Abstract

LAS MATERIAS EXTRAÑAS (30, 32/34, 36 Y 24) QUE APARECEN EN UNA DISOLUCION DE PAPELOTE, CON EXCEPCION DE LAS MATERIAS PESADAS NO REUTILIZABLES, SE RECOGEN Y SON CONDUCIDAS A UNO (40) O DOS DISPOSITIVOS DE RECICLAJE (40, 56) CONECTADOS UNO DETRAS DE OTRO. LAS MATERIAS EXTRAÑAS SE SOMETEN A UNA PRIMERA TRITURACION HOMOGENEA (42) PARA PODER SER TRASLADADAS EN ESTADO TRANSPORTABLE EN UNA SUSPENSION, DESPUES SON PREDESINTEGRADAS (46) Y LIBERADAS DE LA SUCIEDAD PESADA (48) PARA FINALMENTE SER FINAMENTE TRITURADAS Y DESINTEGRADAS EN UNA SEGUNDA FASE DE TRITURACION (52). EL DISPOSITIVO DE RECICLAJE (56) SIRVE PRINCIPALMENTE PARA UNA TRITURACION EN BRUTO, ACOPLADA SI FUERA NECESARIO AL TRENZADO (24) EMPLEADO TAMBIEN. LA SUSPENSION DE MATERIAS EXTRAÑAS OBTENIDA EN LA CAJA DE SALIDA, ES REPARTIDA MEDIANTE CLASIFICACION, EN COMPONENTE DE MATERIAL DE FIBRA Y EN COMPONENTE DE MATERIAL DE RESTOS, DE LOS CUALES EL COMPONENTE DE MATERIAL DE RESTOS SE LIBERA DE LAS PORCIONES ESPECIFICAS PESADAS Y LOS TERMOPLASTICOS PRINCIPALES RESTANTES SON SECADOS Y GRANULADOS, PARA PODER EMPLEARLOS DE NUEVO EN LA ELABORACION DE MATERIAS SINTETICAS. EL COMPONENTE DE MATERIAL DE FIBRA, DE FIBRA LARGA OBTENIDO ES TRITURADO SEGUN EL MODO HABITUAL Y ES CLASIFICADO, A CUYO EFECTO PUEDE AGREGARSE, EN FORMA FINAMENTE REPARTIDA, DURANTE LA MOLIENDA, MATERIAL TERMOPLASTICO REGENERADO AL MATERIAL DE FIBRA PARA SU ULTERIOR UTILIZACION EN PAPEL SOPORTE DE CARTON ONDULADO
