Guarantees reliable operation thanks to rugged threephase motors backed by high-performance automation systems. Our drive controllers minimize wear and tear, increasing the life of mechanical components. A belt speed controller system ensures that the belts are always optimally loaded, providing energy savings of up to 20% depending on the load.
Reliable transport over mile-long routes: the Los Pelambres copper mine in Chile
The ore from the Los Pelambres mine in Chile is mined at a height of up to 3,200 m (10,500 ft) and must then be conveyed over a distance of 12.7 km (nearly 8 miles). This is made possible by a SIMINE CON solution with ten 2,500-kW squirrel-cage motors. Transport of the copper ore from the mine to the concentrator generates approximately 17 MW of electrical power, which is fed back into the plant network. This reduces the production costs for copper concentrate considerably. Additionally the lower conveyor belt tension reduces wear and increases maintenance intervals. At the same time, load-dependent controlling of the conveyor speed cuts power consumption.
