NON-FERROUS METAL RECOVERY
Eddy Current Separators
Recover conductive non-ferrous metals from mixed material streams.
A high-speed magnetic rotor repels aluminum, copper and zinc away from non-conductive material. Bunting offers four configurations for fines, mixed recyclables and general waste streams.
Four ModelsECO, HIC, HIE and HIFE
Particle SizeFrom 1 mm (0.04 in), depending on model
Belt WidthsUp to 2 m (6.6 ft), depending on model

Applications
Eddy current separators recover conductive non-ferrous metals from prepared material streams. Common applications include:
- Metal recycling and shredder residue
- Electronic scrap and shredded battery material
- Granulated plastics and mixed recyclables
- Glass cullet, wood and biomass
- Municipal and commercial waste
- Incineration ash
Remove ferrous material before any eddy current model. Bunting can supply an upstream Rare Earth Drum Magnet to remove ferrous particles, including fines, and help protect the belt and rotor shell. Share feed size, throughput and target metals when discussing your line.

BEYOND THE ROTOR
Built For Your Operation
- Right Fit For Your MaterialFour rotor options help match the machine to your feed size and material mix.
- Fits Your LineModular chutes and custom supports suit new or existing installations.
- Bottle Jack Belt ChangeOn HIE, HIC and ECO, an underframe bottle jack raises the conveyor frame so one technician can change the belt without removing the rotor.

Rotor Designs
Both designs need an even feed and a splitter adjusted for the material.
The process
How The Separator Works
The changing magnetic field induces electrical currents in conductive particles. The resulting repulsive force sends those particles beyond the normal drop path, where an adjustable splitter divides the streams.
1. Present The Feed
A belt conveyor presents a consistent layer of material to the high-speed magnetic rotor.
2. The Rotor Repels Metal
The changing field induces currents in conductive particles, projecting non-ferrous metals forward.
3. The Splitter Divides
An adjustable splitter collects recovered metal separately from the remaining material stream.

Application Review And Equipment Inquiry
Specify Your Eddy Current Separator
Tell us what you process and the non-ferrous metals you need to recover. A Bunting application engineer can review equipment fit, configuration and whether a material trial would help confirm the right model.
Useful Information To Include
- Feed material and particle size range
- Target non-ferrous metals and purity goal
- Throughput and available line space
- Existing upstream ferrous separation
- Drawings or photos of the installation
- Facility location and project timing
To compare proposals, request a configuration-specific drawing and specification sheet that state the expected throughput for your feed, electrical requirements, service clearance and test assumptions.

Eddy Current Separator Questions
What Metals Can An Eddy Current Separator Recover?
It separates conductive non-ferrous metals such as aluminum, copper and zinc from non-conductive material. Ferrous metal is typically removed upstream with magnetic separation.
Should Ferrous Metal Be Removed First?
Yes. Ferrous particles, particularly fines, should be removed first because they can damage the belt and rotor shell. Bunting can supply an upstream Rare Earth Drum Magnet with any of the four models. Share your existing separation steps when discussing the line.
How Do I Choose Between HIFE, HIE, HIC And ECO?
Start with particle size, conductivity, feed rate, material presentation and the recovered-metal purity you need. HIFE and HIE target finer fractions; HIC and ECO suit coarser mixed streams. Bunting can confirm fit with your material.
Can The Separator Fit Into An Existing Line?
Yes. Belt widths, chutes, support structures and upstream ferrous separation can be configured for new or existing lines. Share layout and throughput details during selection.
Can Bunting Test My Material?
Bunting offers laboratory-scale trials at its UK Recycling Test Facility. Contact the application team to confirm sample requirements and availability.
