Twin-screw extruder is extruding and rotating, it is based on the collision between the screws. The mechanical extrusion and rotating system is also extruded according to each group of structures. For the extrusion of the twin-screw extruder How much do you know about the structure of the press-rotation system?


  1. There are two screws in the barrel of the twin-screw extruder, and the feeding part uses a screw to force the material into the barrel. The specifications and layout of the screw bearings are more complicated.

  2. Extrusion system: The tooth shape of the twin-screw screw in the twin-screw extruder does not conform to the rules, and cannot form a closed meshing line, which is a non-sealed type. The screw is self-locking, driven by gears, and the master and slave screws are not in direct contact; the barrel structure is a metal barrel, which has properties such as heat resistance, wear resistance, and corrosion resistance. The cooperation of the barrel and the screw realizes the crushing of plastics.

  3. The function of the transmission structure system is to drive the screw and supply the torque and speed required by the screw during the extrusion process. The axial force generated by the twin-screw during extrusion is similar to or higher than that of the single-screw during extrusion.
