Abstract

L'invention concerne un appareil mélangeur fonctionnant en continu. Un appareil selon l'invention comporte un rotor et un stator, le rotor ayant une section 4 dans laquelle le filet unique 7 de la partie d'entrée et de compression 2 et 3 est remplacé par un nombre important de filets 18 complémentaires des filets de la section correspondante du stator, les angles d'hélice pour le rotor et le stator étant complémentaires et compris respectivement entre 0 degrés et 45 degrés et enfin 45 degrés et 90 degrés pour assurer une subdivision suffisante pour le mélange et le malaxage de la matière. Un appareil selon l'invention convient en particulier pour un mélangeur-extrudeur pour le caoutchouc.
