ABSTRACT:
The present invention is directed to apparatus and a process for separating large from small particles suspended in a moving stream of gas by centrifugal forces which in a preferred embodiment includes sifting of large particles in a stream of gas to strip small particles away from the larger particles. The apparatus and process is especially adapted for separating dry finely divided particulate materials having small particles from about 0.05 micron to about 45 microns from larger particles suspended in the moving gas stream.
