PEPP Hard Plastic Washing Line | Plastic Recycling Machine
2026-04-28
As the global plastic recycling industry continues to evolve, the reuse of rigid
PE and PP plastics has become a key part of the circular economy. Everyday products such as detergent bottles, chemical drums, hollow containers, crates, pallets, and pipe scraps are commonly made from HDPE, LDPE, and PP materials. If not properly recycled, these plastics create landfill pressure and environmental burdens.
To meet this market demand, Dajiang Machinery’s
PEPP Hard Plastic Washing Line is specially designed for high-contamination, heavy-duty, and high-capacity rigid plastic recycling applications. It integrates crushing, washing, dewatering, drying, and sorting into one automated system.
What is a PEPP Hard Plastic Washing Line?
The PEPP hard plastic washing line is mainly used for recycling:
- HDPE milk bottles / detergent bottles
- PP crates / plastic buckets
- Household chemical bottles
- Blow-molded containers
- Injection molding scraps
- Pipe offcuts
- Industrial rigid plastic waste
The system uses multi-stage mechanical processing to convert waste plastics into materials suitable for pelletizing or remanufacturing.
Core Process Flow
Typical workflow:
- Feeding Conveyor → Crushing → Friction Washing → Floating Separation → Hot Washing (Optional) → Dewatering → Hot Air Drying → Storage
- Feeding Conveyor:A belt conveyor provides continuous feeding, reduces labor cost, and improves workflow stability.
- Crusher Unit:Large containers, buckets, and bottles are shredded into flakes for efficient downstream washing.
- Friction Washer:High-speed friction washers remove dirt, labels, oil, and surface contaminants.
- Floating Tank:Using density separation:PE/PP floats,Metals, stones, PVC sink
- Hot Washing System (Optional):For oil drums, pesticide containers, and chemical waste plastics, hot washing tanks can greatly improve cleanliness.
- Dewatering & Drying:Centrifugal dewatering combined with hot air drying reduces moisture significantly and improves pelletizing efficiency.
Equipment Advantages
- High Automation:PLC centralized control minimizes manual intervention.
- Stable Washing Quality:Multi-stage washing ensures consistent flake cleanliness.
- Energy Saving:Water recirculation lowers freshwater consumption.
- Modular Structure:Can be configured as L-shape, U-shape, or straight layout.
- Easy Maintenance:Wear-resistant components ensure easy maintenance and long service life.
