    摘要： An mixing section for an extrusion screw has an inlet end and an outlet end as well as alternating wiping lands and barrier lands. The wiping lands have a greater helix angle than the barrier lands. The wiping lands and the barrier lands define inlet channels which narrow toward the outlet end and outlet channels which widen toward the outlet end. A helical pattern of mixing channels is cut into the wiping lands and the barrier lands. The mixing channels may be oriented generally at approximately right angles to the wiping lands and the barrier lands. A portion of the extrudate encounters the inside wall surfaces of the mixing channels and changes direction which improves the mixing of the extrudate.

    摘要翻译： 用于挤出螺杆的混合部分具有入口端和出口端以及交替的擦拭区域和障碍区域。 擦拭地面的螺旋角大于挡土墙。 擦拭区域和阻挡区域限定了朝向出口端变窄的入口通道，并且朝向出口端变宽的出口通道。 将混合通道的螺旋图案切割成擦拭区域和阻挡层。 混合通道可以通常以大致垂直于擦拭平台和阻挡层的角度定向。 挤出物的一部分遇到混合通道的内壁表面并改变方向，这改善了挤出物的混合。

    摘要： An extruder screw that enables mixing of viscous materials, such as rubber mixtures and thermoplastic materials, is disclosed. The screw includes a core extending from a sealing end to a nose cone end. At least one flight extends radially from the core in a quasi-helical pattern, wherein flights adjacent one another form channels therebetween. A plurality of elongate lugs extend radially from the core and are disposed in the channels. The shape as well as the number of lugs can be varied to ensure the requirements for a thorough and turbulent deflection and mixing of the material stream.

    摘要： What is described is a twin screw extruder having two extruder screws (10, 34), each extruder screw (10) having a cylindrical core (12) and at least one web (14) running helically over the periphery of the outer cylinder face of the core (12), the surface of the web (14) comprising a peripheral side (18) and two flanks (22, 24), and a channel (30) being formed between adjacent web windings. The flanks (22, 24) of the web (14) have a waved progression in the peripheral direction.
