Co-rotating twin-screw extruder : Due to the co-rotating twin-screw has the opposite speed at the meshing point, one screw pulls the material into the meshing gap, and the other screw pushes the material out of the gap, resulting in material from one screw turns to the other screw and advances in a "∞" shape. Since the gap of the meshing zone is small, the speed of the meshing screw and the groove are opposite in direction, so that the cutting speed is high, and the self-cleaning effect is good, that is, any accumulated material adhering to the screw can be scraped off, thereby The residence time of the material is very short, so the twin screw extruder is mainly used for compounding and pelletizing .

This TSE-75B twin screw extruder is Haisi's 2018 lateset design. From the gearbox, screw elements to the assembling of the extruder is all done by ourselves.
Twin screw extruder is widely used for plastic modification, plastic compounding, masterbatch making, as well as hard plastic recycling, such as PET bottles, TPU wastes, ABS shield, etc.
Here is a site photo of machine test running for PET bottle recycling. The pelletizing method is water strand pelletizing.
