Introduction of parts of PSD Twin Screw Extruder



PSD Twin Screw Extruder adopts modular design principle, component standardization manufacturing, which can present stable and reliable performance. Thanks to the modular principle, PSD extruders can provide highly customizable solutions according to customers' process and special requirements. Based on different output torque grade, PSD series extruders have basic type and efficiency type.

Process section includes barrels, screw shafts, screw elements, individual temperature heating and cooling unit. Barrels and screw elements are designed in block principle.

Block structure allows the screw elements combine and sequence optimized to realize the process:

Conveying-Plasticization- Compounding & Dispersion- Homogenization- Degassing- Pressure building
Also Block structure allows the barrels adjust freely to the fit the process requirement.

Based on different process position, PSD extruders have different barrels type: feeding barrel, side feeding barrel, close barrel, open on top barrel, vacuum vent barrel, etc. According to the different jobs' requirement, barrels' materials can be nitride steel or bimetallic steel.

Multiple cutting systems can be combined with PSD Twin Screw Extruder, such as strands pelletizing, hot-face cutting and under-water pelletizing, etc.

Both Instrument control and PLC control are available to apply in the PSD electrical controlling system. All the key electrical parts adopt European brands to guarantee the controlling system with significant and stable performance.
