当今,开采利用难选铁矿石已势在必行,但这种矿石选别时,铁的损失相当大。现有的弱磁选设备不能保证铁矿物得到有效回收,而且也不能使铁矿物与贫连生体和脉石有效分离。筒式磁选机的结构不断完善的情况表明,磁场力增大,尾矿铁损失减少,磁选机 Today, the exploitation of refractory iron ore has been imperative, but this ore sorting, the loss of iron is quite large. The existing weak magnetic separation equipment can not guarantee the effective recovery of iron ore, but also can not effectively separate the iron ore from the lean creature and gangue. The continuous improvement of the structure of the drum magnetic separator shows that the increase of the magnetic field force reduces the loss of tailing iron and the magnetic separator
