摘　　要：离心分离法处理微细粒级金属矿物可获得优良的分离指标,但传统离心机存在作业时间断给排矿、设备处理能力低等不足,限制了其广泛应用。针对微细粒级铁矿物回收,研制了一种工业用SLon-1600 mm×900 mm水射流连续式离心选矿机,用于从东鞍山烧结厂选矿车间抛弃的难选铁矿石中分离回收细粒级铁矿物,并进行了工业试验,获得了较好的分离指标。采用该工业试验结果分析了射流喷角、射流压力对水射流连续卸料效果的影响以及射流频率和离心转速对离心分离效果的影响。The treatment of microfine metal minerals by centrifugal separation can achieve good separation performante. However, the intermittent feeding and discharging and low capacity of the conventional centrifugal separators have restricted the wide application in recovering microfine minerals. Therefore, a SLon-1 600 mm× 900 mm water jetting continuous centrifugal separator of industrial scale has been developed for recovering microfine iron minerals from the discarded refractory iron ore in Anshan Concentrator and good separation performances have been achieved. Its industrial test results are used to analyze the effect of jetting angle and pressure on the water jet-assisted continuous discharging and the effect of jetting frequency and centrifugal rotation speed on the separation results.
