ABSTRACT:
Waste paper is defiberized within a container or receptacle in a thick stock range at a low water level. Thereafter, by further infeeding water, the obtained slurry or the like is diluted to a consistency of less than 7% while continuing the defiberizing operation. Finally, the obtained stock suspension is withdrawn through a sieve or screen located at the floor of a defiberizing container. The defiberizing container or receptacle used for performing the method possesses a lower region having a smaller diameter, above which there is located an upper region having a larger diameter.
