Eddy current sorter is a kind of equipment that realizes material classification and separation by using eddy current effect. It induces eddy current in the conductor material through alternating magnetic field, and realizes the separation of materials with different conductive properties by using the interaction between the reverse electromagnetic field generated by eddy current and the primary magnetic field. The equipment is widely used in waste recycling, metal recycling and other fields. The working principle of the eddy current sorter is based on the eddy current effect. The eddy current sorter uses an electromagnet to generate an alternating magnetic field, the frequency and strength of which can be adjusted according to different application requirements. The sensor is mounted on the workbench and is used to detect the eddy current generated by the material. The sensor sends the detected signal to the control system for processing. The control system classifies and separates the materials according to the signals from the sensors. According to the strength and characteristics of the eddy current, the control system can determine the types of different materials and separate them through the appropriate device. The separated material is collected into the appropriate container for subsequent processing and utilization.
