NEW YORK ThyssenKrupp Robins Inc. will supply Xstrata Copper with an overland conveying system for its Las Bambas copper mine in Peru.
The overland belt conveyors, scheduled to start running in 2014, will transport ore from the Las Bambas Mine to the processing plant at a rate of approximately 9,400 tonnes per hour.
The Las Bambas copper mine will produce some 400,000 tons of copper in concentrate per year by 2015, ThyssenKrupp Robins said.
The gearless drive offers a number of advantages, including the elimination of a series of mechanical and electrical components that increases the efficiency by up to 4 percent, according to the company.
Using gearless drives rather than the standard motor-reducer packages removes around 40 bearings and eight couplings per conveyor, and offers cost savings, Greenwood Village, Colo.-based ThyssenKrupp Robins said, estimating that gearbox maintenance can cost 5 percent of the original investment each year.
Siemens AG will supply the gearless drive to ThyssenKrupp Robins, a subsidiary of Essen, Germany-based ThyssenKrupp Fördertechnik GmbH.
