CLOSED KNEADING MACHINE AND KNEADING ROTOR

摘要

A kneading rotor, wherein the length of a long blade in a rotation direction of a rotor section is greater than one half of the total length of a rotor section main body. Long blades arranged whereby, where a pair of rotor sections arranged in parallel inside a closed kneading machine chamber are rotated in mutually opposite directions, an end section of the long blade of one of the rotor sections on a rearward side, and an end section of the long blade of the other rotor section on a forward side, alternately repeat mutually approaching and separating actions, and in the state of approach, the end sections on the forward and rearward sides oppose each other in the rotation direction on a line linking the respective central axes of the pair of rotor sections, in one cross-section perpendicular to the axial direction of the rotor section.
