Abstract

L'invention concerne un dispositif utilisé pour la granulation de matières plastiques, en particulier de matières thermoplastiques. Il comprend une hélice à lames qui est montée dans une calotte de granulation traversée par un flux de liquide. Cette hélice à lames se présente sous la forme d'un dispositif faisant avancer le flux de liquide. Lors de la mise en oeuvre du procédé de granulation, le flux de liquide est, au plus tard après la terminaison d'une phase de démarrage, produit au moins principalement par l'hélice à lames.
