| 摘 要： | 通过构建不同叶片间距和安装倾角的立磨选粉机模型，采用CFD软件模拟分析了转子叶片间距与安装倾角对分级区速度场的影响及分级效率的变化规律. 对立磨选粉机转子进行了基于叶片间距及安装倾角的改造试验，结果表明，改造后的转子叶片数为48、安装倾角为5o的立磨选粉机产量比叶片数为72、安装倾角为0o的提高了0.5~1 t/h，且减小了循环负荷与能耗，降低了成品生产成本与设备制造成本.

| Abstract: | Models of vertical milling classifier with different rotor blade spacings and tilt angles of installation were built,and their effects on the velocity field and classification efficiency of classifier simulated by CFD.Structural transformation in the spacing and tilt angle of classifier was tested,and the result showed that after transformation,the production of vertical milling classifier with rotor blade number of 48 and installing tilt angle of 5o was increased by 0.5~1 t/h compared with that with the rotor blade number of 72 and installing tilt angle of 0o.And the cyclic loading and energy consumption were reduced and the cost of device and product was lowered. |

| Keywords: | vertical milling classifier rotor blade spacing tilt angle of installation velocity field classification efficiency |
