Common Questions About Industrial Two Stage Plastic Granulating Line

Q: What is Two Stage Plastic Pelletizing Line?

A:

 

A two-stage plastic pelletizing line is a recycling system that uses two connected extruders to melt, filter, degas, and pelletize plastic materials more efficiently and stably than a single-stage system.

The first extrusion stage is mainly responsible for:

  • Feeding and plasticizing the material
  • Initial melting and degassing
  • Removing moisture and volatile gases

The second extrusion stage further improves:

  • Melt homogenization
  • Filtration stability
  • Degassing performance
  • Final pellet quality and consistency

Compared with a single-stage pelletizing machine, a two-stage system is better suited for processing plastic materials with:

  • Moisture residue
  • Printing ink
  • Dust or light contamination
  • Mixed or unstable material quality

It is widely used for recycling:

  • PE/PP film flakes
  • Washed agricultural film
  • PP woven bag flakes
  • BOPP printed film
  • Soft plastic regrind materials

Main advantages of a two-stage pelletizing line:

  • More stable extrusion pressure
  • Better degassing efficiency
  • Higher-quality plastic pellets
  • Improved filtration performance
  • Reduced black spots and air bubbles

A two-stage pelletizing line offers an ideal balance between pellet quality, operating stability, and production cost, making it one of the most popular solutions in plastic film recycling.

Q: What is Two Stage Plastic Pelletizer Line Price

A:

The two stage plastic pelletizer line price is About USD 20,000–60,000 depending on material, capacity and configuration.

Q: What is the Working Process of two stage plastic Pellet Making Machine​?

A:

Material Feeding → Extruder → Hydraulic screen filter changer → (Second stage extruder → Hydraulic screen filter changer → Die head/Water Ring cutting ) → Water cooling → Dryer → Vibrating Screen → Storage Hopper 

Q: What is Suitable Raw Materials for tow stage plastic pelletizing machine the

A: 

Suitable for PP, PE, PET, ABS, HDPE, PS, film scraps, rigid plastics, and washed flakes.
