Eddy Current Separator (ECS)

Eddy Current Separator (ECS)

---

Eddy current separators, designed for new recycling industry, purify large bulk streams and separate non-ferrous metals for reuse from recycling. In recycling industry, eddy current separators usually cooperate with other sorting equipment to separate high purity and more high quality recycling products.

Eddy current separator is an effective method for recycling non-ferrous metals. It is composed of a conveyor belt system with a rapidly rotating magnetic rotor that creates an induction field by means of magnetic poles. The eddy currents generated by induction field affect the trajectory of non-ferrous metals. This rotation can be either concentric or eccentric. All our eddy current separators are based on centric or eccentric design. Angle setting of the magnetic rotor is done manually. With the refined angle setting it is possible to achieve a high separation yield of the material flow being treated.

Design principle

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. Through the induction of eddy currents and the resulting repelling forces, the alternating magnetic field selectively repels the non–ferrous metals and physically separates them from other materials with minimum product loss.

Characteristics and advantages

• All eddy current separators are based on an centric or eccentric design
• Design of magnetic rotor optimized to the application
• High intensity magnet rollers are suitable for small fractions and weakly magnetic non-ferrous particles that are both difficult to separate
• Control cabinet including adjustable speed of rotor and belt
• Optimal combinations with other recycling devices

Optional configuration

• FEM calculation to simulate the deepest magnetic field matrix
• Match different magnetic element design according to actual application
• Multi-magnetic pole design satisfy separation requirement of different particle sizes
• Can set the eccentric angle of the magnetic rotor according to actual needs

Application

Separate aluminum, copper and other non-ferrous metals for products with high purity from materials, municipal solid waste, waste residue, and other recyclable resources.

Material handling

Automotive dismantling lines, wood, glass, plastic, mining plants, scrap metal recycling, metal foundry, waste incineration
