在磷矿石的浮选过程中,进入浮选机的矿量是经常波动的。特别是当发生粉矿仓堵塞、给矿机断矿、球磨机“胀肚”等现象;或球磨机临时停车紧筒体螺丝时,磨机的出矿量突然减少,而给药量不能及时地跟着改变,就会导致浮选药剂的浪费,并给浮选操作造成困难。为了改善这种情况,我们在磨浮工段装设了一套“给药量前馈调节”装置。它在实现按进入球磨机的矿量大小自动调整浮选药剂用量的同时,还可供浮选工对给药量进行远控调
During the flotation of phosphate rock, the amount of ore entering the flotation vessel fluctuates frequently. Especially when the occurrence of powder ore warehouse blockage, to the mine machine, ball mill “bloating” and other phenomena; or the ball mill temporary parking tight cylinder screw, the mill suddenly reduced the amount of mine, and the dose can not be followed in time Change, it will lead to the waste of flotation reagents, and cause difficulties for flotation operations. In order to improve this situation, we installed a set of “feed-forward adjustment” device in the grinding and floating section. It is in accordance with the size of the mine into the ball mill automatically adjust the amount of flotation reagents, but also for the flotation of the amount of medication for remote control
