摘　　要：用模化试验的方法找出了评价组合式分离器特性的各种关系曲线．试验结果表明，组合式旋转分离器分离效果好，能满足磨制超细煤粉的要求．同时考察了组合式旋转分离器的阻力特性．分离器本体部分阻力损失为８００～１４００Ｐａ，比桨叶式分离器的要大，但由于组合式旋转分离器的中心回粉方式能降低磨煤机总压损，因此，磨煤机与分离器的总阻力较小，可用率能满足电厂的高要求．Abstract In this paper, cool mode tests for the rotary type classifier combined with static naps and rotating blades for MPS typemill are completed. Some Performance curves are established.The results show that it is of best classifying performance,and can meet harsh pulverized coal fineness requirements.Meanwhile, its resistance characteristics is also investigated inthis paper. The total loss of rotary type classifier less than theour blades classifier, and can meet the requirement of the utility plant.
