Product Description
PET bottle Recycling Washing Line (bottle-to-flake)
The PET bottle-to-flake washing line is a recycling process that transforms post-consumed PET bottles into clean, high-quality flakes.
Before：
After :
Key steps include:
Sorting & Pre-treatment – Removing caps/labels and coarse contaminants.
Crushing – Shredding bottles into small flakes.
Washing – Multi-stage cleaning (hot alkali, friction, floating separation) to remove adhesives, residues, and impurities.
Rinsing & Drying – Purifying flakes and removing moisture.
Quality Control – Metal detection, color sorting, and filtration for purity.
End Applications of recycled PET Flakes:
Textiles – Polyester fibers for clothing, carpets.
Packaging – Strapping, sheets, non-food containers.
Industrial Uses – Automotive parts, construction materials.
Customers can have PET bottle crushing washing recycling machine line to produce high quality PET flakes for selling, drawing filament, producing PET particles or blowing bottles.

Components of PET bottle Recycling Washing Line:
| Belt conveyor
Belt material: Rubber/PVC/Metal chain. Equipped with wheels for easy moving, with tightening device.
|
 |
| Bale Breaker (opener)
opens the tight bales of PET bottles
|
 |
| Trommel screen (Rotary-drum separator )
Separates stones, caps, sands, any possible contaminates off. |
 |
| Label remover
Dry friction system. Removes 80-90% of labels and caps before crushing. |
 |
| Sorting belt with metal-detector
Removal of non-PET materials (PVC, metals, colored bottles) Detects and removes metal flakes, prevents from getting into crusher chamber. |
 |
| Granulator / Crusher with force feeder
Grinds PET bottles to 12-20mm flakes. Improved knife structure, higher output, wet crushing. |
 |
| High speed Friction washer
Removes stubborn contaminants by friction scrubbing and flushing water.
|
 |
| Flotation washing tank (Sink-Float Tank)
Gravity/density separation. Separates PET (sinks) from PVC/PE (sink). |
 |
| Hot Washing machine/ steam washer
Temperature: 85-95°C Detergent/soda concentration: 1-3% Removes surface dirt (oil/glue) and adhesives. Mechanical agitation for deep cleaning. Heat up by gas/diesel/petrol/LPG |
 |
| Horizontal dewatering machine ( Dehydrator / Centrifugal dryer)
Rotation speed: 1500 RPM Moisture reduction to 0.5-2% Removes alkaline liquid (in the middle of line). Removes surface water from PET flakes (at the end of line). |
 |
| Hot-air dryer
Electrical heater. Final moisture: <1% |
 |
| Zig-Zag Label separator with rotary valve (Air classifier)
Further removal of labels and dust. |
 |
| Electrical Control cabinet
Control and monitors the whole PET bottle washing line. |
