As soon as the system sensors detect a deviation from the set values during their tem- porary measurement, BeltGenius ALEX reports the problem and provides sug- gested solutions to optimize alignment. In first installations, the system greatly reduced idler wear, energy costs, and associated CO2 emissions. Reliable belt conveyor operation is key to productivity in mines. Even small deviations from optimum belt alignment increase energy consump- tion and lead to belt mistracking, with considerable material spillage and downtime. In addition, inaccurate belt alignment increases idler wear. Increased idler wear can also lead to unscheduled downtime and high costs for spare parts. Mine operators can avoid such expenses and production losses using BeltGenius. Voith service employees attach the measuring sensors to the conveyor belt edge on both sides, and these sensors measure the alignment of each individ- ual carrying idler. BeltGenius ALEX digitally measures all data and stores it on an integrated SD card. The sensor system detects exactly which carrying idlers and idler frames are affected and automatically analyzes the origin of the problem. During the process, each individual idler set is measured. The data points from this analysis are listed in a well-organized log that contains specific work instructions. These data points include, among other things, information about which idlers are critical, as well as how big an adjustment must be made, in which direction, and how far. The result of the alignment work will be verified by conducting a second measurement run. The operator then receives the current values of the system along with a direct comparison, including an evaluation of the poten- tially achievable improvements. BeltGenius ALEX has been developed for all conveyor systems with belts thicker than 30 mm. Its high savings potential has been confirmed in an initial pilot run. There were significantly fewer unscheduled downtimes thanks to the sensor-based, high-precision measuring on the con- veyor belt. At the same time, the energy demand for horizontal mate- rial transport fell by more than 10 percent. Following alignment optimi- zation, wear on the carrying idlers also decreased considerably, extending their lifetime by one-fifth in this case. Voith, Rapat Offers Full Line of Enclosed Conveyors Rapat Corp.'s complete line of enclosed conveyors helps eliminate dust emissions, providing a solution for industries looking to meet future silica-related regulations. Perfect for silica sand, the Rapat Series ECTR is an industrial-duty, enclosed-frame conveyor with CEMA troughing and return idlers, which pro- vide increased employee safety, even in the toughest of environments. Features include, toolless top covers, which can easily be removed, and bolt-on bottom covers for a totally enclosed system and a greater ability to control dust. The Rapat Series ETR is a totally enclosed-frame conveyor with CEMA troughing idlers and a self-cleaning UHMW slide belt return. The ETR performs in extreme environments to ensure the capture of dust emis- sions. Also ideal for silica sand and other construction materials, the ETR Series features toolless top covers and inspection doors, which make for easy maintenance. With its self-cleaning UHMW slide belt return and external bearing spool idlers, the Rapat Series RR is the opti- mal solution for moving a wide range of products. Designed to perform in tough environments, the RR series protects the product from weather conditions while capturing dust emissions. Each system is easily customized and built to meet the needs of each specific application. Whether it's limestone, cement or silica sand, Rapat will design and build the exact equipment required for the bulk material being handled to ensure that the job gets done right. "For several years, we've produced enclosed-frame conveyor systems for those companies with a vested interest in being good neighbors in their com- munities or to provide a better work environment for their employees," said Justin Koenig, industrial sales manager for Rapat. "But with possi- ble MSHA regulations on the horizon, companies that need to handle bulk materials must find ways to comply. And we're working to provide the right systems to match any operation."
