Abstract

The object of the invention is a method for processing pulp stock derived from a pulp or paper mill, which pulp stock contains fibres and/or any other components, such as mineral components, in order to disperse the agglomerations in the pulp stock. The method is characterised in that the pulp stock is supplied to an apparatus operating according to the principle of a double action impact mill (the double action impact mill (20)). The apparatus comprises: a first rotor (11) provided with blades; a second rotor (12), which is coaxial with the first rotor and provided with blades and which is arranged to rotate in a direction being opposite to that of the first rotor; and a feeding opening (14) which opens out to the nave of the rotors. Pulp stock is supplied to the feeding opening (14) which opens to the rotor naves and is caused to flow via the blades of the rotors (11, 12) arranged within each other, to the outermost rotor ring, and to be discharged from there as a discharge flow from the apparatus. The invention also relates to an apparatus for performing the method.
