Beschreibung
Zusammenfassung:	A continuous kneading device (1) includes a pair of kneading rotors (3), being capable of increasing mesh between the kneading rotors (3) while suppressing a kneading load applied to the kneading rotors (3). The continuous kneading device (1) includes a barrel (2) and a pair of kneading rotors (3) housed in the barrel (2) and rotating in mesh in directions different from each other. Each kneading rotor (3) includes a plurality of kneading flights (11, 15) for kneading a material supplied into the barrel (2). The kneading flights (11, 15) and respective portions of the barrel (2) housing the kneading flights (11, 15) respectively configure a plurality of kneading sections aligned axially of the kneading rotors (3). The material is fed axially from the upstream kneading section to the downstream kneading section to be sequentially kneaded. The kneading flight (15) constituting the downstream kneading section has a rotational outer diameter (D2) larger than a rotational outer diameter (D1) of the kneading flight (11) constituting the upstream kneading section.
