Abstract (en)

[origin: WO2009089878A1] The invention relates to a pulper for pulverizing and suspending paper material (S), having a container (1), which is open on top, and in which the paper material (S) can be mixed with water (W), pulverized, and suspended, so that a suspension (P) containing paper material is formed, wherein a driven rotor (2) is located on the base of said container (1) to generate a circulation flow in said container (1). To this end, the efficiency of the pulper is to be improved in that a vertical flow barrier (8, 8', 8'') is used on the side wall (5) of the container (1).
