Abstract (en)
[origin: EP0273018A2] 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), and of a sorter (3,4) consisting of another rotor (3) and another stator (4), and said stator (4) of the sorter is formed to be sieve-like, and said means comprising a pulp feed (4), 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 rotors (2,3) of the defibrating means (1,2) and of the sorter (3,4) are only connected to each other with a common shaft, and that the stators (1,4) are separate, and said stators (1,4) and rotors (2,3) are located in the same pulp space (5).
