Abstract

A centrifugal type pneumatic separator having a rotor and a housing. The rotor has a plurality of vanes distributed around a periphery thereof. The housing contains the rotor. The housing has an air input conduit, a material input conduit and an evacuation conduit. The air input conduit passes air through channels formed between adjacent vanes such that air and material flows toward the evacuation conduit. The rotor is divided so as to define at least two separate passages whereby air from the air input conduit flows into the evacuation conduit as two separate and parallel streams.
