新型湿式永磁磁选机的磁系采用稀土钕铁硼和优质铁氧体材料,磁系包角138°,采用开放式磁路设计,磁滚筒表面磁场可达700 mT,比原来顺流型磁选机磁场强度提高40%以上。槽体内表面及磁滚筒外表面粘有耐磨层增加耐磨性,入选矿石粒度直径可达20 mm。通过提铁试验表明,本机运行成本低,使用寿命长,处理量大。-0.074 mm原矿在选别试验中,经过一次粗选的精矿品位可达到52.37%,回收率可达到86.3%,而尾矿则降到36.57%,损失率为13.7%,具有良好的经济效益和社会价值。
The new type of permanent magnet magnetic separator magnetic system using rare earth neodymium iron boron and high-quality ferrite materials, magnetic system wrap angle of 138 °, the use of open magnetic circuit design, magnetic drum surface magnetic field up to 700 mT than the original downstream Magnetic separator magnetic field intensity increased by 40%. Trough body surface and the outer surface of the drum with a wear-resistant layer to increase wear resistance, selected ore size diameter of up to 20 mm. Through the iron test showed that the machine running costs low, long life, large capacity. -0.074 mm ore in the sorting test, after a roughing concentrate grade can reach 52.37%, the recovery rate can reach 86.3%, while the tailings dropped to 36.57%, the loss rate of 13.7%, with good economic benefits And social value.
