The Impact of Different Screw Edge Width on Extrusion Quality of the Single-Screw Extruder

Abstract:

The screw edge width is usually selected based on experience when designing screw extruders, and it is difficult to get the best extrusion quality. The extrusion process of screw extruder is a process of multi-phase flow, which includes gas, liquid and solid. Making it simplified to single-phase flow process can cause relatively large error. This paper adopts the method of multi-phase flow to simulate the extrusion process of single-screw extruder based on different screw edge width by using the finite element analysis software, and get the conclusion that increasing the screw edge width appropriately under the condition that the production efficiency is acceptable is helpful to improve the extrusion quality of single-screw extruders.
