Twin screw

Technology for the future

Materials are filtered by a continuous screen changer with a fineness of 150 - 500 µm. Depending on the viscosity of the material, underwater pelletization yields granules between 2.4 and 4 mm.

The machine is specially designed for polyolefins. Four gravimetric weigh feeders are supplied with material via suction conveyor stations and bag chutes. These are located above a side feeder for (mineral) fillers and a weigher for pre-blends with several components. The materials are deaerated via two atmospheric extractors and a vacuum extractor.


  • Filler is metered via the side feeder
  • Melt filtration possible
  • Low-viscosity materials (MFI up to approx. 40 g/10 min)
  • Granulation under water
