In modern recycling plants, valuable non-ferrous metals are often mixed with plastics, rubber, glass, fluff, ash, paper, and other waste materials. If these metals are not separated efficiently, aluminum, copper, brass, zinc, and other valuable materials may remain in the residue stream and reduce the final value of recycled products.
An EDDY CURRENT SEPARATOR is one of the most important machines for non-ferrous metal recovery. It is widely used in ASR recycling, Zorba processing, UBC recycling, plastic recycling, GLASS RECYCLING, IBA treatment, and mixed scrap sorting. For recycling operators, choosing the right eddy current separation system can help improve recovery rate, increase material purity, reduce metal loss, and create more value from every ton of material.
What Is an EDDY CURRENT SEPARATOR?
An eddy current separator is a recycling machine designed to separate conductive non-ferrous metals from non-metallic materials. It is commonly used to recover aluminum, copper, brass, and other conductive metals from mixed waste streams.
The machine uses a high-speed MAGNETic rotor installed inside the conveyor head pulley. When non-ferrous metal particles pass through the changing MAGNETic field, eddy currents are generated inside the conductive metal. These eddy currents create a repelling force, which pushes the metal particles forward into a separate discharge area. Non-conductive materials, such as plastics, rubber, glass, and fluff, follow a different path.
This principle makes eddy current separation an effective solution for recovering valuable non-ferrous metals from complex recycling materials.
Why Non-Ferrous Metal Recovery Matters
Many recycling materials contain small but valuable metal pieces. In ASR, plastics, Zorba, UBC, glass, and IBA, non-ferrous metals may be mixed with different impurities. Without an efficient separation process, these metals can be lost in residue or contaminate the final product.
Efficient non-ferrous metal recovery can help recycling plants:
Recover more aluminum, copper, brass, and zinc
Reduce valuable metal loss
Improve product purity
Increase the value of recovered materials
Reduce manual sorting work
Protect downstream processing equipment
Improve the stability of the recycling line
For high-volume recycling plants, even a small improvement in metal recovery can create significant long-term value.
Applications of Eddy Current Separators
ASR Recycling
Auto shredder residue, also known as ASR, is a complex material stream generated after vehicle shredding and metal recovery. It often contains plastics, rubber, foam, textiles, glass, ferrous metals, stainless steel, wires, and non-ferrous metals.
In an ASR recycling process, magnetic separation is usually used first to remove iron and steel. After that, an eddy current separator can recover aluminum, copper, brass, and other non-ferrous metals from the remaining material stream. This helps reduce metal loss and improve the value of recovered materials.
Zorba Separation
Zorba is a mixed non-ferrous metal stream that may contain aluminum, copper, brass, zinc, stainless steel, and other materials. Eddy current separators are widely used in Zorba processing to separate conductive metals from non-metallic impurities.
For ZORBA RECYCLING plants, stable feeding, proper material size control, and accurate splitter adjustment are important for achieving clean separation and consistent product quality.
UBC Recycling
Used beverage cans, also called UBC, are a valuable aluminum recycling material. Eddy current separators can help recover aluminum cans from mixed waste streams, especially when cans are mixed with plastics, paper, light packaging, or other non-metallic materials.
For UBC recycling, the material should be evenly fed onto the conveyor belt. A stable feed layer helps improve separation accuracy and reduce material carryover.
Plastic Recycling Metal Separation
Metal contamination is a common problem in plastic recycling. Aluminum flakes, copper pieces, wires, and other metal contaminants may be mixed with PET, ABS, PP, PE, and other plastic materials. These contaminants can damage downstream equipment, reduce plastic product quality, and increase processing risk.
A complete plastic recycling separation process often includes magnetic separation and eddy current separation. MAGNETIC SEPARATORs remove iron and steel, while eddy current separators recover aluminum, copper, and other non-ferrous metals from the plastic stream.
In glass recycling, metal caps, aluminum pieces, wires, and other contaminants may remain in crushed glass. Eddy current separation can help remove non-ferrous metals from glass streams, improving material cleanliness and supporting downstream processing.
Incinerator bottom ash, or IBA, often contains valuable metals after waste incineration. Eddy current separators can recover aluminum, copper, and other conductive metals from IBA. This process helps reduce landfill loss and increase the value of ash treatment operations.
Mixed Scrap Processing
Mixed scrap streams often contain ferrous metals, non-ferrous metals, plastics, rubber, glass, and other impurities. A single machine is usually not enough for stable recovery. A complete sorting process may include feeding, screening, magnetic separation, eddy current separation, and additional manual or intelligent sorting.
CurrenTek can provide equipment recommendations based on material type, particle size, processing capacity, and recovery goals.
Why Magnetic Separation Should Come First
Before eddy current separation, ferrous metals should usually be removed by a MAGNETIC SEPARATOR. This step is important because iron and steel can affect downstream separation performance and may cause equipment wear or damage.
Magnetic separation helps:
Remove iron and steel from the material stream
Protect the eddy current separator
Reduce material contamination
Improve non-ferrous recovery efficiency
Create a cleaner and more stable feed material
For many recycling applications, magnetic separation and eddy current separation should work together as part of a complete sorting process.
Key Factors That Affect Eddy Current Separation Performance
The performance of an eddy current separator depends not only on the machine, but also on the complete process design. Different materials require different equipment settings and layouts.
Important factors include:
Material size
Material moisture
Feed layer thickness
Feeding stability
Belt speed
Rotor speed
Magnetic rotor design
Splitter position
Screening before separation
Magnetic separation before eddy current separation
Material composition
For fine materials, stable feeding and proper screening are especially important. If the material is too wet, too sticky, or unevenly distributed on the belt, the separation result may be reduced. A well-designed system should match the material size, capacity, and target recovery requirements of the recycling plant.
