A comminution plant serving for comminuting material. The comminution plant comprises a set of fixed bottom knifes (12) separated by parallel opening (13), two parallel shafts (6) extending crosswise of the openings (13), a set of upper knifes (10,11) attached on respective shafts (6), the knifes extending partly into the openings (13,-18, 20), and at least one drive assembly (9) for rotating the shafts (6) during operation. The upper knifes (10,11) on one of the two shafts (6) comprise a first upper knife (10) having a first diameter (D') and a second upper knife (11) having a second diameter (d') which is smaller than the first diameter (D'). The upper knifes (11,10) on the other of the two shafts (6) comprise a third upper knife (10) having a third diameter (D'') and a fourth upper knife (11) having a fourth diameter (d'') which is smaller than the third diameter (D''). The first diameter (D') and third diameter (D'') together are of a size which is larger than twice the distance (a) between the axes of rotation (7) of the at least two shafts (6). The comminution plant according to the invention can comminute a material effectively and to high degree of fineness. ® KIPO & WIPO 2008
