Abstract

UN APARATO PARA LA RECUPERACION DE RESIDUOS HETEROGENEOS CONSTITUIDO POR DOS O MAS MATERIALES PLASTICOS POSEE UNA FASE DE MEZCLADO EN FRIO EN LA QUE LA MASA HETEROGENEA, PREVIAMENTE TRITURADA, SE SOMETE A UN MEZCLADO COMPLETO PARA OBTENER UNA MEZCLA UNIFORME. ESTE TRATAMIENTO SE EJECUTA EN UN MEZCLADOR DE HELICE (100) CUYA ZONA CENTRAL (102) POSEE SECCIONES DE ROSCA HELICOIDALES (104) DE SENTIDO DE GIRO CONTRARIO ENTRE SI. LA MASA HOMOGENEA MEZCLADA OBTENIDA SE SOMETE POSTERIORMENTE A UN TRATAMIENTO TERMICO EN OTRO TRANSPORTADOR DE HELICE CUYA PARTE CENTRAL POSEE UNA SECCION DE DIAMETRO GRADUALMENTE CRECIENTE SEGUIDA DE UNA PRONUNCIADA DISCONTINUIDAD DESTINADA A INCREMENTAR LA DESGASIFICACION DEL MATERIAL SOMETIDO AL TRATAMIENTO TERMICO.
