  • Dual screw extrusion apparatus having a mixing chamber and a conveying chamber downstream thereof with the mixing chamber having a wall clearance greater than that of the conveying chamber
    Patent number: 9090013
    Abstract: An extrusion apparatus including a mixing chamber comprising two intersecting housing bores and an inlet positioned to receive material into the mixing chamber. Two screw shafts are supported for rotation about respective generally parallel axes and include respective screw sections positioned for co-wiping intermeshing rotation within the respective housing bores of the mixing chamber. The apparatus supports screw shaft rotational speeds greater than approximately 800 rpm and includes screw shaft conveying portions that are rotatably cantilevered for self-journaled support within respective separate conveying chambers arranged generally parallel to one another downstream of the mixing chamber.
