摘　　要：磁介质棒是立环高梯度磁选机重要的组成部分,对平滑和搓齿两种圆钢棒激磁后的磁场分布和梯度从理论进行了分析,并选用来自刚果(金)的铜钴矿进行了对比试验。试验结果表明,在铜钴矿的磁选中,搓齿圆钢棒比平滑圆钢棒具有更好的富集效果。Magnetic medium bar is important component of vertical ring high-gradient magnetic separator.The paper analyzes theoretically about the magnetic field distribution and gradient after initiation of smooth and gear rolling steel rod bars.It also selects copper-cobalt ore from Democratic Republic of the Congo for comparison test.The test result shows that in the magnetic separation of copper-cobalt ore,the gear rolling steel rod bar has better enrichment effect than smooth steel rod bar.
