    摘要： The invention relates to a multiple-screw extruder that comprises a first process chamber (1) and a second process chamber (2). In the degassing zones of said extruder, at least the first process chamber is provided with at least one degassing opening. The radius R of the conveyor element in the degassing zones, in at least one conveyor element (7; 9) of at least one screw (5, 7; 5, 9) configured as a passage screw, in a subsection configured as a passage subsection (71a, 71e; 91a, 91e), along the peripheral direction of the at least one conveyor element (7; 9) is by ΔR smaller than the full radius Rv of the conveyor element (6; 8) required for the mutual stripping of adhering product in a closely intermeshing screw operation with die adjacent conveyor elements (6; 8) of adjacent conventional screws (5, 6; 5, 8). The invention also relates to a method for degassing viscous or elasticoviscous flowable masses in such a multi-screw extruder having several process chambers, the respective process chambers communicating by means of a connecting opening.

    摘要： An extruder for processing of thermoplastics has a housing (1) in which a screw is pivotally supported. A land (5) which runs in a helical line protrudes from the core (4) of the screw. There is at least one ventilation opening in the housing in which the screw is pivotally supported. The land (5) of the screw at least in the area of the ventilation opening has an active flank, i.e. one which points toward the discharge end of the extruder and which encloses with the axis of the screw an acute angle such that at least in areas it is set back relative to a radial plane which passes through the outside edge (14) of the active flank (10). This prevents the plastic which is to be processed in the extruder from being pressed to the outside and clogging the ventilation opening.

    摘要： A new plasticity apparatus including a rotating and reciprocating screw having a hellcal flight that is wrapped around a core, disposed within and cooperting with the inner wall of a heated barrel that substantially increases the melt quality of a polymeric material. This is accomplished by incorporating an increase in the hefix angle of the primary flight at the taper terminus of the transition section, in cooperation with a stepped change in the root that terminates either upstream or downstream of the end of one complete revolution of the flight.

    摘要： The extruding apparatus has the molding die to form the ceramic molding, the screw extruder containing the extrusion screw to knead and guide the ceramic material toward the molding die. The extrusion screw is comprised of the pressure screw part and the diffusion screw part. The diffusion screw part provided at the front end of the extrusion screw has a diameter greater than the screw diameter of the pressure screw part.

    摘要： An apparatus for mixing thermoplastic materials is provided. The apparatus includes a barrel and a screw rotatably mounted in the barrel. The screw has a screw shaft with a thread spirally extending around the screw shaft so as to form a plurality of flights, and the screw has a zone through which melted polymer conveyed. The screw has a portion that is without a screw thread where the screw shaft forms a mixing element with a drum-shaped surface extending above the screw shaft that is coaxial with the screw shaft. This drum-shaped surface has a plurality of alternating input grooves output grooves extending in a generally axial direction. Lands extend between the input grooves and output grooves so as to separate the input grooves from the output grooves, with the length of each land being substantially equal to the length of the contiguous portion of the adjacent input and output grooves. There is a land cross-sectional shear area corresponding to each land that is equal to the length of the land multiplied by the clearance between the land and the inside surface of the barrel hollow space, and the summation of the land cross-sectional shear areas for all of the lands of the mixing element is greater than or equal to 95% of the flow cross-sectional area between the adjacent flights of the screw through which polymer passes immediately prior to entering the mixing element.
