Abstract
A kneaded product of a desired state of kneading is available by causing a material to be kneaded to flow in tip clearances between rotor segments 1b and 1b of screw sets 1 and 1 and an inner wall surface of a chamber 4 while rotating the screw sets 1 and 1 provided to the right and the left of the chamber 4, and imparting a shearing force for dispersion. Each rotor segment 1b has a plurality of kneading blade 7 having different distances between the segment center and the top, so as to achieve a plurality of tip clearances different at least in the circumferential direction when the segment center is aligned with the chamber center.
