An eddy current metal separator, also known as ECS eddy current sorting machine, is an advanced dry sorting device widely used in scrap recycling industries. It targets non-ferrous conductive metals such as aluminum, copper, brass and zinc, separating these valuable metals from plastics, rubber, glass, stone and other non-conductive materials. Unlike magnetic drum separators that capture ferrous steel, eddy current separators rely on electromagnetic repulsion, making them indispensable equipment for auto shredder residue (ASR), e-waste and mixed scrap processing lines.
This machine runs on electromagnetic induction. A high-speed neodymium magnetic rotor inside the conveyor drum generates a rapidly alternating magnetic field. When mixed materials pass over the magnetic zone, conductive non-ferrous metals induce internal eddy currents. These currents build a reverse magnetic field, creating strong repulsive force that changes the metal flight trajectory. Non-metallic materials continue moving forward along the belt, while non-ferrous metals jump into a separate hopper. The splitter plate position, rotor speed and belt speed can be adjusted to match different particle sizes and material conductivity, ensuring stable separation purity.
Our eddy current metal separator brings obvious benefits for recycling operators. First, we adopt high-grade rare earth permanent magnets with stable magnetic performance and low demagnetization rate for long service life. Second, the frequency conversion PLC control system supports flexible parameter adjustment, which helps users handle different particle sizes, from 3mm fine granules to 100mm coarse fragments. Third, the whole structure is sealed and dust-proof, easy to cooperate with dust collection systems. It can be customized in belt width, processing capacity and feeding method to match existing shredding, crushing and magnetic separation equipment. The recovery rate for aluminum and copper can reach high standards for commercial recycling.
Eddy current separators serve multiple recycling workflows. Auto dismantling factories use it to sort aluminum and copper from car shredder residue. E-waste recycling plants recover copper and aluminum from shredded PCB boards and waste cables. Plastic recycling lines remove mixed metal impurities from plastic flakes. It also works for incinerator bottom ash sorting, glass cullet purification and construction waste metal recovery. Normally, it is installed after magnetic separator to remove ferrous metals first, then capture non-ferrous metals, forming a complete metal sorting system.
When purchasing an eddy current metal separator, buyers need to confirm several key factors. First, clarify your raw material type and particle size distribution; fine materials usually need higher rotor frequency. Second, define target hourly throughput, models range from 1 t/h to 20 t/h for selection. Third, check whether your upstream equipment includes shredder, magnetic separator and vibrating feeder to stabilize feeding. Site power, space layout and dust control requirements also matter. Send us your material photos and capacity demand, we can provide matching layout and technical solution.
Q: What is the difference between eddy current separator and magnetic separator?
A: Magnetic separators catch ferrous metals like steel and iron. Eddy current separators repel and recover non-ferrous conductive metals such as aluminum and copper.
Q: Can eddy current separator separate stainless steel?
A: It works for conductive stainless steel fragments, but the separation effect is weaker than aluminum and copper due to lower conductivity.
Q: Can this machine connect to my existing recycling line?
A: Yes, we customize the belt width, frame and feeding inlet to fit your current production line.
