Abstract

Une méthode dadaptation dun procédé de fabrication de pâte à une chaîne de modifications de production comprend : le changement de la structure dun raffineur à disque à un raffineur à cône à disques; le changement de la structure du bâti de sorte que la chambre du raffineur du raffineur à cône à disques comprend un rotor avec une section de surface de raffinage conique; le retrait dun élément dextrémité dune connexion avec la structure du bâti du raffineur à disque; lagencement dans le rotor dun élément rotor comprenant une section de surface de raffinage conique; lagencement en connexion avec lélément dextrémité dun stator qui comprend une section de surface de raffinage conique; lagencement dans la structure du bâti, en connexion avec le cadre de pression, un manchon dextension ou une structure dextension pour accroître létendue de la chambre de raffinage dans une direction de larbre du raffineur à cône à disques; et la fixation de lélément de fixation en connexion avec le cadre de pression de sorte que le manchon ou la structure dextension reste entre lélément dextrémité et le cadre de pression.
