Siemens supplies the world's biggest gearless conveyor drive system

06.10.2015
  • Gearless drive technology enables the use of a conveyor belt system in Peru with a total installed power of 12,000 kilowatts
  • Extreme availability due to low wear and reduced maintenance
  • Three percent increase in efficiency over conventional drive systems

Siemens supplies the world's biggest gearless conveyor drive system to the Cuajone Mine in Peru which is operated by the Mexican mining company Southern Copper Corporation (SCC). The modernization project will entail the installation of a new gyratory crushing and conveyor system by 2016.

The belt conveyor will replace a railway system currently used to transport the ore out of the mine to the processing plant. The Integrated Drive System (IDS) used to power the world's highest-powered gearless conveyor system with an output totaling 12,000 kilowatts is being supplied by Siemens.

Not only does the gearless drive enable efficiency to be increased by three percent, it also cuts down the necessary maintenance work and associated costs, as wearing parts such as couplings, motor bearings and gearboxes are no longer required.

In mid-2014, Siemens was chosen by ThyssenKrupp to supply the electrical package to the Cuajone Mine in Peru with a contract valued in the double-digit million Euro range. Previously, the ore was transported out of the mine for further processing using a train over a distance of more than six kilometers to the processing plant. The existing railway is now being replaced by an efficient conveyor belt system and a gyratory crusher, for which Siemens is providing the automation system, the power distribution equipment, and the drive system. Alongside conventional drives, Siemens is deploying primarily Integrated Drive Systems (IDS) with gearless drives which offer a high level of availability by dispensing with many of the wear-prone components such as gearboxes, couplings and motor bearings. Gearless drives also enable the use of a continuous conveyor belt, eliminating the need for transfer stations and so reducing susceptibility to faults, cutting out the need for high-intensity maintenance and driving down costs.

The conveyor belt system comprises three individual sections which are equipped by a total of five Integrated Drive Systems. For the largest of the belt sections, Siemens is supplying two gearless drive systems with an output of 6,000 kilowatts each, comprising a low speed synchronous motor and a Sinamics SL150 cycloconverter. The two smaller feed and discharge belts will be driven by two 500 kilowatt low-voltage motors using Sinamics S150 inverters with regenerative feedback capability and one 1200 kilowatt medium-voltage motor. The converters and motors as well as the gearboxes and couplings for these drives are all supplied by Siemens. The automation components as well as the drive and power distribution technology are provided in modular electrical rooms (E-houses).

Siemens is no stranger to the Cuajone Mine facility, where it supplied a drive system for a HPGR (high-pressure grinding roll) system back in 2013. SCC operates mines and metal processing factories in Peru, US and Mexico, including the Toquepala and the Cuajone copper mines in Southern Peru. The company mines and produces copper, molybdenum, selenium, gold and silver and also invests in the exploration and harnessing of mineral deposits in Peru, Mexico and Chile.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
