current installed base of Gearless Mill Drives (GMDs), is the high level of efficiency they provide. GMDs can be up to 3.6 percent more energy efficient than Ring-Geared Mill Drives (RMDs), reducing energy consumption and operational costs of the mine.
This level of efficiency across ABB’s GMD installed base equates to 195 kt of CO2 – the equivalent of 89,000 cars taken off the road. Even a conservative 2 percent of increased efficiency equates to 106 kt of CO2 saved, or 49,000 cars taken off the road. (more…)
