摘　　要：本文采用理论与实验相结合的方法，探讨了组合式旋转分离器的设计方法。确定了分离器中各主要的结构尺寸。从理论上导出了转子旋转功耗及气粉流产生的阻力矩计算公式，并进行了实例计算。本文的设计方法对于改善我国配ＭＰＳ磨煤机的组合式旋转分离器的设计具有重要的实际和理论价值。On the basis of the theoretical analysis and experimental research work, the primary structural sizes of the Guide-Vane Bladed-Rotor Classifier are recommended in this paper. Calculation model for predicting power requirements of rotating bladed-rotor and moment of drage force produced by the gas-particles flow are presented. The practical example calculation using the obtained formulas are also described. The design methods discussed here are important for improving the existing design theory and methods of the Guide-Vane Bladed-Rotor Classifier for MPS type medium speed coal mills in China.
