The first kneading portion (2) disperses a filler in polymer by a powerful shearing force and has kneading blades (12) on its rotor (10). The filler incorporated into the polymer by the first portion (2) is uniformly blended with and dispersed in the polymer by the second kneading portion (4) having cavities (23), (22) in its rotor (21) and stator (20), respectively.
