摘　　要：为研究不同导风叶片偏转角度的立式磨速度场、压力场以及颗粒分级筛选性能的变化规律,建立HRM22.2X立磨全流域流场模型,利用Fluent软件中MRF模型和DPM模型模拟选粉机转子旋转及磨内气固两相流运动。研究结果表明,选粉机导风叶片偏转角度为40°时立式磨整体性能最优。To investigate the influence of different deflection angles of wind guide blades on the velocity field,pressure field,and particle classification performance of vertical mills,a full-domain flow field model for the HRM22.2X vertical mill was established.Using the MRF and DPM models in Fluent software,the rotor rotation of the powder separator and the gas-solid two-phase flow within the mill were simulated.The results indicate that the vertical mill achieves its optimal overall performance when the deflection angle of the powder separator’s wind guide blades is set to 40°.
