在从几种重矿物的精矿中分选钛铁矿时,用稀土永磁高强度磁选机进行了分选试验,并且与传统工艺包括电磁感应磁辊(IMR)磁选机及交叉带式磁选机进行了比较。稀土筒式磁选机和辊式磁选机的分选性能与电磁磁选帆的性能不相上下。与电磁磁选机相比,这种稀土磁选机结构简单、处理量大、生产成本低,设备体积小,在习惯选用电磁感应磁辊磁选机和交叉带式磁选机的地方,应该认真考虑选用这种稀土磁选机。为了利用这种处理能力大、生产成本低的稀土型磁选机回收大部分的钛铁矿,建议在选别钛铁矿和白钛石时,把稀土筒式磁选机和辊式磁选机结合起来使用。为了回收磁性弱的白钛石,要为稀土辊式磁选机确定最佳的给矿量。
In the separation of ilmenite from several heavy mineral concentrates, the rare earth permanent magnetic high-intensity magnetic separator was used for sorting tests. Compared with the traditional process including magnetic induction magnetic roller (IMR) magnetic separator and cross belt Magnetic separator was compared. The sorting performance of rare earth drum magnetic separator and roller magnetic separator is comparable with that of electromagnetic magnetic picker. Compared with electromagnetic magnetic separator, the rare earth magnetic separator has the advantages of simple structure, large processing capacity, low production cost and small equipment volume. Where the conventional induction magnetic roller magnetic separator and cross belt magnetic separator are used, Seriously consider the use of rare earth magnetic separator. In order to take advantage of this ability to handle large, low cost production of rare earth magnetic separator to recover most of the ilmenite, it is recommended in the selection of ilmenite and white titanium stone, the rare earth magnetic separator and roller magnetic separator Machine used in combination. In order to recover the weak magnetic white titanium stone, rare earth roller magnetic separator to determine the best amount of ore.
