Abstract

To stack and dilute a paper fiber material, with a high consistency, an initial volume (1) is held in a stack for a given dwell time before passing onwards as a second volume (2) to be diluted into a suspension which can be pumped. <??>To stack and dilute a paper fiber material, with a high consistency, an initial volume (1) is held in a vessel in a stack for a given dwell time before passing onwards as a second volume (2) to be diluted into a suspension which can be pumped. A circulation flow (3) with the added water (W) is generated within the second volume by a rotor (4), which carries off the high consistency material from its lower boundary (10). The paper fibers are taken off as a suspension (S) through a sieve (5) carried by a rotor (4). A screw (7) is mounted in front of the rotor, to generate an axial flow (8) in the suspension, away from the sieve. The screw is rotated at the same speed as the rotor.
