| Abstract: |
| On the basis of a 3D flow numerical simulation by Fluent for melt and gauge stage compound of cold-feed pin barrel extruder，the effects of screw’s rotating speed，upward pressure，pin’s count，array pitch of pins and flight channel depth on flow mass and torsion were investigated.The results showed that main influential factor on power consumption was rotating speed of screw.When the speed increased，flow mass increased，power and power consumption(ratio of torsion and flow mass) decreased.As upward pressure increased， power consumption increased.Array pitch of pins had more significant effect.If considering only flow mass and power consumption，greater array pitch of pins was preferred. |
