Siemens expands mining portfolio to include gearless drive system for 42-foot SAG mills

Siemens is now able to provide to mining companies a gearless drive system for SAG mills with a tube diameter of 42 feet. This enables throughput to be almost doubled in comparison with the 38-foot mills commonly used today. With this innovation, Siemens is responding to the rising demand for larger and more powerful drives in mining. The principal component of the new drive system, which was designed and constructed within just two years, is a ring motor with a width of 25 meters and a height of 20 meters.
