Abstract
A method and an apparatus for treating waste material. The apparatus has a conical rotatable rotor (3) placed between stators (1, 2). At least the stators (1, 2) have recesses (9) from which the material in the apparatus can be discharged 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 waste material passes. The edges of the recesses (9) and the openings (8a, 8b) of the rotor (3) are sharp so that the waste material supplied to the apparatus is ground by means of the sharp edges when it passes through the openings (8a, 8b).
