A typical PET bottle recycling plant consists of several stages of processing, from collecting waste to creating recycled plastic flakes. Here are the main components and their functions:
- Conveyor belt: Used to feed the waste material into the system.
- Bale breaker: Opens tightly packed bales of PET bottles into individual bottles.
- Trommel screen: Separates heavy contaminants such as stones, caps, sand, and other small debris from the bottles.
- Pre-washer: Uses hot water to pre-clean the bottles before shredding, removing initial contaminants. (PVC bottles may change color after hot water treatment and require further sorting.)
- Label removal: Removes most labels from the bottles before shredding. This machine also has a pre-washing function.
- Sorting conveyor: Manually sorts processed bottles by color, type, and fragment size before pelletizing.
- Metal detector: Detects any metal contaminants that may remain in the bottles.
- Granulator/Crusher: A wet grinding system used to reduce the size of the material and provide initial washing.
- Screw conveyor: Transports the PET flakes.
- High-speed friction washer: Achieves high cleaning efficiency through beaters and sprays. Suitable for washing damaged films and plastic flakes.
- Single or double screw washer: Washes and conveys floating flakes.
- Hot wash tank/steam washer: A hot washing process with caustic soda to remove adhesives and oils.
- Horizontal dewatering machine: Cleans waste plastic after dewatering and mechanical drying. The rotating drum throws plastic and water onto a screen, separating the water. The machine offers high drying efficiency and energy savings.
- Secondary pelletizer (optional): Reduces the size of PET flakes to the final required size.
- Zig-zag label separator (air classifier): For separating individual labels in a shredded form.
- Blowers and transfer silo: Transports material to the storage silo.
- Electrical control panel: Controls the entire system.
The recycled plastic will be fed into a new production cycle as raw material.
