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： 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 the 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： The invention relates to an extruder for continuously processing and/or treating free-flowing substances, comprising at least two parallel shafts that rotate in the same direction. Said shafts are fitted with intermeshing screw elements, whose face is delimited by arcs of a circle, which correspond to the outside diameter of the screw, to the core diameter of the screw and, at most, to the axial distance of the screw elements, and which are guided on circular segments of the extruder housing that are parallel to the shafts. At least one screw element (1) comprises a number of interspaced concentric annular sections (8) that are formed by recesses (12) in the screw element (1).

摘要： The invention relates to a screw pump comprising an inlet cross-section and an outlet cross-section for conveying free-flowing media, in particular plastic melts and rubber blends. Said pump comprises two screw shafts (20, 21), having a distance (α) between their axes, which are located in a pump housing (3) comprising two partially overlapping housing bores (4, 5) that run through said housing (3) in a longitudinal direction and which can be rotationally driven in an equidirectional manner. A plurality of single-flight screw element groups (1, 2), which closely intermesh, are arranged on said shafts in a rotationally-fixed manner. The invention also relates to a multi-screw extruder comprising a screw pump of this type.

摘要翻译： 峰角b为0度≤b≤45度。 优选特征：每个捏合盘（25,26）围绕穿过相应的旋转轴线（20,21）并通过波峰中心（31）的中心纵向平面（37,38）是镜像对称的。 两个盘，一个在同一横截面上的每个轴上，形成一对。 它们对着偏移角度z，避免在相同方向旋转时相互干扰。 给出的几何方程定义了这个角度。 角度抵消的原理进一步详细。 圆盘在SRA的套管孔（16,17）中具有径向间隙。 为了形成具有恒定套管孔径的间隙，减小半径RA并且RI增加，使得RA / RI的比率更小。
