Abstract (en)
[origin: EP0273019A2] A means for defibrating and sorting pulp in paper and cellulose industry, comprising a defibrating means (1,2) consisting of a rotor (2) and a stator (1), wherebetween is established a defibrating zone, and of a sorter (3,4) consisting of another rotor (3) and another stator (4), wherebetween is established a sorting zone, and said stator (4) of the sorter being formed to be sieve-like, and said means comprising a pulp feed (6), accept removal (7) and reject removal (8). At present, defibrating and sorting processes have to be carried out using separate apparatus, which is expensive and space-consuming. With the aid of the present invention, the problem is solved in that the angle ( alpha ) between the centre-line of the shaft (9) of the rotor (2) of the defibrating means (1,2) and the defibrating zone is 5 to 45 DEG and the angle ( beta ) between the sorting zone and the shaft (9) of the rotor (3) of the sorter (3,4) is 75 to 105 DEG , and that the defibrating and the sorting processes take place in the same pulp space (5).
