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.
