VDMA 30 VDMA MINING SUPPLEMENT • 2018 Once those primary earthmovers extract coal and ore from the face, it must be moved to its final destination, which could be a miner- al processing plant, a power plant or another transloading facility. For years, the solution to moving more materials was simply larger systems with longer and wider conveyors and more horsepower. The problem, however, is that if the system is fully loaded and pushed to the limit, it could take the entire operation down when it fails. By monitoring and actively managing the material handling system, mines can not only avoid mishaps, such as broken belts and drive slippage, but reduce the tension and horsepower the sys- tem demands. This in turn would allow engineers to specify low- er-rated belting and hardware, reducing overall capital costs as well as energy consumption. Intelligent Drive Solutions Voith traces its roots back to 1867, where it was founded in Heiden- heim, Germany. The company began supplying heavy equipment to the paper industry. In 1870, it began producing water turbines and has been involved in many major hydroelectric projects ever since. Gearbox construction began in 1929, based on the hydrodynamic power transmission, which was invented by Hermann Föttinger. Voith then developed its first fluid couplings. A fluid coupling facto- ry was established in Crailsheim, Germany, in 1956, and is still the headquarters for fluid couplings today. Last year, Voith founded a digital solutions group to accelerate the digital revolution. For mining applications, Voith provides intelligent-drive com- ponents, which can operate in innovative, automated networks. The company's fluid coupling systems are well-known and extreme- ly robust, this ensures safe and reliable operation even in harsh environments. The company recently introduced the TurboBelt 500 TPXL fluid coupling, which combines the fill-controlled advantages of hydro- dynamic drives with intelligent control technology. With cascading speeds and torque control software, it offers smooth conveyor oper- ations for conveyors operating under any conditions. This controlla- bility extends the belt life and eliminates downtime. For steep inclines or long overland conveyors, the company also offers a TT linear booster drive, which increases the drive power and reduces tension forces within the conveyor significantly. By lowering conveyor system's effective tension, engineers can reduce the cost of the belting and structure by as much as 20%, according to Voith. Voith's latest offering, the TurboBelt DriveControl system, could serve as the core for the operational data for modern conveyor net- works. It controls the conveyor behavior and features several capa- bilities, such as self-diagnostics, condition monitoring as well as active-load balancing. "Everything comes together with the control system collecting data from the conveyors and the drive components," said Maike Bechtel, business developer for drive technologies, Voith. "Miners not only want to know how the couplings are running, but also how the belt is driven as far as operational data, load conditions and run times. For this, we have developed a controller with a simplified interface." Voith has found new ways of combining its products with a logical control system, explained Helmut Fleuchaus, business de- velopment manager, Voith. "The control system monitors the torque during startup and operations," Fleuchaus said. "The difference is that we have combined everything into one main unit." Modern high-capacity conveyor systems can be large and com- plex with multiple drives using multiples motors. "Beyond load-bal- Moving More Material, More Effectively The use of intelligent, variable-speed systems help miners reduce transportation costs Voith's latest offering, the TurboBelt DriveControl system (above), could serve as the core for the operational data for modern conveyor networks.
