1.1 Screw Structure
A twin-screw extruder consists of two rotating screws arranged in parallel with the same helix angle. One screw is called the master screw, and the other is called the slave screw. The master screw rolls forward, propelling the material, while the slave screw assists in the transport and mixing of the material.
1.2 Working Process
When the twin-screw extruder begins to rotate, the movement of the master screw propels the material forward along the screw axis. The rotation of the slave screw brings more material into the mixing zone. Due to the synchronized operation of the master and slave screws, the material is effectively mixed and transported within the twin-screw extruder.
