    摘要： An improved extruder apparatus is disclosed and which includes a cylindrical barrel having a feed end and a discharge end, the feed end having an inlet in fluid communication with a hopper. The extruder screw is mounted in the cylindrical barrel, and the screw has an outer surface having one or more helical flights mounted thereon. wherein the inlet end of the cylindrical barrel has a support frame mounted thereto, wherein an upper surface of the support frame is connected to a throat of a hopper, wherein an insert is mounted to the support frame and has a lower end which extends down into the cylindrical barrel, wherein the insert has an internal passageway having a first opening on the lower end and a second opening upstream of the screw for relieving the pressure.

    摘要： A planetary extruder for producing and processing polymers includes a degassing section. The extruder includes a housing and a bushing arranged therein. The bushing has an internal toothing with a pitch diameter and a root circle. An externally toothed central spindle is arranged within the housing. Planetary spindles rotate about the central spindle between the central spindle and the bushing. A heat transfer fluid is guided through fluid channels which extend helically along an outer surface of the bushing and guide the heat transfer fluid axially. A degassing opening is provided to which a negative pressure is applied for degassing. A minimum radial thickness (t) of the bushing between the root circle of the internal toothing on an inside of the bushing and a bottom of the fluid channels on an outside of the bushing is selected based on the pitch diameter (d) of the internal toothing.

    摘要： A dispersive mixing element for co-rotating twin screw extruder is disclosed. The element for co-rotating twin screw extruder comprises of a continuous flight helically formed thereon having a lead ‘L’, wherein either the flight transforms at least once from an integer lobe flight into a non-integer lobe flight in a fraction of the lead ‘L’ and transforms back to an integer lobe flight in a fraction of the lead ‘L’ or the flight transforms at least once from a non-integer lobe flight into an integer lobe flight in a fraction of the lead ‘L’ and transforms back to a non-integer lobe flight in a fraction of the lead ‘L’.

    摘要： A screw for a plasticating apparatus has one or more helical flights. A portion of the screw has a plurality of advancing grooves arranged in a noncontinuous helix cut in the screw. The advancing grooves are dimensioned to receive material therein as the material is conveyed through the barrel. The screw has a plurality of noncontinuous cross-cut grooves traversing one or more of the advancing grooves. The cross-cut grooves have a second helix angle greater than the first helix angle and less than ninety degrees; and/or one or more of the cross-cut grooves have a third helix angle of about ninety degrees.
