通过小型实验室试验和半工业试验 ,研究磁力水力分选机对磁性铁燧岩选别的影响。试验参数包括给料流量、给料矿浆固体百分含量和磁场磁感应强度。小型实验室试验结果表明 ,在水力分选机中加入一个磁感应强度为 0 0 0 3T的磁场 ,能有效地防止磁性铁损失。在半工业试验中 ,水力分选机装入磁栅格 ,可以得到一个比较均匀的磁场。半工业试验的研究参数包括给料的磁化 /脱磁和磁化电流的影响。水力分选机即使在很高的上升水流速度下操作 ,磁性铁的损失也显著降低。试验结果还表明 ,增加磁感应强度可以减少磁性铁的损失 ,并且当给料磁化后 ,磁性铁的损失更少
Through the small laboratory test and the semi-industrial test, the influence of the magnetic hydraulic classifier on the magnetic taconite classification was studied. The test parameters include feed flow rate, percent solids in feed slurry, and magnetic induction. The results of small-scale laboratory tests show that adding a magnetic field with a magnetic induction of 0 0 0 3 T to the hydraulic separator can effectively prevent the loss of magnetic iron. In the semi-industrial test, the hydraulic separator is installed in the magnetic grid, you can get a more uniform magnetic field. Research parameters for semi-industrial tests include the effects of magnetization / demagnetization and magnetizing current on the feedstock. Hydraulic separators lose significantly less of the magnetic iron, even at very high ascending water flow rates. The experimental results also show that increasing the magnetic flux density can reduce the loss of magnetic iron, and when the feedstock is magnetized, the loss of magnetic iron is less
