双螺杆捏合机理及其捏合段设计

定性分析了捏合段的混合及输送机理，讨论了捏合块错列角、螺棱间隙、捏合块头数、螺杆转速等因素对混合质量及输送能力的影响，并由此提出了一些捏合段设计时应注意的问题。

STUDY ON THE KNEADING MECHANISM AND DESIGN OF THE KNEADING ZONE OF TWIN SCREW EXTRUDER

he mixing and conveying mechanism of the kneading zone was analysed. The effects of the stagger angle and tip number of the kneading blocks, the gap between the screw and the barrel, as well as the screw speed on the mixing ability and conveying capacity of the kneading zone were discussed. Based on these, some problems, which should be taken into account when designing a kneading zone, were pointed out.
