Abstract
An extruder mixer for the extrusion of molten plastics and rubbers. The apparatus comprises a hollow cylindrical stator member and a cylindrical rotor member rotatable within the stator. The facing cylindrical surfaces carry rows of hemispherical cavities extending peripherally around the members so that the rows of one member are axially offset from rows of the other member whereby there is an axial overlap of the cavities and rotor. The cavities in adjacent rows on the rotor and stator are also circumferentially offset.
