永磁辊筒式强磁选设备的发展

节能降耗一直是磁选技术与装备的重要追求目标,而开放磁系式永磁强磁选是分离弱磁性矿石和非磁性脉石的高效、低成本、绿色技术,强磁永磁化技术发展潜力大、前景好。永磁强磁选设备得到广泛应用的主要有辊式与筒式两种结构形式,对其在弱磁性矿物的块矿干式预选、粗粒湿式预选、微细粒精选及非金属矿提纯等生产工艺流程中的应用情况进行了综述。

Development of Permanent Roll and Drum High-Intensity Magnetic Separators

Energy saving has always been the pursuit of magnetic separation technology and equipment, while the high-intensity permanent magnetic separation with open magnetic system is a efficient, low-cost and green technology in separating weak magnetic minerals from non-magnetic gangues. So high-field permanent magnetization has a good and potential development prospects. Generally, two types of roll and drum high-intensity permanent magnetic separators were widely applied, and their applications in production processing such as lump ore dry preconcentration, coarse ore wet preconcentration, fine particle concentration and nonmetallic ore purification were summarized in this paper.
