The automatic fibre-grade PET bottle washing recycling line is an integrated plastic recycling system designed to convert post-consumer and post-industrial PET bottles into clean,high-quality PET flakes suitable for fiber production and other downstream applications.The system combines automatic bottle feeding,sorting,crushing,hot washing,rinsing,drying,and material separation in a continuous production line.
Engineered for reliable operation in modern plastic processing plants,the fibre grade PET bottle washing line helps recycling businesses recover valuable PET waste while reducing manual labor,processing losses,and dependence on virgin raw materials.
Product Overview
PET bottles are collected,sorted,processed,and transformed into uniform recycled PET flakes.Through controlled mechanical and washing processes,the fibre grade PET bottle recycling line removes labels,caps,dirt,adhesives,oils,and other contaminants from the bottles.
The resulting fiber-grade PET flakes can be used as feedstock for:
- Polyester staple fiber production
- Recycled polyester yarn
- Nonwoven fabrics
- Strapping production
- PET sheet and thermoforming applications
- Injection molding and other plastic products,subject to final material quality and application requirements
The complete fibre grade PET bottle washing line can be configured according to bottle condition,required output,contamination level,plant layout,and end-product specifications.
Main Processing Stages
1. Automatic Bottle Feeding
Collected PET bottles are loaded into a bale breaker.The automatic feeding system provides a consistent material flow to the sorting and processing sections,helping maintain stable production capacity.
2. Pre-Sorting and Material Separation
Sorting equipment removes unwanted materials before size reduction.Depending on the plant configuration,the sorting section may separate:
- PVC bottles
- PE and PP containers
- Metal objects
- Stones,glass,and other heavy contaminants
- Non-recyclable materials
- Colored or off-specification PET bottles
Manual sorting stations,magnetic separators,metal detectors,and optical sorting systems can be integrated where required.
3. Label and Cap Separation
A label remover machine loosens and separates labels from the PET bottles.Air classification and density separation equipment can further remove labels,caps,rings,and lightweight plastic materials.This improves the purity and appearance of the recycled PET flakes.
4. PET Bottle Crushing
The bottles are processed through a heavy-duty PET crusher equipped with wear-resistant cutting blades.The plastic crusher machine reduces the bottles into consistent-sized flakes,allowing the washing and separation systems to work more effectively.
The cutting system is designed for:
- Stable particle size
- Low dust generation
- Efficient energy use
- Easy blade adjustment and replacement
- Continuous industrial operation
5. Pre-Washing and Hot Washing
The pre-washing stage removes loose dirt,sand,beverage residue,and surface contamination.For more demanding applications,a hot washing system uses heated water and controlled detergents to remove:
- Oil and grease
- Adhesive residue
- Organic contamination
- Beverage residue
- Dirt and grime
- Surface coatings
Temperature,washing time,and chemical concentration can be adjusted according to the incoming PET material and required flake quality.
6. Friction Washing
High-speed friction washers provide intensive mechanical cleaning.The rotating rotor generates friction between the flakes and washing water,helping remove stubborn contaminants and remaining label fragments.
7. Rinsing and Density Separation
Multiple rinsing stages in fibre grade PET recycling machine remove detergent,suspended contaminants,and residual dirt.A float-sink separation tank can separate PET flakes from lighter materials such as PP and PE caps and closures.
Because PET typically sinks while polyolefin materials float,this separation method provides an effective way to improve PET purity.
8. Dewatering and Thermal Drying
After washing,centrifugal dewatering equipment removes excess surface water.Thermal drying systems then reduce the moisture content of the PET flakes to a suitable level for storage,transport,or fiber production.
The drying system may include:
- Mechanical dewatering
- Hot-air drying
- Cyclone separation
- Moisture control
- Dust filtration
9. Fine Separation and Quality Control
Air separators,zigzag classifiers,magnetic separators,and optional optical sorting units can be used to remove remaining lightweight particles,dust,metals,and color contaminants.
For applications requiring higher purity,the fibre grade PET bottle recycling machine can be equipped with additional flake sorting and inspection systems.
10. Automatic Packing
The clean and dried PET flakes are transferred to storage silos or automatic packing stations.The finished material can be packed in woven bags,jumbo bags,or other suitable packaging formats.

Material Quality
When properly operated with suitable feedstock and correctly adjusted processing parameters,the fibre grade PET recycling machine can produce clean,dry,and uniform PET flakes for fiber manufacturing.Final flake quality depends on several factors,including:
- Quality and composition of incoming bottles

- Bottle color and material mix
- Washing temperature and chemical concentration
- Sorting efficiency
- Moisture control
- Flake size consistency
- Required end-use specifications
Additional sorting and purification equipment can be installed when higher purity or improved color consistency is required.
