FLOTATION IN RECYCLED FIBRE PROCESS

A multivariabie controller (634) receives from a recycled fibre line at least two measuring results, of which at least one relates to accept measurement and at least one to reject measurement. The multivariable controller (634) controls on the basis of at least one accept-related measuring result an...

Zusammenfassung:	A multivariabie controller (634) receives from a recycled fibre line at least two measuring results, of which at least one relates to accept measurement and at least one to reject measurement. The multivariable controller (634) controls on the basis of at least one accept-related measuring result and at least one reject- related measuring result the mechanical processing of the flotation process and the supply of at least one chemical affecting flotation into the recycled fibre process Selon l'invention, un contrôleur à variables multiples (634) reçoit depuis une ligne de fibres recyclées au moins deux résultats de mesure, parmi lesquels au moins un se rapporte à une mesure d'acceptation et au moins un à une mesure de rejet. Le contrôleur à variables multiples (634) commande, sur la base d'au moins un résultat de mesure lié à l'acceptation et au moins un résultat de mesure lié au rejet, le traitement mécanique du processus de flottaison et l'alimentation d'au moins un produit chimique affectant la flottaison dans le processus à fibres recyclées.
