Eddy Current Separator
GTEK Eddy Current Separator
Introduction
GTEK Eddy Current Separator is an advanced non-ferrous metal sorting unit which is capable of separating clean non-ferrous metals from others.
After various processing stages (such as instance disintegration crushing, classification and magnetic separation), the non-ferrous metal separator helps to recover clean, marketable non-ferrous metal mixtures (ZORBA) containing aluminum, copper, zinc or brass.
The eddy current separator can therefore be used any place where non-ferrous metals can be recovered or separated, for example when processing shredded scrap, demolition waste, municipal solid waste, packaging waste, bottom ashes from waste incineration, aluminium salt slags, e-waste, wood chips, glass or moulding sand.

Eddy Current Separator For Glass Beverage Recycling
Separating Aluminum Caps & Rings From Glass Shards
GTEK designed a recycling project with 8 tons/h capacity, which was sent to the glass bottle recycling facility of a well-known brewery.
GTEK was asked to do a test, by runing the materials that was sent by the client. And through the video, we can see the non-ferrous parts (Aluminum caps and rings) were efficiently removed from the glass shards. The materials were crushered down to 1-3cm, and separating rate of the non-ferrous has reached more than 90%.
Eddy Current Separator For PET Recycling
Separating Aluminum and Ferrous Flakes From PET Flakes
GTEK's High Frequency Eccentric Eddy Current Separator was especially designed for PET flakes recycling industry. With its advanced technology:
- 38 pole rotor design;
- high grade neodymium magnet which can guarantee a 4,500 gauss on the surface of the 2mm belt;
- 3000RPM standard rotor speed;
The separation rate of the non-ferrous flakes of 5-10mm can reach more than 97% after single passing, and more than 98% after second passing.
While in the test of processing -5mm materials, the separation rate can reach 86% after first passing and 97% after second passing.
Non-ferrous Metal Separator For Waste Metal Recycling
Turnkey non-ferrous recycling line in Guangzhou
GTEK has the ability to design and supply a complete recycling line for the waste metals, no matter for shear scrap or shredder scrap, we have standardized recycling line designs, if you want to learn more, please contact us.
In this case, we are dealing with waste metals of 1mm-10cm from shredder residue. The trommel rejects the dust less than 1mm, and devide the rest materials into three size ranges. Then pass througn three eddy current separators.
Eddy Current Separator For WEEE Recycling
Separating Ferrous and Non-Ferrous from PCB and other plastics
Another main application of the eddy current separator. In this case, it is designed for separating the metals attached on the printed circuit boards (PCB).
A feed size of 3-10cm of the shredded WEEE, first pass through two overband magnets and manul picking, the most ferrous metals have been removed. The others send to our ECS for a second ferrous sorting and non-ferrous separation.

GTEK MAGNET® provides free sample testing service.
By sending us a small amount of samples, you can visually see the specific effect of our eddy current separator in processing your materials.
The video shows a customer from a metal recycling industry who sent us 100KG of auto shredder residue (ASR) tailings after separating by other brands of ECS. The content of non-ferrous metals is about 4.4%.
After testing, 4.37kg of non-ferrous metals are separated. Among them, copper wire is the majority, accounting for 20-30%. The sorting efficiency of copper wires with a diameter of more than 0.5mm is over 95%, which can create great value for the customer.

What is Eddy Current Separation?
Eddy current separation is based on the use of a magnetic rotor with alternating polarity, spinning rapidly inside a non-metallic drum driving by a conveyor belt.
Material is feed onto the conveyor belt of the eddy current separator, which moves it across the magnetic rotor where separation occurs.
As non-ferrous metals pass over the drum, the alternating magnetic field creates eddy current in the non-ferrous metal particles. The generation of eddy currents will cause a magnetic field inside the material, which repels the alternating magnetic field of the rotor, and repelling the material away form the the conveyor. While other materials drop off at the end of conveyor, the non-ferrous metals are propelled forward over a splitter for separation.
How Does an Eddy Current Separator Work?
An Eddy Current Separator consists of a fast alternating magnetic field (composed of a rotor covered with rare-earth magnetic materials and a rotor motor), a running belt, a feed system and a adjustable splitter device.
The magnetic rotor, which is positioned inside the non-conductive outer drum made of special materials, revolves at around 3000 revolutions per minute during operation while the outer drum rotates at belt speed.
The rotation speed of rare-earth magnetic roller generates an induction field, creating a rapid changing magnetic field. The separation is based on the principle that every electrically conductive particle located in an altering magnetic field will be temporarily magnetized. The polarity of that magnetic field is the same as the rotating magnet, causing the conductive particle to be repelled from the magnetic roller, this enable us to separate huge number of non-ferrous material from non-metallic material.
