Open publisher page 0 citations

Abstract

Numerical simulation was used to study the helical grooved structure in inner wall of traditional extruder barrel which formed the single extruder with helical grooved barrel.POLYFLOW software was used to calculate the 3D isothermal flow fields and mixing process of PVC-R in the single screw extruder with helical grooved barrel.The influence of groove depth in the single screw extruder with helically grooved barrel was mainly studied.Results showed that,when the gaps between screw and barrel were kept the same,it benefited mixing with bigger groove depth of the helically grooved barrel.
