Beschreibung

The demand of a higher mass flow and longer distances is pushing the development of high-strength conveyor belts continuously forward. The development of the belt splice is advancing simultaneously to the progress of the belt, because this represents the weakest point of the whole conveyor belt system. Since more than thirty years the Institute of Transport and Automation Technology examines belt splices on their dynamic fatigue strength according to DIN 22110-3. To be able to keep up with industrial developments, the institute added to its existing two test rigs one newly designed test rig for the investigation of steel cord belts with nominal strength of more than 7,800 N/mm. Including the new test rig, there have been tested around 1,000 conveyor belt specimen for industrial projects. Within those tests it is clearly stated that in the area of conveyor belt splices the relative fatigue strength is also increasing. This is of great economic relevance, because of the increase in splice strength, the conveying distance and the mass flow can be raised, at the same time as the conveyor belt size can stay the same.
