渦電流分選機設備回收分選廢鋼破碎料，使用渦電流分選機在工作時(shí)，在分選磁輥表面產(chǎn)生高頻交變的強磁場(chǎng)，當有導電性的有色金屬經(jīng)過(guò)磁場(chǎng)時(shí)，會(huì )在有色金屬內感應出渦電流，此渦電流本身會(huì )產(chǎn)生與原磁場(chǎng)方向相反的磁場(chǎng)，有色金屬（如銅、鋁等）則會(huì )因磁場(chǎng)的排斥力作用而沿其輸送方向向前飛躍，實(shí)現與其它非金屬類(lèi)物質(zhì)的分離。
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.
其主要區分判據是物料導電率和密度的比率值，比率值高的較之比率低的物料更易分離，這樣就實(shí)現了廢鋼破碎料有色金屬的分離提純，得到很好的利用價(jià)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.
從工業(yè)廢料、生活垃圾中分選出銅、鋁等有色金屬?？蓮V泛用于垃圾處理、廢舊汽車(chē)拆解回收、廢舊電器回收等領(lǐng)域，以及有色金屬加工行業(yè)的物料處理等行業(yè)。有色金屬分選機對多種非鐵金屬有良好的分選效果，該機具有適應性強、機械結構可靠、磁場(chǎng)強、頻率可調的特點(diǎn)。根據適應物料性質(zhì)和顆粒大小的不同有同心有色金屬渦流分選機和偏心有色金屬渦流分選機兩種。
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.
渦電流分選機渦流通道的損耗電阻，以及渦流產(chǎn)生的反磁通，又反射到探頭線(xiàn)圈，改變了線(xiàn)圈的電流大小及相位，即改變了線(xiàn)圈的阻抗。因此，探頭在金屬表面移動(dòng)，遇到缺陷或材質(zhì)、尺寸等變化時(shí)，使得渦流磁場(chǎng)對線(xiàn)圈的反作用不同，引起線(xiàn)圈阻抗變化，通過(guò)渦流檢測儀器測量出這種變化量就能鑒別金屬表面有無(wú)缺陷或其它物理性質(zhì)變化。
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.
