Abstract

L'invention concerne un appareil et un procédé de traitement d'un mélange de matières particulaires dont au moins une matière thermoplastique, l'appareil comprenant une chambre de mélange (2) dans laquelle se trouve un rotor (4) comportant des bras (6) de rotor assis sur un élément de plaque circulaire (8), lequel fait office de base de la chambre. Un gradin intérieur (10) est fixé à la paroi intérieure de la chambre de mélange (2). Ce gradin (10) dirigé vers l'intérieur définit un périmètre C intérieur circulaire et la base (8) est portée de manière à pouvoir tourner à l'intérieur du périmètre C circulaire défini de manière à laisser un espace relativement réduit (12) entre les surfaces respectives de la base (8) et le gradin dirigé intérieurement (10). Sous la partie rotative de la base (8) se trouve un ventilateur (14) comportant une pluralité de pales, lequel est porté de manière à tourner avec cette partie de la base (8) et à éliminer les matières pouvant passer à travers l'espace jusque dans la région située sous la base de rotation (8), et à ramener ces matières dans la chambre de mélange (2).
