In this paper,for a ballast cleaning machine,the polygon effect of drived chain is developed to expound the settling mechanism of the straight section of centrifugal sieves,and the formulas of the actual relative sliding velocity and the theoretical relative sliding velocity and the theoretical relative sliding velocity and their mating relation are obtained,Moreover,a theoretical formula of settling probability density is extracted,and with the help of integrating by computer, the settling probability is obtained.Finally,the main factors which effect the settling probability are analysed.By means of the method expounded in this paper,centrifugal cleaning machines with high settling quality and efficiency can be designed.
