Study on the Separation of Powder by a Cyclone

Abstract

We measured the inner flow of a cyclone, and from the results, computed the size of the separated powder of a given density when the cyclone was driven at a constant rate.
Comparing the experimental results with those computed, we found that there was a close similarity between them. At the same time we found that the limiting size of the powder which is separable was not determined, but a part of the powder whose size belongs to some range, and the powder whose size is larger than that were caught.
Hence, we propose the "Characteristic Curve of separation" in order to represent the separation of powder by a cyclone.
