在铁精矿脱水作业中,我们用φ600×1750毫米半逆流式永磁磁选机代替了原来的两段磁力脱水槽(图1),提高了过滤机的给矿浓度,降低了溢流的含铁量,减少了金属流失。但是,由于这台永磁机的磁块是用过的旧磁块,有小部分磁块极性排列不规则,磁场强度低,使得生产效果不十分理想。我们学习兄弟单位的经验,在永磁磁选机槽体内加一块磁感应铁板,明显地提高了磁场强度,进一步改善了脱水选别效果。
In the iron concentrate dehydration operation, we use φ600 × 1750 mm semi-countercurrent permanent magnetic separator instead of the original two magnetic dewatering tank (Figure 1), to improve the feed concentration of the filter to reduce the overflow Iron content, reducing the metal loss. However, since the magnet of this permanent magnet machine is a used magnet, a small part of the magnet has an irregular arrangement of polarities and low magnetic field strength, so that the production effect is not very satisfactory. We learn the experience of brothers units, plus a permanent magnet magnetic separator tank induction magnetic plate, significantly increased magnetic field strength, to further improve the dehydration sorting results.
