Abstract (en)
[origin: WO0053390A1] A single rotor extruder for an elastomeric or plastics medium has a casing (2) in which an extruder screw (1) works with a Transfermix section and includes a gear pump comprising a casing and at least two gear wheels (5, 6), the gear pump casing being integral with the casing (2) of the extruder, and one gearwheel (5 or 6) of the gear pump being coaxial with the extruder screw (1). The gear pump is integrated with the extruder screw, which has advantages in controlling the temperature, output and throughput of the medium. The gear pump may be arranged before or after the extruder screw (1).
