Abstract

A refiner (1) comprises a stator (2) and a rotor (4), The stator and the rotor comprise a flat portion (7, 9) and a conical portion (8, 10). The conical portion has a first end (17) of smaller diameter (D1) and a second end (18) of greater diameter (D2). The refining surface (12) of the conical portion of the stator comprises dams (22) at the distance of five sixths at most of the whole distance (D) between the first and second ends of the conical portion starting from the first end of the conical portion such that at least three fourths of the grooves are provided with dams and that the remaining one sixth of the refining surface comprises dams such that one fourth of the grooves at most are provided with dams. Also a blade segment (19) for a conical portion (8) of a stator (2) of a refiner (1).
