SLon磁选机在调军台选厂改造前后工艺中的应用

Application of SLon Magnetic Separators in Diaojuntai Concentrator Before and After Its Process Transformation

调军台选矿厂在原来采用的连续磨矿—弱磁—中磁—强磁—反浮选流程中以15台SLon-2000强磁选机取代Shp-3200平环强磁选机,在改造后采用的阶段磨矿、粗粒细分选的重选—磁选—阴离子反浮选流程中分别以15台SLon-2000强磁机和15台SLon-2000中磁机作为脱泥抛尾设备和粗粒抛尾设备。这些SLon磁选机在减少细粒金属流失、提高金属回收率、为反浮选作业创造良好入选条件、减少中矿再磨量等方面发挥了重要作用,为调军台选矿厂不断取得优异生产指标提供了保障。

Diaojuntai Concentrator used 15 SLon-2000 high intensity magnetic separators to replace the Shp-3200 fiatring high intensity magnetic separators in its original process composed of continuous grinding-low intensity magnetic separation, high intensity separation and reverse flotation. After the technical transformation, the process consisting of staged grinding, coarse and fine size-classified separation by gravity separation, magnetic separation and anionic reverse flotation uses 15 SLon-2000 high intensity magnetic separators and 15 SLon-2000 medium intensity magnetic separators for tailing discarding by desliming and at coarse size respectively. These SLon magnetic separators have played an important role in reducing fine metal loss, improve metal recovery, creating a good condition for reverse flotation and reducing middling regrinding load, thereby providing guarantee for the a continuous achievement of excellent production performance of Diaojuntai Concentrator.
