摘要： An extruder for feeding material and for removing gas from the fed material. The extruder includes a vent block positioned between a first and second auger. The vent block including a vent cavity having a feed end and an exit end, an inner feed ring that partially extends into said vent cavity at the feed end of the vent cavity, and a screw element rotatably positioned in the vent cavity. A front portion of the outer ring is longitudinally aligned with or overlapping the front end of the inner feed ring. The outer ring forms at least one gap or opening at or adjacent the feed end of the vent cavity to enable gas to flow out of the vent cavity as material is moved though the vent cavity from the feed end to the exit end by the screw element.

摘要： A processing installation for devolatilization of polymer melts comprises a first extruder and a second extruder arranged downstream thereof in a direction of conveyance. The first extruder comprises several rotatably drivable first shafts which are provided with first treatment members and several devolatilization zones with associated devolatilization ports. Correspondingly, the second extruder comprises several rotatably drivable second shafts which are provided with second treatment members and several second devolatilization zones with associated devolatilization ports. The first treatment members have an external diameter which is smaller than or equal to that of the second treatment members. A devolatilization unit is arranged in a transfer zone which interconnects the extruders. The devolatilization unit comprises a perforated plate and a clearance arranged downstream in the direction of conveyance. A control unit is configured in such a way that when the processing installation is operated, the speed of the second shafts is lower than the speed of the first shafts. The processing installation allows a high devolatilization performance and a high polymer throughput to be achieved at the same time. A throttle is arranged in the transfer zone upstream of the devolatilization unit when seen in the direction of conveyance, with the position of the throttle being adjustable by means of the control unit.
