The Effect of Screw Speed on Extrusion Quality of the Single-Screw Extruder

This paper adopts the method of multi-phase flow to simulate the extrusion process of single-screw extruder based on different screw speed by using the finite element analysis software, and get the conclusion that the screw speed has a significant effect on the extrusion quality and outlet pressure of the single-screw extruder. With the increase of the screw speed, the extrusion quality of the single-screw extruder gets worse and the outlet pressure of the single-screw extruder increases.
