Electro Overhead Magnet
Self-cleaning electromagnetic separation over the belt — deep ferrous recovery on the heaviest burdens, with field strength you can specify.
The Sherbrooke OEM electro overhead magnet position integrates a severe-duty, self-cleaning electromagnetic separator (Dings ILSC class or equal) suspended over the conveyor. Oil-cooled coils precision-wound in anodized aluminum strap (Class H) generate a deep field that pulls ferrous up through heavy burdens; a continuously running cleated belt sweeps captured metal off the full stainless steel bottom plate to the side. Power comes from a convection-cooled three-phase solid-state rectifier. Sherbrooke OEM engineers the mounting position, suspension structure, splitter chutes, and belt protection — including stainless armor cladding for the magnet belt on aggressive C&D duty.
Where It Fits
- Ferrous recovery after the manual A-line on C&D systems — one of the two real options for that position, alongside the drum magnet
- Deep-burden streams where field depth decides recovery
- Scrap and MSW lines pulling steel ahead of fragile equipment like eddy current separators

Electro Overhead Magnet — Frequently Asked Questions
Electro or permanent overhead — how do you choose?
Electro gives a deeper, stronger, specifiable field — it wins on deep burdens, wide belts, and severe duty, at the cost of a rectifier and power draw. Permanent needs no power supply and less maintenance — it wins on moderate burdens and lighter streams. The material profile and working distance make the call at pre-design.
Why not just use a magnetic head pulley instead?
At the high-burden positions — like after the A-line on a C&D system — a head pulley magnet would get overloaded: it has no self-cleaning belt and everything passes directly over it. A drum magnet or an overhead are the only two real options there. Magnetic head pulleys still serve well as polishing steps on lighter, downstream fractions.
How do you protect the magnet belt on C&D duty?
Captured rebar and sharp steel hammer the cleaning belt from underneath. We offer stainless steel armor cladding on the magnet belt — effectively armoring it — which dramatically extends belt life on aggressive streams. The Knowledge Hub article linked on this page covers the details.
