Development and Application of SPBC Type Permanent Magnet Plate Magnetic Separator
In order to realize the efficient separation and recovery of feebly magnetic and fine-grained minerals,aiming at the problems of complex structure,high cost,high energy consumption and poor iron re-moval effect of electromagnetic magnetic separators in the current market,an innovative permanent magnet high gradient magnetic separation technology is developed,and a SPBC permanent magnet high gradient plate magnetic separator is designed and developed.The machine makes full use of the high magnetic field intensity generated by the permanent magnet material to provide sufficient magnetic force,and realizes the high magnetization of the equipment by optimizing the magnetic circuit structure.The experimental results show that when the equipment is used to treat garnet,the iron removal rate of one roughing is as high as 95.53%,which significantly improves the purity of the mineral.In the treatment of quartz sand samples,the iron removal rate of one roughing is 46.6%,which effectively removes the iron impurities in the fine fraction.In the separation of ilmenite samples,the recovery rate of titanium in one roughing is 74.45%,which signifi-cantly improves the quality of ilmenite concentrate.The SPBC type permanent magnet plate magnetic separa-tor has the advantages of simple structure,easy installation and maintenance,low energy consumption and low cost.It is not only suitable for iron removal and purification of non-metallic minerals,but also can be ap-plied to the separation of feebly magnetic metal minerals and the recovery of feebly magnetic valuable metals in tailings.It provides an efficient and economical new solution for the field of mineral separation,and has wide application value.
