PURPOSE:To allow the revolving bodies to have pressing points between the inner wall surface of cylindrical vessel and the inner surface of recessed parts by rotating a rotor in a fixed cylindrical vessel and allowing the rotating bodies received in the recessed parts and of the rotor to revolve and rotate with the rotation of the rotor. CONSTITUTION:A rotating shaft 4 is rotated in the cylindrical vessel 1 provided with a material charging opening 2 on one end and a material discharging opening 3 on the other end. The shaft 4 is fitted with plural rotors 7, 7a-7d, each of which is provided with plural recessed parts on its outer periphery and forms a cylindrical shape as a whole. A rotating body 9 is received in each recessed part of the rotor. The distance between the deepest part of the recessed part 8 and the inner surface of the cylindrical vessel 1 is formed so as to be larger than the diameter of the body 9. As a result, the position of the body 9 is restrained in the pocket, and the pressing points are surely formed between the inner wall surface of cylindrical vessel and the inner surface of the recessed part 8 regardless of the fluctuation of diameter. Consequently efficient kneading is carried out. |
