介绍了螺旋磁场磁选机的结构特征、工作原理及特点。用某选矿厂的铁精矿在实验室进行了螺磁机的单元格精选试验,精矿品位比精选前提高2~6个百分点。用φ600螺磁机进行了铁精矿的现场精选工业试验,取得了初步成功。
The structure, working principle and characteristics of spiral magnetic field magnetic separator are introduced. With a concentrator of iron ore in the laboratory conducted a spiral machine cell selection test, concentrate grade than the pre-selection increased by 2 to 6 percentage points. The φ600 auger was used to carry on the on-the-spot industrial test of iron concentrate, and achieved initial success.
