An extruder mixer comprising a hollow cylindrical stator (14) having a cylindrical rotor (10) journalled therewithin, the facing cylindrical surfaces of the rotor and stator carrying respective pluralities of parallel circumferentially extending rows of hemispherical cavities (18, 20). In order to achieve an exponential mixing characteristic in which simple shear mixing is repeatedly interrupted by cutting and turning stages, the rotor and stator cavities (18, 20) are arranged such that (a) the cavities (20) in adjacent rows on the stator are circumferentially offset, (b) the cavities (18) in adjacent rows on the rotor are circumferentially offset, and (c) the rows of cavities (18, 20) on the stator and rotor are axially offset. |
