The eddy current separator is used to recover conductive non-ferrous metals, such as aluminum, copper, zinc and brass, from suitable non-conductive materials after crushing, screening and ferrous metal removal.
During operation, prepared material is evenly fed onto the conveyor belt. A high-speed magnetic rotor generates an alternating magnetic field, inducing eddy currents in conductive non-ferrous metals. The resulting repulsive force changes their discharge trajectory and separates them from materials such as plastic, rubber, glass and other non-conductive residues.
Before eddy current separation, a magnetic separator is normally used to remove iron, steel and other ferrous materials from the processed stream. Screening or a vibrating feeder may also be required to control particle size, spread the material evenly and reduce excessive feeding thickness.
The equipment can be integrated with a scrap metal crusher, twin shaft shredder, conveyors, screening equipment and other recycling machinery. The complete process is configured according to the incoming material, particle size distribution, required capacity and target recovered products.
An eddy current separator does not normally separate mixed aluminum, copper and zinc into individual high-purity products. When separate metal fractions are required, additional density separation, sensor-based sorting, manual sorting or other specialized equipment may be needed.
Separation performance depends on material conductivity, density, particle size, shape, moisture, feeding thickness, belt speed, magnetic rotor configuration and splitter adjustment. Representative material testing is recommended when a specific recovery result is required.
In some Chinese recycling markets, an eddy current separator is also commonly referred to as an aluminum sorting machine or “aluminum jumping separator.”

An eddy current separator works through electromagnetic induction. It is mainly used to recover conductive non-ferrous metals from suitable non-conductive material streams after crushing, screening and ferrous metal removal.
During operation, mixed material is spread evenly across the conveyor belt. When the material passes over the high-speed magnetic rotor, the alternating magnetic field induces eddy currents in conductive metal particles.
The induced currents generate a repulsive force that changes the discharge trajectory of conductive non-ferrous metals. Non-conductive materials, such as plastic, rubber and glass, follow a different trajectory and are collected separately.
During operation, mixed materials are evenly fed onto the conveyor belt. When the material passes over the high-speed magnetic rotor, the rotating magnetic field induces eddy currents in conductive non-ferrous metals. These induced currents create a repulsive force, pushing non-ferrous metals forward and separating them from non-conductive materials such as plastics, rubber, glass and other impurities.
The separation effect depends on material conductivity, density, particle size, feeding thickness, belt speed and magnetic rotor configuration. For better sorting performance, the material should usually be spread evenly on the belt before entering the separation area.
An eddy current separator usually consists of a magnetic rotor, conveyor belt, drive roller, motor, frame, protective cover and electric control cabinet. It can be used together with crushers, shredders, vibrating feeders, magnetic separators, conveyors and other recycling equipment.
Separation of non-ferrous metals: The eddy current separator recovers aluminum, copper-containing particles, zinc, brass and other conductive non-ferrous metals from suitable non-conductive material streams. It is commonly installed after crushing, screening and ferrous metal removal.
Suitable for mixed recycling materials: The equipment can be used for processing crushed aluminum scrap, waste household appliances, automotive shredder residue, electronic waste, aluminum-plastic mixtures, packaging waste and other mixed material streams.
Adjustable separation process: The separation effect can be adjusted by belt speed, rotor speed, material feeding thickness and splitter position. The equipment configuration can be selected according to material size, material composition and sorting requirements.
Continuous automatic operation: The eddy current separator can work continuously with feeding conveyors, vibrating feeders, magnetic separators and discharge conveyors. It is suitable for recycling lines that require continuous material separation.
Permanent magnetic rotor: The magnetic rotor uses permanent magnets to generate a high-speed alternating magnetic field. The rotor structure, magnetic strength and belt width can be selected according to capacity and material requirements.
Easy integration with recycling lines: The separator can be connected with metal shredders, scrap steel crushers, aluminum recycling lines, magnetic separators, screens, conveyors and dust collection systems to form a complete sorting process.
Maintenance-friendly structure: The main maintenance work includes checking the conveyor belt, bearings, motor, rotor, protective cover and electrical components. The structure is designed for easy inspection and routine maintenance.
Separation effect depends on material condition: The final sorting result depends on particle size, feeding thickness, belt speed, material conductivity, density and rotor configuration. Proper feeding and material spreading help improve separation stability.

Find common questions about scrap metal crushers, shredders, recycling lines, equipment selection, capacity configuration and operation requirements.
The right model should be selected according to material type, particle size, moisture content, required capacity, belt width, feeding uniformity, and target non-ferrous metal recovery rate. If the separator is used in a complete recycling line, it should match the shredder, crusher, screen, magnetic separator, conveyors, and control system.
An eddy current separator is usually installed after shredding, crushing, screening, and magnetic separation. The magnetic separator removes ferrous metals first, and then the eddy current separator recovers non-ferrous metals such as aluminum and copper from the remaining materials.
Yes. High moisture, mud, oil, or sticky materials can reduce the separation accuracy of an eddy current separator. For better recovery of aluminum and copper, the material should be as dry and loose as possible before separation.
The suitable material size depends on the machine model, belt width, rotor speed, and separation requirement. In general, materials should be evenly fed and not too large or too fine. For better separation, the material should be pre-shredded, screened, and spread evenly on the belt before entering the eddy current separator.
The shredder mainly reduces material size and does not complete fine metal sorting by itself. Ferrous metals are usually removed by a magnetic separator after shredding, while aluminum and copper can be recovered by an eddy current separator after the material is screened and evenly fed.
Yes. This is an eddy current separator. The separation effect and capacity depend on material size, moisture, belt width, feeding uniformity, and equipment model. Typical capacities may range from about 0.6 to 15 tons per hour.
An eddy current separator is used to recover non-ferrous metals such as aluminum and copper from non-metallic or mixed materials after shredding, crushing, screening, and magnetic separation. It is commonly used in scrap metal recycling, aluminum recycling, solid waste sorting, and electronic waste recycling lines.
Yes. Eddy current separators can be customized by belt width, rotor speed, magnetic roller structure, material size, feeding layer thickness, and required capacity. Common belt widths may range from about 600 mm to 1500 mm, and the final model should match the upstream crusher or screen.
Yes. Production videos and case references can be provided. If necessary, customers can also visit a working site to check the separation effect and equipment performance before purchasing.
An eddy current separator is mainly used to separate non-ferrous metals such as aluminum and copper from non-metallic materials. Stainless steel separation usually requires other sorting equipment, depending on the material mixture.
