Abstract

Une méthode hybride de traitement des fibres à papier pour enlever les matières collantes haute densité inclut généralement l'utilisation d'un réseau à plusieurs étages de nettoyage avant couplés à une cellule de flottaison qui augmente l'efficacité globale du système. Dans une forme de réalisation préférée, un premier rejet de flux aqueux d'une première étape de banque d'épurateurs tourbillonnaires est traité dans une cellule de flottaison avant d'être inséré dans une seconde étape de banque d'épurateurs tourbillonnaires. Avec la technique améliorée, les composants acceptés de la première étape de banque d'épurateurs tourbillonnaires peuvent être combinés avec les composants acceptés de la seconde étape de banque d'épurateurs tourbillonnaires et insérés dans un dispositif d'épaississement, par exemple. La technique est aussi employée de manière appropriée pour enlever les matières collantes des matériaux déjà criblés avec une toile métallique fine.
