Equipped PP polymerization reaction device adopts the Italian Spheripol process, based on which its capacity is increased by client’s own independent technical strength.
The increased 80,000 tons/year accordingly will be accomplished by USEON SAT-175 co-rotating twin screw extrusion compounding and granulation unit.
This unit applies linear layout, with the delivery scope ranging from the inlet of the hopper to the outlet of the classifier.
SAT-175 co-rotating twin screw extruder, equipped with 2000KW Siemens as the main motor, independent-developed high torque gearbox with its torque up to 12Nm/cm3 and German Nordson underwater pelletizing system.
PCW system and classifier are located respectively on the 3rd and 2nd floor platforms, first connected to the buffer silo then to the external finished product silo.
