摘　　要：湿法研磨设备的研磨效率与转子几何结构密切相关,不同转子结构和尺寸的湿法研磨设备的效率相差较大。为了解决针对特种物料研磨时多类型转子优选问题,利用DEM-CFD耦合模拟的方法,在保持珠径不变的情况下,针对棒销式转子,盘式转子,涡轮式转子在各转速,各填充率和各粘度的碰撞能量进行对比分析,最终确定棒销式转子具有较好的研磨性能。The grinding efficiency of wet grinding equipment is closely related to the rotor geometry.The efficiency of wet grinding equipment with different rotor structures and sizes varies greatly.In order to solve the optimization problem of multi-type rotors during grinding of special materials,the DEM-CFD coupling simulation method was used to compare and analyze the impact energy of rotor-pin rotors,disk rotors and turbine rotors at various speeds,filling rates and viscosives while keeping the bead diameter unchanged.Finally,it was determined that rotor-pin rotors had better grinding performance.
