摘要： The invention relates to an extruder comprising a housing having at least two axially parallel shafts that can be driven in the same direction, wherein the extruder is provided with at least double-threaded conveying elements (2, 11, 12, 21, 22, 31, 32, 41, 42, 43, 50, 51, 52, 53), which mesh with each other and which wipe each other off at an axial distance (Ax) with low backlash at the entire circumference, wherein there is a distance (a) between the comb (6, 6') of the at least one further thread and the inner wall (1) of the housing. Each conveying element (2, 11, 12, 21, 22, 31, 32, 41, 42, 43, 50, 51, 52, 53) has at least two angularly twisted conveying sections (3, 4; 11a to 11f, 12a to 12f; 21a to 21e, 22a to 22e; 31a to 31e, 32a to 32e; 41a to 41e; 50a to 50e; 51a to 51e; 52a to 52e; 53a to 53e), wherein each conveying section has an axial length (Ls) that corresponds at most to the outer diameter (Da) of the conveying element (2, 11, 12, 21, 22, 31, 32, 41, 42, 43, 50, 51, 52, 53).

摘要： The invention relates to a multi-shaft extruder for the continuous treatment and/or processing of bulk material, especially a powdery, granular or flocculent product, comprising a plurality of shafts (3) which are arranged in a crown-like manner in a cavity (1) of an extruder housing (2), said shafts extending parallel to the axial direction (A) of the extruder and forming an inner processing chamber (1a) inside the crown, and an outer processing chamber (1b) outside the crown. Each shaft carries a number of axially successive processing elements (4), at least part of the same being elements (4a; 4c; 4e) having a transporting effect, and with which adjacent shafts engage in a sealed manner at least in partial regions. At least one transporting endless screw element (4b; 4d; 4f) comprising at least one transporting screw thread (9, 10; 14, 15, 16; 19, 20) is placed in the region of the supply opening (21) in the extruder housing (2), and does not engage in a sealing manner in at least one partial region along the axial direction (A).

摘要： The invention relates to a screw element with an external radius Ra and a core radius Ri, for multi-screw extruders with mutually-sweeping screw shafts rotating in the same sense, in particular for double screw extruders, which have a profile in the axial cross-section through the longitudinal axis thereof, which has just one screw land (1, 1'), corresponding to a conventional simple screw for mutually-sweeping screw shafts, on each of both axial faces (front face 8, rear face 8'). The width (sweep angle j) of the screw land (1) and conversely the width (sweep angle j) of the screw land (1') are embodied in a particular manner and a shear land (7) with constant shear land radius Rs, which is greater than Ri and smaller than Ra is provided.

摘要： A plasticating screw for a machine for processing thermoplastic resins in the field of extrusion and molding, characterized in that the profile of the threads is adapted to balance and center the screw in the cylinder and to separate the particles that have started to melt due to the heated cylinder and to impart two speeds, a very high one to the melted material, and to slow the cores of the granules that are still solid. The threads, with the aid of the change of bottom and angle, alternately reduce and increase the diameter, imparting to the solid granules a considerable compression which, combined with the rotation, upon contact generates friction, which facilitates melting and also optimum mixing due to the different speeds.

摘要： An axially elongated extruder screw (22) includes a screw body having an axially extending extruding portion defined by a feed section (F) at an inlet end of the screw, a metering section (M) at an outlet end of the screw and a barrier section (B) between thea feed and metering (M) sections. A first helical primary flight (42) extends about and is coaxial with the screw body along the length of the extruder screw (22). A second helical primary flight (48) extends at least part-way along the feed section to the outlet end of the extruder screw (22). The barrier section (B) of the extruder screw defines first and second barrier flights positioned between the primary flights (42, 48) and cooperating therewith to form first and second melt (70, 76) and solids (56, 58) channels that extend along the barriers section (B) of the extruder screw (22).
