Abstract
A kneading device uniformly kneads materials to be kneaded while efficiently and quickly kneading the materials to be kneaded. A kneading device includes a kneading chamber accommodating materials to be kneaded and a pair of rotors. The pair of rotors is rotated in the kneading chamber and kneads the materials to be kneaded by a plurality of kneading blades. The plurality of kneading blades in each rotor is composed only of inclined blades inclined to the same direction in a rotational direction of the rotor with respect to an axial direction of the rotor when the rotor is developed into a planar state. The rotor has bent blades which are bent at bent portions to change tilt angles with respect to the axial direction of the rotor in the plurality of kneading blades.
