| Abstract: |
| The relationship between the extrusion pressure，extruder output and screw rotation speed was analyzed，which was used to explain the problems of traditional cold feed rubber extruder during production.The new type extruder with extrusion pressure control and its disadvantages were also introduced.Based on that，a new method of screw speed control by combined control on extrusion pressure and extruder output was proposed. The new control method took into account the geometrical structure parameters of different parts of the screw and correction to compound viscosity，and could improve the quality and output of extruded products. |
