我矿采用CS-1型感应辊式强磁选机对4～0mm原矿进行精选。该机原给矿器填料箱为干式油棉盘根填料密封,往往使用不到一个月,即出现严重漏矿现象。针对此情况,我们对给矿器填料箱进行了改进。改进后的填料箱增设水封室及筒形橡胶端面密封(附图)。高位水池压力水(>1.5kg/cm~2)经给水管进入水封室,并与端面密封胶圈组合 I mine using CS-1-type induction roller strong magnetic separator on the 4 ~ 0mm ore selection. The original machine to the filler box for dry packing cotton packing, often used less than a month, that is, serious leakage phenomenon. In response to this situation, we have to improve the feeder box. Improved packing box additional water chamber and cylindrical rubber seal (with photos). High pool pressure water (> 1.5kg / cm ~ 2) into the water seal by the water supply chamber, and the combination of the face seal
