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?
