HECs type eddy current metal separator

 1、 Description The physical basis of HECs type eddy current metal separator is based on two important physical phenomena: an alternating magnetic field which changes with time is always accompanied by an alternating electric field; the current carrying conductor produces a magnetic field. Therefore, if the conductor is exposed to the alternating magnetic field or the alternating magnetic field formed by the rotation of the fixed magnetic field, the eddy current perpendicular to the flux of the alternating magnetic field will be generated in the conductor. On the other hand, the mirror image magnetic field caused by the conductor eddy current, which is opposite to the induced magnetic field, produces repulsive force on the conductor. For example, copper, aluminum, etc. will leap forward along its transportation direction due to the repulsive force of the magnetic field, so as to realize the separation from other non-metallic materials and achieve the purpose of separation. The main distinguishing criterion is the ratio value of the material conductivity and density, and the ratio value with high ratio value is lower than that with high ratio value The materials are more easily separated. Separate the conductor from the material. 2、 Scope of application HECs type eddy current metal separator is mainly used to recover copper, aluminum and other non-ferrous metals from domestic waste, industrial waste, electronic waste treatment, glass scraps, waste plastic doors and windows, boiler bottom ash, waste automobile chips. It can be widely used in waste treatment, waste electrical appliances recovery and other environmental protection fields, as well as material treatment and other industries in non-ferrous metal processing industry. Specifically, it mainly refers to the following aspects: ◇ electronic waste treatment (refrigerator disassembly line); ◇ separation of aluminum cans and iron metals; ◇ separation of non-ferrous metals from boiler bottom ash; ◇ separation of aluminum or copper blocks from scrap car chips; ◇ separation of non-ferrous metals from glass chips; ◇ separation of non-ferrous metal impurities (such as plastic recovery line) from some production lines; ◇ Separating non-ferrous metals from the recycling of plastic doors and windows; ◇ separating non-ferrous metals from wood; 3、 Structural composition HECs type eddy current metal separator is composed of the main body of the separator and the control cabinet; the main part mainly consists of the separator assembly, the drive motor, the frame and the cover. The sorting assembly becomes the core part of the equipment, which is composed of permanent magnet drum, material conveying system (including material conveying belt, conveyor belt driving drum and deceleration motor). 4、 Features The magnetic system of HECs eddy current metal separator adopts NN and SS interphase arrangement and high-performance NdFeB as magnetic material, which makes the magnetic field stronger, action gradient larger and separation effect better. ◇ the speed of magnetic roller and the belt speed of separation belt can be adjusted by the frequency conversion speed control device and the position of separation plate according to the volume and conductivity of the selected materials, so as to achieve a better separation effect. The equipment has the advantages of simple operation and high degree of automation. It has the functions of fault alarm, fault indication and fault start and stop, which can protect and repair the equipment in time.
