PURPOSE:To provide the titled kneader capable of increasing a kneading time to a material to be kneaded to carry out sufficient kneading by enlarging an L/D ratio and enhancing the supply force of the material by compensating the lowering of the rotary speed of a rotor with the increase of the L/D ratio by engagement in a feed part. CONSTITUTION:A feed part 5 is formed into a large diameter compared to other parts and supply flights 51 are mutually engaged in said feed part 5. In a first kneading part 6, a rotor 4 has a non-circular cross area and forms an outwardly protruded kneading blade 61 suitable for imparting shearing and stirring actions between the rotor 4 and the inner wall of a chamber 1 and between mutual spaces of the rotor 4. In addition, from the initial end part to the intermediate part of the kneading part 6 in an axial direction, the kneading blade 61 is continued to a sending blade part 62 in such a manner that twist with an appropriate lead angle is formed toward a direction gone away from the rotary direction of the rotor and, from this part to the terminal end thereof, a return blade part is formed so as to provide twist with a lead angle in an opposed direction. Therefore, stirring action is increased with the interference of the material and the generation of pressure. |
