Overband Electro Magnet Separator
Self-cleaning cross-belt separation for large tramp metal
The Overband Electro Magnet Separator is suspended above a conveyor belt to intercept ferrous tramp metal too large or embedded for a drum separator to reliably catch. An electromagnetic coil generates a powerful field that reaches down through the material bed, lifting nails, bolts, rebar off-cuts, and other tramp metal clear of the product. Most units are self-cleaning: an internal cross-belt continuously carries captured metal to the side of the conveyor and drops it outside the product path, so the line never has to stop for manual clean-out. Suspension height and field strength are matched to burden depth and belt speed at the design stage. This is the standard choice for protecting crushers, shredders, and mills on cement, recycling, and quarry lines where large tramp metal is a real risk to equipment.

Applications
Frequently asked questions
In-line or cross-belt — which do I need?
Cross-belt suits narrow conveyors with side discharge space; in-line suits wider belts where metal is dropped ahead of the burden.
How is suspension height decided
It is calculated from burden depth, belt speed, and expected tramp metal size during the design stage.
Does the unit stop the conveyor to discharge metal?
No, the self-cleaning belt discharges continuously without stopping the main line.
Can this catch metal buried inside the material bed?
Yes, the electromagnet's field is sized to penetrate the full expected burden depth.
