With the surge of waste, recovering non-ferrous metals efficiently is critical. Traditional methods fail to separate non-magnetic metals. To solve this, our Eddy Current Separator was developed. It automatically recycles high-value copper and aluminum from industrial and municipal solid waste, boosting recycling efficiency and sustainability.
This equipment is widely utilized for the fine screening, enrichment, and recovery of various mixed metallic and non-metallic materials:
E-waste Recycling: Recovery of metals from printed circuit boards (PCBs) dismantled from waste household appliances, PCB leftover materials, and circuit board drilling powder waste.
Scrap Wire & Cable Shredding: Separation of miscellaneous wires, waste home appliance dismantling wires, copper-plastic wires, aluminum-plastic wires, fine flexible cables, computer connection wires, automobile/motorcycle battery cables, and automotive wiring harnesses.
Radiator Separation: High-efficiency separation of aluminum and copper from automotive copper-aluminum radiators and air conditioner radiators.
ELV & Appliance Shredded Scrap: Non-ferrous metals recovery from crushed waste appliances such as automobiles and refrigerators, as well as aluminum separation from automobile sealing strips.
Plastic & Waste Sorting: Separation of aluminum-containing substances from PET bottle flakes, aluminum foil separation from PC plastics, aluminum-plastic composite materials, and aluminum extraction from aluminum-plastic doors and windows.
Main Components
The main body of the equipment features a compact design and highly stable operation, primarily consisting of the following components:
Vibrating Feeder: Ensures that mixed materials are evenly and consistently distributed onto the sorting conveyor belt.
Material Conveying System: Includes a durable material conveyor belt, a belt drive drum, and a speed-adjustable reduction motor.
Eddy Current Separating Cylinder: The core separation component, equipped with a high-gradient permanent magnet assembly rotating at high speeds.
Control Cabinet & Protective Cover: Features an integrated intelligent control cabinet and an industrial-grade safety protective cover.
Working Principle
High-Frequency Alternating Magnetic Field: While working, the magnetic roller rotating at high speed produces a high-frequency alternating intense magnetic field on its surface.
Induced Eddy Current: When conductive non-ferrous metals (such as aluminum and copper) pass through this magnetic field, an eddy current is induced inside them.
Opposite Magnetic Repulsion: The induced eddy current itself generates a magnetic field that is opposite to the original magnetic field’s direction.
Precise Leaping Separation: Due to the strong repulsion of the magnetic fields, the non-ferrous metals leap forward along the conveying direction, while non-metallic materials (such as plastics or glass) drop naturally due to gravity, achieving perfect separation.
Wide Particle Size Range: Highly flexible in sorting, capable of separating a wide range of metal particle sizes, typically ranging from 3 mm to 100 mm.
Energy Efficient & Easy Maintenance: Equipped with a high-gradient rare earth permanent magnet system, ensuring exceptionally low energy consumption while maintaining high magnetic intensity, alongside easy routine maintenance.
Precise and Accurate Sorting: Supports different rotor directions, allowing accurate sorting of materials with various particle sizes by fine-tuning the operation parameters.
Customization & Flexible Integration: Can be customized based on specific material types and customer requirements, seamlessly integrating with new or existing crushing and recycling production lines.
Multiple Models Available: Available in various models ranging from ZY400 to ZY1500 , with tray/belt widths from 300 mm to 1500 mm. The processing capacity spans from 2 t/h to 15 t/h, perfectly meeting diverse production scale requirements.
Q1: Are there any preprocessing requirements for materials before entering the eddy current separator?
A: Yes. Before eddy current separation, the materials need to be relatively uniform in size, which is usually achieved by pre-crushing. Our company can provide complete crushing and separation solutions tailored to specific materials and customer requirements.
Q2: How do I determine if my mixed materials are easy to separate using this machine?
A: The main criterion to distinguish is the ratio of material conductivity and density values. Materials with a higher ratio value (such as aluminum and copper) generate a stronger repulsive force in the alternating magnetic field and are much more likely to be separated with high purity.
