摘要
外磁式磁选机是一种新型的磁选设备,通过磁系布置在分选筒外部,实现了筒内吸住式分选,适用于铁矿石预选、尾矿回收等对于金属回收率有较高要求的工艺段。文中介绍了外磁式磁选机的分选原理、结构组成及特点,经工业应用表明,外磁式磁选机可有效实现铁矿石粗颗粒预选作业,单台设备可实现一次粗选、一次扫选作业,配置简单,运行成本低。
External Magnet Separation equipment is a new kind of magnetic separation equipment, which realize the suck sorting inside the shell through the magnet arranged outside. It can be used for iron ore preconcentration and tailings recovery where requiring for higher metal recovery. This paper introduces the sorting principle, structure composition and characteristics of the external magnet separator. The industrial application shows that the external magnetic separator can effectively realize the coarse particle preconcentration of iron ore, and the single equipment can realize the roughing and scavenging operation, configuration is simple with low operating costs.
