EDDY CURRENT SEPARATOR for Efficient Non-Ferrous Metal Recovery in Recycling
In modern recycling operations, valuable non-ferrous metals are often mixed with plastics, rubber, glass, wood, fluff, ash, and other waste materials. If these metals are not recovered efficiently, recycling plants may lose valuable aluminum, copper, brass, zinc, and other conductive materials in the residue stream. An EDDY CURRENT SEPARATOR is one of the most important machines for improving non-ferrous metal recovery and increasing the value of recycled materials.
CurrenTek provides eddy current separators and complete sorting solutions for recycling plants that need stable, efficient, and reliable separation performance. Our equipment is designed for different recycling applications, including ASR processing, Zorba separation, UBC recycling, plastic recycling, GLASS RECYCLING, IBA treatment, and mixed scrap processing.
What Is an Eddy Current Separator?
An eddy current separator is a recycling machine used to separate 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 head pulley. When conductive metal particles pass through the changing MAGNETic field, eddy currents are generated inside the metal. These eddy currents create a repelling force, causing the non-ferrous metal particles to be ejected forward. Non-conductive materials such as plastic, rubber, glass, and fluff follow a different discharge path.
This separation principle makes the eddy current separator highly effective for recovering valuable non-ferrous metals from complex recycling materials.
Why Eddy Current Separation Matters in Recycling
The value of many recycling streams depends on how much clean and recoverable material can be separated from mixed waste. In many plants, small aluminum pieces, copper wires, brass particles, and other non-ferrous metals can remain trapped in residue if the separation process is not properly designed.
Efficient eddy current separation can help recycling operators:
Recover more aluminum, copper, brass, and zinc
Reduce valuable metal loss in residue
Improve the purity of recovered materials
Increase the value of final products
Reduce manual sorting labor
Improve downstream processing efficiency
Support more stable recycling plant operation
For recycling companies processing high volumes of mixed material, even a small improvement in non-ferrous metal recovery can create meaningful long-term value.
Applications of CurrenTek Eddy Current Separators
CurrenTek eddy current separators can be used in a wide range of recycling applications. Different materials require different process designs, feeding methods, screen sizes, and machine configurations. Choosing the right equipment layout is essential for achieving stable separation results.
ASR Recycling
Auto shredder residue, also known as ASR, contains a complex mixture of plastics, rubber, foam, glass, textiles, ferrous metals, and non-ferrous metals. After magnetic separation removes iron and steel, an eddy current separator can be used to recover aluminum, copper, brass, and other valuable non-ferrous metals from the remaining material stream.
For ASR recycling plants, eddy current separation is an important step for reducing metal loss and improving the value of recovered materials.
Zorba Separation
Zorba is a mixed non-ferrous metal stream that often contains aluminum, copper, brass, zinc, stainless steel, and other materials. Eddy current separators are commonly used in Zorba processing to recover aluminum and other conductive metals from mixed scrap streams.
A stable separation process can help recyclers improve product quality and prepare material for further upgrading.
UBC Recycling
Used beverage cans, or UBC, are an important aluminum recycling material. Eddy current separators can help separate aluminum cans from mixed waste streams, especially when UBC is mixed with plastics, paper, light packaging, or other non-metallic materials.
For UBC recycling, consistent feeding and proper material size control are important for achieving clean aluminum recovery.
Plastic Recycling Metal Separation
Metal contamination is a common problem in plastic recycling. Small pieces of aluminum, copper, and other metals can damage downstream equipment, reduce plastic product quality, and increase processing risk.
CurrenTek eddy current separators can help remove non-ferrous metals from plastic recycling streams. When combined with magnetic separation, the system can remove both ferrous and non-ferrous metal contaminants before further plastic processing.
Glass recycling materials may contain aluminum caps, metal pieces, wires, and other contaminants. Eddy current separation can help remove non-ferrous metals from crushed glass streams, improving material cleanliness and supporting downstream glass recovery.
Incinerator bottom ash, or IBA, often contains valuable metals after waste incineration. Eddy current separators can help recover non-ferrous metals from IBA, including aluminum, copper, and other conductive materials. This process can reduce landfill loss and improve the value of ash treatment operations.
Mixed Scrap Processing
Mixed scrap streams often contain both ferrous and non-ferrous metals, as well as non-metallic materials. A complete sorting process may include feeding, screening, magnetic separation, eddy current separation, and further manual or intelligent sorting. CurrenTek can provide equipment and process recommendations based on the material condition and plant requirements.
Key Factors That Affect Eddy Current Separator Performance
The performance of an eddy current separator is not only determined by the machine itself. The whole process design also affects the final separation result.
Important factors include:
Material size
Material moisture
Feed layer thickness
Feeding stability
Belt speed
Rotor speed
Magnetic rotor design
Splitter position
Previous magnetic separation
Screening before separation
Material composition
For fine materials, stable feeding and proper screening are especially important. If materials are too wet, too sticky, or unevenly distributed on the belt, the separation effect may be reduced. A well-designed sorting system should match the material size, processing capacity, and recovery target of the recycling plant.
Why Magnetic Separation Is Important Before Eddy Current Separation
Before using an eddy current separator, ferrous metals should usually be removed by a MAGNETIC SEPARATOR. This step is important because iron and steel can affect the separation process and may damage downstream equipment.
Magnetic separation helps:
Remove iron and steel from the material stream
Protect the eddy current separator
Reduce contamination
Improve non-ferrous recovery efficiency
Create a cleaner and more stable feed material
For many recycling applications, the best process is not a single machine, but a complete sorting line that combines magnetic separation, screening, and eddy current separation.

A Complete Sorting Solution for Higher Material Value
Recycling plants need more than equipment. They need a reliable process that can turn mixed waste streams into cleaner and higher-value recovered materials. An eddy current separator plays a key role in this process by recovering valuable non-ferrous metals that may otherwise be lost.
For plants processing ASR, Zorba, UBC, plastics, glass, IBA, or mixed scrap, improving non-ferrous metal recovery can directly support better product quality, lower contamination, and stronger recycling returns.
CurrenTek provides eddy current separators, magnetic separators, TROMMEL screens, AI sorting equipment, and complete recycling sorting solutions. With the right equipment combination and process design, recycling operators can improve recovery rate, increase material purity, and create more value from every ton of material.
