Abstract

PURPOSE:To provide the titled kneader extremely reduced in bending stress exerting on each rotor and to enhance durability thereof, by providing a groove enlarging the opposed interval of the top part of a kneading blade and the inner surface of a chamber to a predetermined place in an axial direction corresponding to the connecting part of the feeding blade part and a return blade part in the chamber. CONSTITUTION:A material to be kneaded and continuously supplied into a chamber 1 from a hopper 11 is fed to a kneading part 22 through a feed part 21 with the rotation of rotors 2, 2 and, while stirred and kneaded in the kneading part 22 by a kneading blade 24, shearing action is imparted to said material to be kneaded between the top part of the blade 24 and the inner surface of the chamber 1 as well as in the mutual space between both rotors to gradually plasticize and melt the same. In this case, in the side of the central space between both rotors 2, 2, the pressure of the material to be kneaded and the repelling force to the rotors 2 corresponding to said pressure are released. On the other hand, because the material to be kneaded in the forward side in the rotary direction of the blade 24 escapes to a circumferential side through a groove 25 even at the positions in opposite sides with respect to said central space 14, the pressure exerting on the material and the repelling force corresponding thereto are made sufficiently small and the imbalance of the pressure and the repelling force is reduced thereby to reduce the bending stress of each rotor 2.
