摘　　要：螺杆类挤出机的广泛应用促进了挤出机的发展创新。三螺杆挤出机是挤出机械领域的又一新创意,以其灵活多变的几何排布方式、多个啮合区,形成物料在流向、流速上的多重变化,且质点在空间位置的分布产生了极其有益的影响,以优异的混合特性、小的长径比、较高的产能比受到关注。The wideranging applications have promoted the development and innovation of screwlike extruders. The triple screw extruder is the one newly created intention in the field of extruding machinery which has begun to be paid close attention by a lot of advantages such as flexible and changeable form of arrangement in axes of screws,multiple meshing region,multiredisplacement of the position of melt flow,small ratio of length to diameter,higher ratio of yield to energy dissipation and the excellent properties of mixing.
