An extruder-mixer has a stator and a rotor which is arranged coaxially with respect to the stator. The rotor is rotatably supported with respect to the stator. The stator is at least partially arranged inside a volume defined by the rotor. The rotor has a rotor cage having a large number of apertures. The apertures are configured to be elongate in a longitudinal direction and the longitudinal direction thereof extends in each case in a skewed manner with respect to a rotation axis of the rotor.
