技术介绍
目前,国内的磁选矿厂普遍采用筒式磁选机、磁力脱泥槽等磁选设备。这类设备的磁场强度较高,磁场力较大,对磁铁矿的选别有强大的磁团聚作用。因此存在“磁性夹杂”和“非磁性夹杂”等先天劣势,使得精矿中含有较多的脉石,严重影响精矿品位。另外,该类磁选设备工艺流程长且复杂,中矿循环量过大,水资源消耗高,选矿成本居高不下。与当下的提质增效,节能降耗的绿色矿山理念相悖。为了解决常规磁选设备的磁性和非磁性夹杂,采用经济有效的选矿手段获得高品位磁铁矿精矿或超纯磁铁矿精矿,为此,各研制单位做了大量的工作,如增加筒式磁选机的极数,提高精矿粉的翻滚次数,适当降低精矿端的磁场强度,在卸矿端弱磁区加冲洗水、加装震动装置、脉动磁场及旋转磁场磁选机等,但上述种种办法,均对提高精矿品位收效甚微,因此,开发一种提质增效,节能环保的磁选设备成为当前的首要任务。电磁淘洗机应运而生,电磁淘洗机是一种高效的磁铁矿精选设备,为磁铁矿选矿厂提精降杂工程和选矿技术进步做出了贡献,创造了较大的经济效益。但是,传统电磁淘洗机仍存在以下问题:为了防止跑矿,在电磁淘洗机的洗选筒外周顶部设置有用于拢矿的磁场线圈,因沿洗选筒的筒壁至筒内中心位置的磁场逐步递减,使得洗选筒内部分区域成为无磁区和弱磁区,对于该区域,在水流偏大时是无法利用磁场吸附住随水流上升的微细粒精矿的,因此,该拢矿磁场线圈在稳定的分选环境下作用微乎其微,在水流或矿浆量波动偏大时,又起不到决定性的控矿作用,极易造成 ...
