The present invention relates to a method and an apparatus for treating waste material, which apparatus comprises a conical rotatable rotor (3) placed between stators (1, 2). At least the stators (1, 2) have recesses (9) by means of which the material in the apparatus can be discharged therefrom when the rotor (3) is rotating. The rotor (3) has several openings (8a, 8b) in the axial direction of the apparatus through which openings at least some of the material is arranged to pass. The edges of the recesses (9) and the openings (8a, 8b) of the rotor (3) are sharp in such a manner that the waste material supplied to the apparatus is ground by means of the sharp edges when it passes through the openings (8a, 8b). |
