The theory and technical features of dynamic classifier are introduced in this paper, and a new type of dynamic classifier is researched;moreover,experimental investigation is conducted for the purpose of industry application. The development and results of experimental investigation of operating features of dynamic classifier are introduced in the paper. The fineness regulating features and pulverized coal fineness distribute exponent of classifier effected by rotating ratio and air flows are investigated. The separating efficiency of classifier and its effects on maximum capacity of coal pulverizer are also analyzed.
