To facilitate the assembly of the screw extruder and to permit repair thereof without a need to replace the entire housing, the mixing elements (9) are provided on split rings (9), which are held axially spaced apart by interposed spacing rings, or which are clamped in position in grooves formed in adjacent annular sections of the barrel.
