Suspended Electromagnets
Suspended Electromagnets
The Suspended Electromagnet provides tramp metal collection from conveyed materials. The electromagnet is typically mounted or suspended over a conveyor belt to remove large pieces of tramp metal that represent a hazard to downstream crushers, mills, pulverizers and grinders. Suspended electromagnets also remove sharp metal that can damage or tear expensive conveyor belts, especially at transfer points. Product purity is enhanced with the separation power of the suspended electromagnet.

Manual Cleaning Models
All MC models are cleaned of accumulated tramp iron by manually transporting the magnet to a dump location and turning off the power. MC models are recommended for material flows with low concentrations of iron or work-hardened stainless steel.
Self Cleaning Models
SC models provide completely automatic tramp metal removal. This system features a short rubber conveyor belt built around the magnet’s face — with a rugged continuous channel frame, bearings, adjustable take-ups, and a shaft-mounted reducer coupled to a Totally Enclosed Fan-Cooled (TEFC) motor.
Series 7000 Suspended Electromagnets
With thousands in place around the globe, Eriez’ most popular suspended magnet model is the SE-7000. Designed to remove damaging tramp metals transported on conveyor systems. They enhance product quality and protect downstream equipment like crushers, mills, and shredders.
By removing sharp metal fragments, they also reduce the risk of tears in high-value conveyor belts. This protection provides for minimal downtime, lower maintenance costs, and an extended lifespan for processing equipment.
Magnet Design
Eriez oil-filled convection-cooled Suspended Electromagnets are engineered to deliver the magnetic strength required to extract large ferrous contaminants from heavy burden depths. From loader bucket teeth to drill bits and rods, these magnets are built to perform in demanding environments.
Each unit is precisely sized based on belt width, speed, burden depth, and material type to ensure optimal tramp iron removal. The magnetic circuit is formed by tightly wound, insulated wire coils around a solid steel core, enclosed in a rugged steel housing. Eriez streamlined coil designs favor more wire and lower power to reduce heat buildup, extend insulation life, and enhance magnetic field strength.
Features:
- Oil-filled and convection-cooled for reliable 24/7 operation — even in the harshest industrial environments — without the need for external cooling
- Exclusive External Expansion Tank designed to maintain coil integrity by regulating oil levels and preventing moisture intrusion
- Insulated aluminium coils with non-degradable spaces and insulation to ensure optimal performance and extended service life
- Manual and self-cleaning options to continuously discharge tramp metal
- Five-Year Coil Warranty for industry-leading protection and long-term peace of mind
- Custom options including turnbuckles, coolants, speed switches, hazardous-rated components, guards, belting, motors, and component monitoring
Compact Force-Cooled Suspended Electromagnets
Eriez provides significantly smaller sized compact force-cooled magnets that are able to provide the same strength as our largest magnets. The key is using a lightweight, active cooling system which can be fully integrated or located remotely.
In applications involving exposure to high ambient temperatures, Eriez optimises the performance of an oil-cooled magnet assembly by recirculating the coolant through a heat exchanger. This improves heat dissipation and increases magnet strength in a much smaller footprint.

- Limestone
- Sand
- Gravel
- Municipal waste
- Wood products
- Recycled materials
- Copper ore
- Other ores
Features
- Higher magnetic fields in a smaller footprint
- Forced cooling allows the magnets to produce a higher field strength at lower temperatures

Chute Suspended Electromagnets
Eriez’ SE-2400 Chute Electromagnets are engineered to remove damaging tramp metals from material streams flowing through chutes or discharging from conveyors.
Each unit is custom engineered based on chute width, burden depth, and material characteristics to ensure optimal tramp metal removal. The magnetic circuit includes tightly wound, insulated wire coils around a solid steel core, all housed in a rugged, industrial-grade enclosure.
What sets the SE-2400 apart is its enhanced coil design, which increases magnetic field strength and coverage. Its unique stepped face improves separation efficiency for maximum tramp metal retention, ensuring cleaner product flow and better protection for your equipment.

Dry Compact Suspended Electromagnets
Dry Compact Suspended Electromagnets are designed to deliver the magnetic strength necessary without the need for oil-filled magnet housings. These air-cooled units generate minimal internal heat for maximum heat transfer via conduction, eliminating the need for cooling fluids or mechanical systems.
The Dry Compact series features an elongated rectangular core that distributes the magnetic field more uniformly across flat conveyor belts. This enhanced coil and core design boosts field strength and coverage for maximum separation efficiency and equipment protection in both stationary and mobile systems — ideal for high-demand material handling.
