The PP PE pelletizing line is a complete plastic recycling solution designed to convert waste polypropylene (PP) and polyethylene (PE) materials into reusable plastic granules, with a production capacity of 100–500 kg/h.
This plastic recycling pelletizing line integrates crushing, washing, dewatering, extrusion, and pelletizing into one continuous system, ensuring stable performance and high-quality output.
It is widely used in recycling plants, plastic factories, and environmental protection industries, making it an ideal choice for businesses looking to produce high-quality recycled plastic granules.
PP PE Pelletizing Process
The complete plastic pelletizing process includes:
- Crushing → reduce material size
- Washing → remove dirt and impurities
- Dewatering → reduce moisture
- Feeding → stable material input
- Extrusion → melting plastic
- Cooling → forming plastic strands
- Pelletizing → cutting into granules
- Screening → uniform particle size
Process flow:
Crushing → Washing → Dewatering → Feeding → Extrusion → Cooling → Pelletizing → Packing
