Abstract

A centrifugal separator is provided with a rotary distributor provided with a plurality of vertically spaced coaxial rotating disks, in which the upper rotating disk is of smaller diameter than the lower rotating disk. The distance between the disks may be adjustable. The lower disk baffles an updraft separating air current whereby powdered material is separated from the coarser material as centrifuged from the upper disk, and any material escaping the upper disk without being thrown thereby into the air stream drops down on the larger lower disk and is thrown into the air stream by the lower disk. Either or both of the disks may be provided with agitator vanes.
