Plastic PVC transparent pelletizing production line is mainly used to produce CPVC granules, PVC granules, soft PVC granules, and transparent PVC granules. This PVC compounding and granulation production line adopts advanced design concepts to ensure efficient extrusion of PVC materials, combined with a unique plasticizing screw design concept to ensure uniform plastic extrusion and high output.
Process line of Recycled PVC pelletizing line:
Raw material+ additive → Mixing → Conveying feeding → Force feeding → Conical twin screw extruder → Blowing hot-cutting mould → Cyclone separator → Vibrating screener → Blowing system → Storage hopper → Finished product packing
Raw Materials of Recycled PVC pelletizing line:
Pipes,Transparent packaging,Houseware / household products/ household appliances,Fruit box,Beverage bottle,Microwave cooker,Water bottle,Detergent bottle,Personal care packaging
Components of PVC pelletizing line:
A1: Conical twin-screw extruder:
Adopts high-efficiency conical twin screws, specially designed for PVC powder, to ensure uniform plasticization and high extrusion volume. Stable temperature control system can ensure high-quality pipe extrusion. For CPVC materials, the extruder adopts hollow screws, and both twin screws have oil temperature control systems.
A2: Extrusion die:
Special molds for PVC and CPVC materials to ensure extrusion pressure.
A3: Pelletizer:
With hot die face cutter. The pelletizer adopts 4P motor to ensure pelletizing speed. The pelletizing speed is controlled by the inverter
A4: Blowing system:
Two-stage blowing system. The pellets will be cooled during air conveying.
A5: Vibrator:
Used to screen out good pellets.
