New Concept for Preventive Maintenance of Belt Conveyors
The company, which specialises in optimising belt conveyor systems and is known for its contactless AirScrape skirting for conveyor transfer points.
i In theory, belt conveyors in the mining and quarrying industry are ideal “candidates” for implementing concepts of operating condition monitoring and predictive maintenance. The belts run continuously, the environmental conditions are unfavourable (dust, humidity, day/night temperature changes etc.). There are typical irregularities (skewing, dropping) and also characteristic damage patterns (uneven wear, belt cracks etc.). And the need for continuous condition monitoring is also given – after all, in most cases there is no alternative or redundant system that can quickly take over the task of material transport in the event of a belt stop.
Desire: practical operating condition monitoring
Nevertheless, the solutions for condition monitoring that have been available on the market up to now are, strictly speaking, only partial solutions. The classic is an electromechanical belt-alignment switch with a two-stage signal. If the belt runs off-centre in a defined
