Twin screw extruder BTS

The twin screw extruder is developed for directly processing of polymers without the energy-intensive pre-drying process or special processes

  • When compared to single screw extruders, improved feeding performance when processing raw materials with low bulk density such as PET flakes from edge trims or bottle recycling
  • Barrel and screws can be adjusted to the process specifications by way of our module construction method
  • The wide selection of materials that can be used for screw and cylinders allows the processing units to be optimised for processing raw materials that are prone to wear and tear and/or corrosion
  • The spectrum in installation sizes comprises screw diameters from 45 up to 120 mm with process lengths of up to 44 D

Other sizes and lengths as well as customised machinery can be realised upon request.
