Belt Demagnetisation System is the first permanently installed belt demagnetisation system for steel cord belt.
WHY IS IT NEEDED?
The metal detectors on conveyor belts with steel cords will have a reduced effectiveness if those cords have residual magnetism. The magnetism can cause the conveyor to false trip when theres nothing on the belt or the tramp metal can pass through undetected due to reduced sensitivity to stop false trip events from occurring.
HOW DOES IT WORK?
The belt demagnetisation system is designed to reduce strong pockets of magnetic flux that occur in the splices of steel cord conveyor belts. The system comprises of several conditioning heads placed below the carry side of the belt that normalises, then attenuates the magnetic flux. As the magnetised splices pass over the system the demagnetising process takes place reducing the magnetic flux by 95%
WHY DO STEEL CORD BELTS BECOME MAGNETISED?
The steel cords within the belt can become magnetised by Tramp Metal Magnets, cord scanning equipment or from large electrical currents from drive motors.
