涡流分选机

 

涡电流分选(Eddy current separationECS)是利用物质电导率不同的一种分选技术,其分选原理基于两个重要的物理现象:一个随时间而变的交变磁场总是伴生一个交变的电场(电磁感应定律);载流导体产生磁场(毕奥一萨伐尔定律)

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,达到分选的目的;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。

 

 

Eddy Sorter

 

Eddy current separation (ECS) is the sorting technology that use the difference of material conductivity, its separation principle is based on two important physical phenomena: a time-varying alternating magnetic field is always associated an alternating electric field (law of electromagnetic induction); current-carrying conductor generates a magnetic field (Biot - Savart Law).

When the device is working, high-frequency alternating magnetic field generated on the surface sorting magnetic roller, the conductive non-ferrous metal through the magnetic field, it will induce eddy current in the non-ferrous metal, and this eddy current will force magenetic field that is opposite of the orginal magenetic field, the non-ferrous metal(as copper, aluminum, etc.) will direction leap forward along the conveying because of the repulsion of the magnetic field, that achieve the separation of other non-metallic substances, and realize the purpose of sorting. It’s main distinguishing criterion is the material conductivity and density ratio value, the higher ratio material is easier to separate than the lower.
