Abstract: A separation housing houses a rotor with multiple suspension chambers. Each chamber has a radially extending web portion between two rotating discs. An orifice is provided through the radially extending web portion. Another web portion urges gas radially out of the rotor. Passages through the rotating disks permit entry of gas and solid particle mixtures into the suspension chambers at high speed traveling toward each other in a suspension adjacent to the orifice.

The result is gas in the suspension zone being fixed relative to the rotor or changing direction. Centrifugal force moves solid particles radially out of the chamber.
