涡电流分选机设备回收分选废钢破碎料，使用涡电流分选机在工作时，在分选磁辊表面产生高频交变的强磁场，当有导电性的有色金属经过磁场时，会在有色金属内感应出涡电流，此涡电流本身会产生与原磁场方向相反的磁场，有色金属（如铜、铝等）则会因磁场的排斥力作用而沿其输送方向向前飞跃，实现与其它非金属类物质的分离。
The eddy current sorting machine equipment recycles and sorts scrap steel and crushed materials. When using the eddy current sorting machine, a high-frequency alternating strong magnetic field is generated on the surface of the sorting magnetic roller during operation. When conductive non-ferrous metals pass through the magnetic field, eddy current is induced inside the non-ferrous metal. This eddy current itself generates a magnetic field opposite to the original magnetic field direction, and non-ferrous metals (such as copper, aluminum, etc.) will leap forward along their conveying direction due to the repulsive force of the magnetic field, Realize separation from other non-metallic substances.
其主要区分判据是物料导电率和密度的比率值，比率值高的较之比率低的物料更易分离，这样就实现了废钢破碎料有色金属的分离提纯，得到很好的利用价值。
The main distinguishing criterion is the ratio value of material conductivity to density. Materials with higher ratio values are easier to separate compared to materials with lower ratio values, thus achieving the separation and purification of non-ferrous metals from scrap crushing materials and achieving good utilization value.
从工业废料、生活垃圾中分选出铜、铝等有色金属。可广泛用于垃圾处理、废旧汽车拆解回收、废旧电器回收等领域，以及有色金属加工行业的物料处理等行业。有色金属分选机对多种非铁金属有良好的分选效果，该机具有适应性强、机械结构可靠、磁场强、频率可调的特点。根据适应物料性质和颗粒大小的不同有同心有色金属涡流分选机和偏心有色金属涡流分选机两种。
Separate non-ferrous metals such as copper and aluminum from industrial waste and household waste. It can be widely used in fields such as garbage treatment, dismantling and recycling of waste cars, recycling of waste electrical appliances, and material handling in the non-ferrous metal processing industry. The non-ferrous metal sorting machine has good sorting performance for various non-ferrous metals. It has the characteristics of strong adaptability, reliable mechanical structure, strong magnetic field, and adjustable frequency. There are two types of non ferrous metal eddy current separators, concentric and eccentric, based on the different properties and particle sizes of the materials.
涡电流分选机涡流通道的损耗电阻，以及涡流产生的反磁通，又反射到探头线圈，改变了线圈的电流大小及相位，即改变了线圈的阻抗。因此，探头在金属表面移动，遇到缺陷或材质、尺寸等变化时，使得涡流磁场对线圈的反作用不同，引起线圈阻抗变化，通过涡流检测仪器测量出这种变化量就能鉴别金属表面有无缺陷或其它物理性质变化。
The loss resistance of the eddy current channel of the eddy current sorting machine, as well as the anti magnetic flux generated by the eddy current, are reflected onto the probe coil, changing the current magnitude and phase of the coil, i.e. changing the impedance of the coil. Therefore, when the probe moves on the metal surface and encounters defects or changes in material, size, etc., the reaction of the eddy current magnetic field on the coil is different, causing changes in the coil impedance. By measuring this change through eddy current testing instruments, it can be determined whether there are defects or other physical changes on the metal surface.
