Abstract (en)
[origin: WO2014023692A1] The invention relates to a broke system for the treatment of broke of a machine for producing a paper, cardboard, tissue or another fibrous web, wherein the broke is broken down in at least one mechanical pulper, and the fibrous stock suspension which is produced in the process is collected, downstream of the mechanical pulper, in at least one feed store (1) and is subsequently guided through at least one cleaning device (2) and a plurality of defibring devices (3, 4). Here, a high efficiency of the defibring is to be achieved by virtue of the fact that, downstream of the cleaning device (2) and at least one following coarse defibring device (3), the fibrous stock suspension is guided into at least one recirculation store (5) which is followed by at least one fine defibring device (4) and into which at least part of the fibrous stock suspension which leaves the last fine defibring device (4) is returned at least temporarily.
