A 3D finite element simulation model of a ZH high-intensity magnetic separator (HIMS) was established based on Ansys Maxwell. The magnetic field distribution characteristics and the variation law of magnetic field intensity in the separation channel of the separator with three kinds of medium (serrated plate, elliptical rod and cylindrical rod) were systematically analyzed. A simulation experiment on separating particles was conducted by using the discrete element method. The results show that the serrated plate medium produces an obviously focused magnetic field effect at the serrated part, with the maximum field intensity reaching 2.08 T. The periodic strong gradient fluctuation is beneficial to the efficient capture of fine ilmenite particles. The elliptical rod medium can bring good uniformity in magnetic field strength, which is suitable for stable separation of coarse minerals. The cylindrical rod medium leads to a wide magnetic field distribution and can be applicable to separation of mixed materials with wide size fraction. The simulation results are in good agreement with the experimental measurement, which verifies the reliability of the model. Further particle simulation reveals that serrated plate medium can break particle agglomeration and suppress non-magnetic mineral entrainment by periodic gradient reversal, and finally realize the efficient enrichment of ilmenite. It is concluded that the serrated plate medium has significant advantages in separation of fine ilmenite and is the preferred medium for the ZH HIMS.

基于Ansys Maxwell建立了ZH型组合式强磁选机的三维有限元仿真模型，系统分析齿板、椭圆与圆棒3种介质的磁场分布特征以及分选通道中磁场强度变化规律，并结合离散元方法开展了颗粒分选模拟试验。结果表明：齿板介质在齿尖区域形成显著磁场聚焦效应，最大场强达2.08 T，周期性强梯度波动有利于高效捕获微细粒钛铁矿；椭圆介质磁场均匀性较好，适合粗粒矿物的稳定分选；圆棒介质磁场分布宽泛，适用于宽粒级混合物料的分选。仿真结果与试验实测值高度吻合，验证了模型的可靠性。颗粒模拟进一步揭示，齿板介质能够通过周期性梯度反转破坏颗粒团聚，抑制非磁性矿物夹带，最终实现钛铁矿的高效富集；齿板介质在微细粒钛铁矿分选中具有显著优势，是ZH型组合式强磁选机的优选介质。
