摘要
新研制的GHC1545 永磁筒式磁选机筒体直径1500 mm,筒体长度4500 mm,采用不同结构的复合磁极组和多梯度挤压磁系结构,磁包角140°,平均磁感应强度180 mT,矿浆通过量可达600～1000 m3/h.在弓长岭选矿厂一选车间的工业试验表明,单台GHC1545磁选机能够匹配MQY5067溢流型球磨机274 t/h的干矿处理量,而且在铁精矿晶位相近的情况下,回收率比现场其他系列所用CTB1232磁选机的回收率提高1.97个百分点.
Abstract
GHC1545 permanent magnet drum separator with drum body's diameter of 1 500 mm and length of 4 500 mm was newly developed, which adopted the compound magnetic poles with different structure and multi-gradient extruded magnetic system. Its magnetic angle is 140° , the average intensity of magnetic field is 180 mT and the flow capacity of slurry is 600 ～ l 000 m3/h. In Gongchangling dressing plant, the industrial experiments in the first workshop showed that single GHC1545 magnetic separator can match the handling capacity of 274 t/h of MQY5067 overflow ball mill for dry ores.Under the condition of iron concentrate in the same grade, the recovery of iron concentrate was increased by l. 97％ than that of other series CTB1232 magnetic separators.
