| Abstract: | Based on the classification process theoretic analysis of a turbo air classifier, the effective interior of a turbo air classifier can be categorized into five subspaces: the main dispersing region, dispersing separate region, second separate region, auxiliary separate region and the resistance region. The function of each region performed was discussed in the classification process. The categorization was confirmed by material classification experiments. The structures of the main dispersing region, dispersing separate region, and the second separate region were improved to obtain better classifying index. Based on the observations described, it gives a guide to understand and improve the function of a turbo air classifier as well as to develop a new turbo classifier of high efficiency. |
