| Abstract: |
| In this article，the development of the screw configurations of cold feed rubber extruders
was reviewed. Firstly，the geometry features and mixing and plasticizing capability of the basic screw
configuration of the cold feed extruder were summarized. Then，the structural characteristics，mixing and
plasticizing principle of the plasticizing section with different screw configurations，including the main
and secondary screw flight configurations, interrupted and grooved screw flight configurations，pin barrel
configurations，transfer mixing configurations，and lug screw configurations，were discussed. Moreover，the
structure and characteristics of the feeding section of the cold feed extruder were also reviewed. In the last
part，the development trend of the screw configurations of the cold feed extruder in the future was predicted. |
