10PCB Overband Magnets

Commonly used worldwide mounted on machinery for the separation and upgrading of materials including plastics, wood, rubber, glass, computer components and aggregate.

The principal of operation is simple:

Conveyor belt revolves continuously around a permanent or electromagnet. The product on the main conveyor or feeder passes under the overband and tramp metals are lifted clear by the magnet.

The metals are then swept out of the magnetic field by the cleated conveyor belt and discharged at a point either parallel to, or at right angles to the side of the conveyed product. Ideally the overband will be positioned in-line as the material being conveyed will be in virtual suspension and “dwell time” under the magnet is optimum.

Due to space restrictions within plant, overbands are commonly fitted across the conveyor, so overband magnets are manufactured in-line and cross-belt to suit customer requirements.
