Abstract

A means for dispersing paper, cardboard and pulp, comprising a basin (1) open on top, into which the raw material to be dispersed is fed e.g. from a paper machine located thereabove, and wherefrom it is removed when dispersed with the aid of a pump, and one or several dispersing units (3) placed on the wall (6) of the basin (1), preferably a rotor/rotors. A problem with this kind of apparatus known in the art is that the pulp-circulation effect of the dispersing rotors is poor, whereby the material to be dispersed cannot enter the effective range of the rotors well enough. With the aid of the invention, the problem is solved in that one or several mechanical or flow-technological apparatus (7) providing pulp flow for the rotors is mounted on the wall (5) of the basin (1) opposite to the rotors (3).
