Abstract

L'invention concerne un malaxeur conçu pour malaxer mécaniquement une matière avec beaucoup d'efficacité en faisant passer la matière, grâce à son propre poids, dans une décroissance libre du malaxeur par des passages modifiés dont la forme transversale varie graduellement dans le sens de la longueur. On assemble plusieurs éléments (11a, 11b), présentant plusieurs passages (12, 13) modifiés sensiblement verticaux, dotés d'un orifice d'admission (12a, 13a) et d'un orifice de sortie (12b, 13b) respectivement à une extrémité et à l'autre extrémité de chaque élément, et dont la forme transversale varie en continu de l'orifice d'admission à l'orifice de sortie; et on les positionne de sorte que les passages modifiés s'étendent sensiblement à la verticale. L'orientation des passages (12, 13) modifiés change d'un élément à l'autre de sorte que des passages directs d'un orifice d'admission à un orifice de sortie n'existent pas dans les éléments.
