Through analyzing the performance parameters of superfine powder wormgear classifier,the velocity distribution of gas stream flowing in the classifier was built up, and the particle diameter formula for wormgear classification was derived.Based on the relations of wormgear structure dimensions,rotating velocity and gas flowrate with the classifying diameter and precision of the particles,an improved collecting system was designed.The experimental results show that the collecting efficiency of the classifier is greatly increased with the improved collecting system.
