Roller energy supply systems for a composting plant
Since the composting plant was commissioned, energy supply systems in various lengths and designs have been in use in the so-called spiral system. The special feature: With heat, coarse dirt and high humidity, the energy supply system has a tough job. Nevertheless, the plant operator expects a service life of 5 years under these extremely aggressive conditions and is highly satisfied after working with the roller energy chain solution from igus®.
"Although they have been in use for over two years, they have not yet shown any signs of wear. The energy supply systems are checked monthly. Here we can see that no abrasion has been detected so far"
Dipl.-Ing. Werner Kretzinger, Electrical Engineering Maintenance Manager at AVA Abfallverwertung Augsburg GmbH
During an initial visit to the operator, igus® presented its roller energy supply system. Developed for particularly dirty applications, among other things, its advantages were quickly recognised at AVA. "And from the first roller chain to the current model, development has not stood still," emphasises Michael Offner. "The distance between the individual rollers has been shortened and once again adapted to the tough conditions on site." Customer requirements have therefore been incorporated directly into product development.
"We immediately ordered a chain for the next revision," recalls Werner Kretzinger. "And were able to compare the two systems. The technical advantages of the roller energy supply system quickly became apparent to us. Today, we only have one sliding energy chain in use, which will be the last to be replaced next year." AVA Augsburg is certain that the roller energy supply systems in the composting plants will last at least five years. This increases the service life fivefold.
"It's a full-time job to keep the energy supply systems running in this atmosphere," concludes the maintenance manager. "But with the monthly measurements and the annual inspections, we realise that we weren't promised too much." The investment pays off.
