Abstract

Elément interne de mélangeur comprenant au moins deux canaux qui se croisent. Cet élément 1 est constitué d'une pièce monobloc pleine, usinée dans la masse, les canaux 3 sont parallèles et dans des plans parallèles, l'angle compris entre un canal et l'axe 2 de la pièce projeté dans ce plan est de préférence compris entre 30 et 60 degrés , l'angle d'inclinaison des canaux sur l'axe des mélangeurs étant une fois positif et une fois négatif dans les plans qui se succèdent et donc les canaux des plans voisins se croisent en formant ainsi une grille et la section des canaux est suffisamment grande pour que le recouvrement des canaux voisins soit d'environ 10 à 30 % aux points de croisement. Application par exemple à l'uniformisation de la matière en fusion à la sortie d'une extrudeuse, par exemple en amont d'une filière.
