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 toward the evacuation conduit as two separate and parallel streams.

[ What is claimed is:] [1.]1. A centrifugal type pneumatic separator comprising:a rotor having a vertical axis, said rotor having a plurality of vanes distributed around a periphery thereof;a housing containing said rotor, said housing having an air input means and a material input means, said material input means for passing material into said rotor, said housing having an evacuation conduit means for passing air laden with a fine fraction of material, said housing having an outlet means for passing a coarse fraction of material from said rotor, said air input means for passing air to a periphery of said rotor through channels formed between adjacent vanes of said plurality of vanes such that the air flows within said rotor toward said evacuation conduit means, said rotor being divided to define at least two separate passages whereby air from said air input means flows toward said evacuation conduit means as at least two separate streams in parallel relation, said rotor comprising a channel adjustment means connected to at least some of said plurality of vanes for varying a cross-sectional area of some of said channels; andadjustment means connected to said rotor for adjusting a flow rate of at least one of said separate streams.
