An internal mixer includes a pair of rotors each having spiral vanes adapted to advance materials in the axial direction of the rotors. More particularly, each of the respective rotors has a long vane and a short vane and each of the vanes is of a spiral direction. The spiraling or screwing direction of the long vane is the same as the screwing direction of the short vane on the respective rotors. The flow of the materials along the axial direction differs from one rotor to another. Also disclosed is a mixing and kneading machine including a pair of parallel rotors each having a long vane and a short vane, the long vane extending spirally about the center lines of the rotors and the short vane extending along the center lines of the rotors. Flowing behavior of material to be mixed and kneaded occurs in opposing directions between both rotors. |
