摘要/Abstract

摘要： 脉动高梯度磁选是分选弱磁性矿物的有效方法之一。目前有垂直磁系和水平磁系脉动高梯度磁选机。通过采用多梯度技术和水气卸矿技术的水平磁系脉动高梯度磁选机在上海梅山选矿厂的试生产试验，结果表明在同等条件下该设备的选别指标达到生产现场垂直磁系脉动高梯度磁选机的选别性能，其长期运行的选别效果变化不大。上海梅山选矿厂在该设备没有更换选别介质盒的情况下，生产运行3个月基本无堵塞，说明该设备设计合理，卸矿方式先进有效。

Abstract: Pulsating high gradient magnetic separation is one of the effective ways to separate weakly magnetic minerals.Presently, there are pulsating high gradient magnetic separators with a vertical or horizontal magnet system.The kind with a horizontal magnet system adopting multi-gradient and air-gas joint discharge techniques was tested in Shanghai Meishan Iron Concentrator.The test results showed that, at the same operation conditions, its performance indexes reached those with a vertical magnet system operating on the production site, which were kept in a long-term operation.It ran for three months on the site of Meishan Concentrator without replacing the medium box, which indicates that this equipment is rationally designed and its ore discharging mode is both advanced and efficient.

Key words: Horizontal magnet system, Multi-gradient, Air-water joint discharge of ore
