Gearless Drives for Overland Conveyors

Product catalog summary
Introduction to Gearless Drives: ThyssenKrupp, in partnership with Siemens, has introduced a new generation of gearless, cycloconverter-fed conveyor drives. These systems are designed to meet high power demands with fewer components, resulting in increased availability, reduced energy consumption, and lower maintenance costs.
Advantages of Gearless Drives: Gearless drive systems eliminate the need for gear reducers, offering a simpler and more robust construction that is easier to maintain. They enhance plant availability by removing electrical components, couplings, gearboxes, and lubrication systems, thus reducing downtime risks. Additionally, they achieve up to four percent higher energy efficiency and lower noise levels by eliminating the loudest parts of conventional drive stations.
Historical Context: The first gearless direct-drive belt conveyor was installed in 1985 at the Prosper-Haniel coal mine in Germany. This system has operated successfully for over 25 years, demonstrating significant maintenance cost savings and energy efficiency compared to traditional geared conveyors.
Case Study - Antapaccay Mine: At Xstrata Copper's Antapaccay mine in Peru, ThyssenKrupp and Siemens are implementing gearless drives. The system features two 3,800 kW low-speed synchronous motors, providing high torque and reliability in remote, mountainous areas. The conveyor is designed to transport 5,263 metric tons per hour over a distance of 6,528 meters.
Converter Technology: Siemens offers two types of converters: the air-cooled SINAMICS SL 150 cycloconverter and the water-cooled SINAMICS SM 150 voltage source converter. Each has distinct benefits, such as high overload capability, high efficiency, and low maintenance requirements. The choice of converter depends on specific operational needs.
Conclusion: As mining operations move to more remote locations with deeper pits and larger underground mines, gearless drive systems are increasingly necessary. These systems offer solutions to the challenges of transporting more material over longer distances while maintaining high availability and minimizing maintenance costs.
Introduction: Traditional conveyor drive systems with gearboxes are reaching their physical limits, especially for systems requiring more than 20,000 kW. Such systems would need multiple drives, leading to reduced availability and increased maintenance challenges, particularly in remote mining locations.
Technological Advancements: Gearless drives, such as the SINAMICS SL 150 cycloconverter, offer high overload capability, efficiency, and reliability with fewer components. These systems are particularly beneficial in remote and challenging environments, providing high torque and operational flexibility.
Benefits of Gearless Drives:
  • Higher plant availability by eliminating mechanical components like gearboxes and couplings.
  • Increased energy efficiency and reduced maintenance costs.
  • Capability to handle higher power requirements with fewer drive stations.
  • Reduced noise levels and lower capital investment due to fewer spare parts.
Conclusion: Gearless drive systems represent a significant advancement in conveyor technology, offering robust, efficient, and low-maintenance solutions for modern mining challenges. The collaboration between Siemens and ThyssenKrupp continues to push the boundaries of material handling capabilities.

Gearless Drives for Overland Conveyors-1

Gearless Drives for conveyors – capable of handling high power requirements and easy to maintain Together with Siemens, ThyssenKrupp has introduced a new highperformance generation of gearless, cycloconverter-fed ­ onveyor c drives. The principle has been proven for more than 25 years, with ongoing research and development. Its advantages are clear to see: fewer components, high ­ vailability, a reduced overall energy consumption, lower maintenance costs. Redefining power for conveyor drives Long conveyors with high throughput and steep height differences require a significant amount of power. When the demand for power exceeds three MW per pulley, Gearless Drive systems are the right solution. This system overcomes the restrictions attributed to gear reducers, and its gearless construction is simple, robust and easy to maintain. Cycloconverter technology has proven its high reliability over several decades. Conveyor belt suppliers are also able now to manufacture stronger belts (ST-10,000) that can withstand higher stresses resulting from higher drive power. In a word: The time to go gearless has come. Fewer components, longer conveyor Fewer high performance drives replacing many conventional ones: This formula makes longer conveyors more feasible and economical. With fewer components, the drive stations require smaller footprints. In underground applications, the number of expensive excavations are minimized. • igher plant availability by eliminating H e ­ lectrical components, couplings, gearboxes, associated bearings and lubrication systems – therefore minimizing the risk of downtime • p to four percent higher energy efficiency U achieved with gearless direct-drive technology • onger conveyors with fewer and smaller L drive stations, resulting in reduced excavations in underground applications ThyssenKrupp Robins, Inc. 6400 South Fiddler’s Green Circle, Suite 700 Greenwood Village, Colorado 80111 USA [email protected] www.thyssenkrupprobins.com ThyssenKrupp Fördertechnik GmbH Business Unit Mining ThyssenKrupp Allee 1 45143 Essen Germany [email protected] www.tk-mining.com Siemens AG Industry Sector Industry Solutions Mining Technologies Schuhstr. 60 91052 Erlangen Germany [email protected] www.siemens.com/mining • igher power at the pulley – free H from traditional gearbox limitations • educe the potential for mechanical breakR downs by using more robust components • ewer spare parts resulting in less inventory F and lower capital investment • eduction of noise levels by eliminating R the reducer, the loudest part of a conventional drive station In cooperation with Siemens Gearless Conveyor Drives Synch.
