Abstract

L'invention concerne un système (10) pour le traitement d'un mélange (12) contenant des matériaux souhaités (14) et des matériaux plastiques contaminants (16) en vue de leur séparation lors d'une étape ultérieure de traitement. Ce système (10) comprend une station de traitement (18), des moyens de guidage (24, 25, 30) permettant de guider le mélange (12) dans la station de traitement (18) et des moyens de chauffage (20) permettant de chauffer un milieu fluide s'écoulant dans la station de traitement (18). Les moyens de chauffage (20) sont disposés de manière que le mélange (12), au niveau de la station de traitement (18), soit chauffé à une température comprise dans une plage de température prédéterminée en-dessous des points de fusion des matériaux plastiques. Après chauffage des matériaux à cette température et exposition de ceux-ci dans la station de traitement (18) pendant un laps de temps prédéterminé, les caractéristiques physiques des matériaux plastiques contaminants (16) se modifient et adoptent une forme permettant leur séparation lors d'une étape de traitement ultérieure. Ce système se prête particulièrement à l'élimination des fibres plastiques des fibres naturelles, notamment la laine, le coton et la soie.
