Abstract

EN UN PROCESO PARA LA FABRICACION DE UN MATERIAL GRANULAR DE UNA CORRIENTE DE RECHAZO A PARTIR DE UN PROCESO DE RECICLADO DE EXISTENCIAS DE PULPA DE PAPEL GASTADO DE GRADO REVESTIDO, LAS EXISTENCIAS DE PULPA SE SELECCIONAN DE MODO QUE LA CORRIENTE DE RECHAZO PASE A TRAVES DE UNA PANTALLA Y LAS FIBRAS LARGAS SEAN RETENIDAS PARA USO EN LA FABRICACION DE PAPEL. EL MATERIAL SOLIDO EN LA CORRIENTE DE RECHAZO ES SEPARADO MEDIANTE FLOTACION (18). EL AGUA SE ELIMINA DE LA CORRIENTE DE RECHAZO PARA AUMENTAR SU CONSISTENCIA A LA DE ARCILLA DE MODELADO (40). LA CORRIENTE DE RECHAZO SE SUMINISTRA A UN AGLOMERADOR (46) QUE FORMA GRANULOS UNIFORMES DE FORMA IRREGULAR AUNQUE APROXIMADAMENTE ESFERICA. LOS GRANULOS SON ENTONCES SECADOS (50) PARA QUE TENGAN UN CONTENIDO DE SOLIDOS SUPERIOR AL 95%. TAMBIEN SE DESCRIBE UN APARATO PARA LA REALIZACION DEL PROCESO Y CARACTERISTICAS DEL MATERIAL GRANULAR FORMADO MEDIANTE EL PROCESO Y APARATO.
