Eddy Current Separator is a device that uses the eddy current principle to separate different metal materials. It is widely used in waste material recycling, mineral processing, plastic sorting and other fields, especially in separating non-ferrous metals and other materials.
Working Principle
The eddy current separator generates eddy current through a rotating magnetic field, thereby separating metal materials from non-metallic materials. Its core principles are as follows:
- Magnetic field induction: The rotating magnetic poles in the machine generate a high-speed changing magnetic field. When non-ferromagnetic metals (such as aluminum, copper, zinc, etc.) enter the magnetic field, the metal will generate eddy current.
- Magnetic repulsion: The eddy current in turn generates a reverse magnetic field. This reverse magnetic field interacts with the rotating magnetic field of the machine to generate a repulsive force, causing the metal material to deviate from its original track.
- Separation effect: By adjusting the rotation speed and other parameters of the machine, different types of metals can be separated from other materials.
Application fields
Eddy current separators are mainly used in the following fields:
- Waste material recycling: Separate non-ferrous metals (such as aluminum, copper, etc.) from waste to achieve resource recycling and reuse.
- Plastic separation: Used to separate non-ferrous metal substances from plastic waste and improve the purity of plastics.
- Mineral processing: Separate non-ferrous metal minerals in ore processing.
- Food industry: Separate metal impurities that may be mixed in the food production process.
