Common Questions About Industrial Three Stage Plastic Granulating Line
Q: What is Three Stage Plastic Pelletizing Line?
A:
A three-stage plastic pelletizing line is an advanced plastic recycling system that uses three connected extrusion stages to melt, filter, degas, and pelletize plastic materials with higher stability and better pellet quality.
Compared with single-stage and double-stage systems, the third extrusion stage provides stronger degassing, more stable filtration, and improved melt homogenization, making it especially suitable for processing wet, heavily contaminated, or difficult-to-recycle plastic materials.
The first extrusion stage mainly performs:
- Material feeding and plasticizing
- Initial melting and compression
- Primary degassing
The second extrusion stage improves:
- Melt filtration
- Pressure stability
- Material homogenization
The third extrusion stage further enhances:
- Deep degassing performance
- Moisture and volatile removal
- Melt purity and stability
- Final pellet appearance and density
Q: What is Three Stage Plastic Pelletizer Line Price
A:
The three plastic pelletizer line price is About USD 30,000–70,000 depending on material, capacity and configuration.
Q: What is the Working Process of Three Stage Plastic Pellet Making Machine?
A:
Material Feeding → Extruder → Hydraulic screen filter changer → (Second stage extruder → Hydraulic screen filter changer) → (Third stage extruder → Hydraulic screen filter changer → Die head/Water Ring cutting ) → Water cooling → Dryer → Vibrating Screen → Storage Hopper
