Concentric Pole Eddy Current Separator

The principle is the same as that of eccentric eddy current, and the purpose is different. It is specially designed for THE PET industry to purify and screen impurities for PET flake.


Concentric rotors consist of an alternating pole Rare Earth magnet system, which completely fills the space available within the separation rotor drum.

The magnet system rotates at high speed within a few millimeters of the outer shell surface generating very high ‘eddy currents’ on the surface resulting in very high repulsive forces.


Eddy current separators have a conveyor belt system with a high-speed magnetic rotor at the end. The rotation speed of the magnets generates an induction field, creating a rapidly changing magnetic field. The separation is based on the principle that every electrically conductive particle located in an alternating magnetic field is temporarily magnetized.

Features of our ECS:

Concentric Eddy Current separators For this type, the magnetic rotor is mounted in the middle of the revolving drum. This results in a large separation angle which is desirable for some product types.

This type of separator can easily be used in product flows that are almost or entirely free of iron and only contain non-ferrous metals.

It is more suitable for smaller size particles.

Working widths: 400/650/800/1000/1200/1500 mm

Specific requirements for non-standard applications can naturally always be discussed.
