ABSTRACT:
A multi-stage rotary processor particularly useful for processing plastic and polymeric materials. The multi-stage rotary processor includes a rotatable element carrying a plurality of processing channels and a stationary element providing a coaxial closure surface cooperatively arranged with the channels to provide a plurality of enclosed processing passages. Also associated with the stationary element are inlets, outlets and blocking members for each passage and arranged so that material fed to the passage can be dragged forward by the channel walls, and collected at the blocking member for discharge from a passage(s) of one stage to a passage of another. The geometry of the passage receiving material is selected to provide optimum processing efficiency, resulting in a processing rate capability for that passage greater than the rate at which material is supplied to the passage. Adjustable material transfer rate control means are arranged near the inlet of the material receiving passage so that the processing rate of the passage can be adjusted for coordination with the rate at which material is supplied to the passage.
