A refiner (1) includes a driving source (20), a rotating shaft (2) rotated by the driving source, a conical-type (3) rotor attached to the rotating shaft, stators (4) disposed in a casing (C) to face the conical-type rotor. The conical-type rotor has a substantially cone-shape first conical portion (31) and a substantially cone-shape second conical portion (32), and bottom portions of the first and second conical portions are joined together. The rotating shaft passes through top portions of the first and second conical portions, and the conical-type rotor is attached to the rotating shaft. <IMAGE> |
