摘要: SCTφ4.5 m磁力脱水槽采用多层环型磁系,磁场分布合理,更有利于磁性矿物的磁团聚,从而提高对磁性矿物的回收能力。同时这种磁系还可以根据实际情况调整磁环层数,满足大型化设计的需要。在鞍钢集团矿业公司大孤山选矿厂的工业试验结果表明:SCTφ4.5 m磁力脱水槽的干矿处理量是现场生产用SCTφ3 m常规磁力脱水槽的2.33倍;在相同的给矿条件下,SCTφ4.5 m磁力脱水槽的精矿品位、尾矿品位及磁性铁损失率等指标均优于φ3 m磁力脱水槽,且SCTφ4.5 m磁力脱水槽比φ3 m脱水槽更容易适应给矿条件的变化。因此,SCTφ4.5 m磁力脱水槽具有较好的推广价值

Abstract: SCTφ4.5 m magnetic dewatering tank adopts multi-level ring type magnet system to produce a more rational magnetic field, better facilitating the magnetic agglomeration of magnetic minerals so as to improve the recovery of magnetic minerals. The number of the magnet ring levels of the system can be adjusted to satisfy the need of upsizing design. The industrial test result in Dagushan Concentrator in Mining Co. AnSteel Group indicates that the dry ore throughput of this machine is 2.33 times that of the currently used φ3 m conventional one. At a similar feed, the performances of SCTφ4.5 m magnetic dewatering tank such as concentrate grade, tailing grade and magnetic iron loss are better than those of the latter and what's more, it is more adaptable to the feed condition change. Therefore, it is of good popularization value.
