    • PURPOSE: To enable the execution of the same self-wiping and barrel wiping actions by providing the subject mixer with mixing bore holes or barrel parts which have the shafts rotating around stationary axial lines of rotation and have the diameters increasing in such a manner that the mixing action is weaker in one portion of the machine. CONSTITUTION: This mixer has a first barrel part which has a pair of the interconnected internal mixing bore holes 14, 15 of a first diameter, drive mechanism 22 to 25 of the shafts 18a, 19a and mixer members 18, 19 which are disposed to face on the shafts described above and to wipe each other and to wipe the interior of the barrel. The mixer is also provided with a second barrel part including the interconnected transition bore holes 42 to 45 of the progressively changing diameter. Further, transition crank parts 63, 64 extending in a radial direction and axial direction and mixing blade parts 54, 55 extending in a radial direction and axial line direction in an opposite direction are provided. These shaft parts and mixing blade parts are formed to a V shape and the blade parts are so shaped as to wipe each other over the entire length thereof and to wipe the large bore holes.
