The endured forces of the solid particle which distributed in the air were analyzed. Based on that, the structural characteristics and classifying principles of the centrifugal rotor classifier were introduced. The classifying mechanism was analyzed and calculation formula of cut size was deduced. By model tests, the influence of operation parameters on the classifier's performances was studied. The experimental results show that the classifier's performances are superior and the theoretical analysis has more significant on designing the classifier and predicting its performances.
