Definitions

  • the collected white water contains relatively much air, which is why it is reduced in a degassing device 15 to a content of free air of less than 1% by volume.
  • the high-consistency 1 and the low-consistency stream 2 are passed via at least one pump each.
  • the already prediluted high consistency stream 1 is combined with the low consistency stream 2.
  • the low-consistency stream 2 is fed into a low-consistency flow cross-distributor and the high-consistency stream 1 into a high-consistency flow cross-distributor of the headbox 12.

Abstract

La présente invention concerne un système de production d'une suspension de matière fibreuse destinée à la fabrication d'une bande de papier, de carton, de papier-mouchoir ou autre bande de matière fibreuse, à partir d'au moins un flux (1) à consistance élevée contenant de la matière fibreuse et de la matière de charge, dans la partie constante d'une machine de fabrication de la bande de matière fibreuse, au moins un flux (1) à consistance élevée passant par au moins un dispositif de tri (3). Selon l'invention, la complexité du tri est réduite par le fait que la partie acceptée (4) issue du dispositif de tri (3) est introduite dans la caisse de tête (12) de la machine et la partie rejetée (5) par le dispositif de tri (3) est réintroduite en amont dans le flux (1) à consistance élevée.
