Abstract

L'invention concerne la technologie de traitement d'élastomères et de matériaux à composants multiples comprenant les élastomères; elle peut s'utiliser dans de différents processus technologiques, par exemple, dans la transformation de pneus usés d'avions ou d'automobiles lors du recyclage de pneus usés. Les cylindres (6) d'un système de préparation préliminaire du matériau alimentent le matériau (7) destiné à la désintégration (par exemples, un pneu usé d'automobile) dans une filière (5) dont l'orifice (8) possède une ouverture variable. Une compression du pneu se produit, qui permet d'assurer une plus grande rigidité du pneu, et le pneu est acheminé vers un outil de traitement (1). La vitesse de rotation de l'outil de traitement (2) et le nombre de bords de coupe de l'outil de traitement (1) sont choisis de manière à créer dans la zone de traitement des vibrations ultrasonores. On assure en même temps un traitement par ondes de choc de l'outil sur une unité de temps grâce à la variation de la vitesse de rotation de l'outil jusqu'à ce que la fréquence des coups de l'outil corresponde à la fréquence des oscillations propres de la masse traitée. Les produits de désintégration (les miettes chaudes avec des particules de la corde du pneu) sont évacués au moyen d'un ventilateur (9) à destination d'un refroidisseur (10) où ils refroidissement en dessous du point de Curie, puis ils sont acheminés vers un séparateur magnétique (11) à percussion qui sert à la séparation des inclusions métalliques.
