Abstract

La présente invention concerne un mélangeur de caoutchouc en continu qui comporte un moteur couple (1), une chambre de mélange (2), des rotors (3), des arbres à vis sans fin (4), un orifice de purge d'air (5), un orifice d'admission (6), des conduits d'eau de refroidissement (7), une tuyère d'éjection (8), un accouplement d'arbres (9a), des chemises d'arbre (9b) et un moteur électrique (10). En raison de la forme particulière de la surface de la paroi intérieure de la chambre de mélange (2) et de la surface des rotors (3), on obtient non seulement une force de cisaillement élevée, comme dans les laminoirs et les mélangeurs internes classiques, mais on augmente également le rendement du traitement, on stabilise la qualité des produits et on améliore l'environnement de travail.
