Abstract： To seek out the best match of air flow and rotor speed of a classifier and improve the classification effect of the classifier, an evaluation method of classification effect about the classifier was proposed with SLK5500 classifier classifying cement raw meals as the basis. By designing orthogonal experiments, the primary and secondary relationship of air flow and rotor speed on the yield and 80 μm residual value was studied. The results show that the best match scheme of the classifier is obtained as the air flow of 6 000 m3/min and the rotor speed of 55 r/min. The scheme is successfully applied in production debugging. The classification effect of SLK5500 classifier is improved. The yield is increased from 52.6% to 66.4% at the condition of 80 μm residual mass fraction less than 15%.
