counter-rotating twin-screw extruders are widely used in extrusion molding and batch granulation.
Tightly meshing counter-rotating twin-screw extruder for PVC profile extrusion
The shear rate is limited to [γ] = 6 to 8S-1. The maximum linear speed of the screw
V=7～8m/min for the maximum linear speed of the screw when it is extruded from PVC pipe
V = 10 to 12 m/min. Therefore, it is often operated at a lower speed.
Meshing co-rotating twin-screw extruder, widely used in polymers
Modification: blending, filling and fiber reinforcement, compounding or mixing. also may
Used for extrusion of shaped articles, but rarely used to process profile products.
The allowable shear rate is around [γ] = 60 to 140 S-1.
The screw line speed V=30～50m/min,
The maximum V = 160m / min.
High-speed meshing co-rotating twin-screw extruders are commonly used for materials
The compounding and extrusion and venting operations as a continuous chemical reaction. This type of squeeze
The speed of the output is in the range of 300 to 600 r/min.

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.
