为了解决红矿(赤铁矿)与青矿(磁铁矿)伴生矿石的选取,提高精矿回收率,鞍钢弓长岭铁矿采用了磁-重选的新工艺。磁选采用筒式永磁磁选机,重选采用离心选矿机选矿。重选车间共装设720台离心选矿机,分四个生产系统。每台离心选矿机上有三个电磁铁,分别按时间原则执行选矿(断矿)、冲水、分矿等周期性的动作过程。这些按时间原则的动
In order to solve the selection of ore associated with red ore (hematite) and green ore (magnetite) and improve the recovery rate of concentrate, Angang Gongchangling Iron Ore adopted a new magnetic re-election process. Magnetic separation using cylindrical permanent magnetic separator, re-election centrifugal concentrator beneficiation. Re-election of the workshop a total of 720 sets of centrifugal concentrator, divided into four production systems. Each centrifugal concentrator has three electromagnets, respectively, according to the timing of the implementation of beneficiation (broken ore), flushing, sub-ore and other cyclical action process. These moves by time
