对于不同密度的材料的沉—浮分离器,是利用磁流体的悬浮力。这一系统是由一个电磁铁、分选槽、回收设备(对粘附在分离产品上的磁流体回收)及控制系统组成。本文描述了使用永磁铁的沉—浮分离器的结构,并有对有色金属分选的试验结果。在两个分离器中,铁磁体和稀土钴磁体用来作为磁场磁源。一个用来从其它非磁性材料中选出铝,另一个用于铜铅锌的相互分离。对粒度6～30毫米的试样进行了试验,分离器分选效果良好。但由于在磁场中,磁流体里非磁性物料间的吸引力,分离较细的粒度困难。本文还提出了回收粘附于分选产品上的磁流体的化学工艺。
For different density materials Shen-floating separator, the use of magnetic fluid levitation force. The system consists of an electromagnet, a sorting tank, recycling equipment (for recovery of magnetic fluid adhering to separate products), and a control system. This article describes the structure of a permanent-float Shen-float separator with test results for non-ferrous metal sorting. In both separators, ferromagnetic and rare earth cobalt magnets are used as magnetic field sources. One is used to select aluminum from other non-magnetic materials and the other is used to separate copper, lead and zinc from each other. The size of 6 to 30 mm of the sample was tested, the separation separator good results. However, due to the attractiveness of nonmagnetic materials in the magnetic fluid in a magnetic field, separation of finer particles is difficult. Also presented herein is a chemical process for recovering the magnetic fluid adhered to the sorted product.
