摘　　要：介绍了一种新型分级机和由其组成的闭路磨粉系统,指出该系统中影响分级效果的重要因素,并着重对分级机转速和分级叶片处的通流面积两个因素进行了实验研究。结果表明:粉磨方解石时,分级机转速为600 r/min左右、通流面积为0.766 m2时,分级效果较好。A new kind of classifier and the closed circuit milling system consisted of it were introduced. The main factors that influenced the classification effect in the system were pointed out. Experiments were emphatically done to research the two factors, classifier＇ s rotating speed and the flow area via vanes.
