Biaxial continuous kneading extrusion device

Abstract

A biaxial continuous kneading extrusion device (10) includes a biaxial kneading feeder (16) including two passage sections (11, 12) arranged in parallel in a state of communication with each other, and first and second kneading feed shafts (14, 15) rotatably arranged in the two passage sections, respectively, to knead a supplied material and a uniaxial screw section including a single passage section that receives the material fed out from the biaxial kneading feeder, and a separate screw shaft rotatably disposed in the single passage section to extrude the material. In each of the first and second kneading feed shafts, a mixing rotor is formed in at least one section in an axial direction, a maximum outer diameter section is formed in a section of an outer periphery of the mixing rotor, and a chip clearance is formed between the maximum outer diameter section and inner walls of the passage sections.
