The need for reliable and robust grinding solutions is driving the development of new technologies able to cope with larger equipment generating higher throughput. If in the past single pinion mills were enough to process all material, today dual pinion or gearless driven mills are necessary. Not only the mill equipment was adapted to exceed its technical and performance limits. Also, the ...
11/07/2013 GE’s Quadramatic™ motor system has one of the highest efficiency levels for dual-pinion, fixed-speed mill applications. Compared to induction or gearless technologies, a 9,000-horsepower (HP) Quadramatic motor system consumes approximately 4.5 million kilowatts (kWh) less electricity per year, avoiding the emissions of approximately 2,700 metric tons of CO 2 on the U.S. grid. This is ...

dual pinion solutions were developed to power the mills. However, realization of the dual pinion solution was only possible when load could be evenly shared between the two pinions. When mill diameter and mill power became again increased, only the Gearless Mill Drive (GMD) could be envisaged to cover this requirement above 10 MW. The GMD is by ...
Pinion mill drives are widely used in the mining industry to grind materials to a requested size. If the equipment is operating at optimum efficiency, this has positive impact on production and operating economics. Drive solutions are needed for speed and torque control. Among the resulting operational benefits, longer maintenance intervals and lower energy costs are the most important. Mining ...
Developed by the ABB minerals unit, the ring-geared mill drive solutions feature a dedicated integrated mill controller, permitting smooth starts and controlled stops, and reducing stress on mechanical components.
