Co-Rotating Extruder


Today technology is improving day by day. Modern gearbox manufacturing is also improving and performing heavier work than their previous versions. Manufacturers use fine steels in gears that can perform better. The extrusion rate is the volume of plastic being extruded from the nozzle. Extruders are used for the conveying high torques to axial. Extruder’s main function is to make the same shape of the material that is softened by the heat. This process is called thermal softening, plasticization, etc.
Types of Extruders
  1. Elastomer extruders
  2. Single screw extruders
  3. Twin screw extruders
  4. Compounding and reclaim extruders
Twin Screw Extruder Gearboxes: In 1972 HENSCHEL developed the first parallel twin screw extruder gearbox. The twin screw extruder gearbox helps to reduce the horizontal and parallel pressure on the shafts. Twin Screw Extruder Gearboxes have high capability to reduce the pressure that is most important in moulding materials and to absorb the axial thrust. During the twin screw extrusion, the machine generates axial forces, which are completely absorbed by these tandem bearings. It also provides high power through compact gearboxes to axial. Twin Screw extruder needs highly sophisticated gearbox to drive the co-rotating extruder screws.
Functions of Twin Screw Extruder Gearbox:
  • They must operate reliably
  • They must transmit high radial loads
  • They must transmit high axial loads
  • They must run smoothly
Advantages of Twin Screw Extruder Gearbox:
  • Robust in design
  • Work with high loads
  • Less noise
  • High boost output
  • Easy replacement
  • Efficient performance
  • High accuracy
  • Efficient transmission
  • Provides more power
  • Thrust bearing
