The working principle of the eddy current separator is roughly the same as the structural principle, the structural principle is reflected in the internal structure of the separator, under the premise of this structure, the sorting effect can be produced, the working principle is mainly reflected in the actual production work of the eddy current separator, through which principles can achieve the purpose of non-ferrous metal non-metallic separation. According to many years of experience in production and maintenance of eddy current separator, Suzhou Dingjiahe Automation Equipment Co., Ltd. has carried out a detailed sorting of the working principle and structural principle of the separator.

Eddy current sorting technology is a new type of sorting technology, mainly the use of magnets in accordance with a specific arrangement of the combination of strong magnetic mix. When the material on the sorting belt uniformly passes through the high-speed rotating magnetic field alternating region at a certain speed, the high-conductivity non-ferrous metals (copper, aluminum, magnesium, zinc) in the material. The surface of a non-ferrous metal produces a vortex-electric reaction (law of electromagnetic induction). The vortex of the automatic selector itself will produce a magnetic field in the opposite direction of the original magnetic field. According to the same magnetic repulsion (Lorentz force), the non-ferrous material will get the relative direction of motion and the upward position of the elastic force, which is separated from non-metallic materials such as plastics with low electrical conductivity. Under the action of the initial velocity of non-ferrous metals, the transverse distance of the parabola is relatively far.

The structure principle of the eddy current sorting machine is described in detail: The strong magnetic field eddy current separator is a different separation technology using the magnetic induction intensity generated by the conductivity of various substances. Based on the drum rotation of a high-speed magnetic system composed of permanent magnets, the magnetic field with alternating changes is generated. The conductive metal induces eddy currents in the metal when passing through the magnetic field. The eddy current itself produces an alternating magnetic field that is the same as the induced mirror magnetic field, and the opposite for non-ferrous materials.
