| 摘 要： | 以COMSOL仿真优化了开放磁系磁场力HgradH模型，设计了基于开放磁系小极面排斥磁极布置的强磁磁路结构，使筒表分选区磁场强度可达到800 mT以上，试验结果表明，与常规开放磁系永磁筒式磁选机相比，新型开放磁系永磁筒式强磁选机分选某细粒铬铁矿、钛铁矿，回收率分别提高了34.11%、16.99%，说明该新型磁选机更有利于细粒弱磁性矿物的回收。

| Abstract: | The model of HgradH represented magnetic force in open magnetic system is optimized with COMSOL. Based on open magnetic circuit, a high field strength magnetic circuit is created with small magnetic pole width and repelling magnetic pole arrangement. Magnetic field intensity of drum surface can reach at 800 mT. The experiment showed that this new permanent magnetic separator with high magnetic field strength can achieve a higher recovery of 34.11% and 16.99% when separating some chromite and ilmenite, than conventional open magnetic system permanent magnet drums type magnetic separator. It turns out that the original type magnetic separator is more suitable for separating fine grain chromite and ilmenite. |
