Typical Processing Flow

 

The exact configuration may vary depending on the feedstock and required flake quality,but a standard line may include:

 

1. Bale Breaker or Bale Opener

   Opens compressed PET bottle bales and distributes the material evenly for subsequent processing.

 

2. Infeed Conveyor and Pre-Sorting Station

   Removes large contaminants,non-PET bottles,metals,stones,and other foreign materials before crushing.

 

3. Label and Cap Pre-Removal System

   Separates loose labels and reduces the amount of label material and cap components entering the washing section.

 

4. Metal Detector or Magnetic Separator

   Removes ferrous and,when required,non-ferrous metal contaminants to protect downstream equipment.

 

5. PET Bottle Crusher

   Reduces whole bottles into properly sized flakes to improve washing efficiency and material separation.

 

6. Pre-Washer

   Removes loose soil,sand,beverage residue,and surface contamination before intensive washing.

 

7. Friction Washer

   Uses high-speed friction and water to remove dirt,paper,adhesives,and other contaminants from the PET flakes.

 

8. Hot Washing System

   Applies heated water and detergent,when required,to remove oil,sugar residue,stubborn adhesives,and organic contamination.Hot washing is particularly useful when producing higher-quality flakes for sheet-grade applications.

 

9. Float-Sink Separation Tank

   Separates PET flakes from materials with different densities.PET sinks in water,while polyolefin materials such as PP and PE caps and rings float and are removed.

 

10. Rinsing and Fine Separation Units

    Reduce detergent residue and remove remaining lightweight contaminants from the PET stream.

 

11. Centrifugal Dewatering Machine

    Removes a significant portion of surface water from the washed flakes.

 

12. Thermal or Hot-Air Dryer

    Further reduces moisture content and prepares the flakes for storage,packaging,or extrusion.

 

13. Air Classifier or Zigzag Separator

    Removes labels,dust,film,and other lightweight materials from the PET flakes.

 

14. Optical Sorting System,Optional

    Can be installed to separate colored PET from clear or light-blue PET and to improve final product purity.

 

15. Final Flake Sorting and Packaging

    Delivers clean PET flakes to a storage silo,bagging system,or direct feeding system for downstream processing.

 

Sheet-Grade PET Flake Quality

 

The sheet grade PET bottle recycling line is engineered to produce PET flakes with the cleanliness and consistency required for sheet production.The final quality depends on the incoming bottle material,sorting efficiency,washing parameters,equipment configuration,and operating conditions.

 

Typical quality targets may include:

 

- High PET purity

- Low PVC contamination

- Low PP and PE content

- Reduced paper,label,and adhesive residue

- Low dust and fine-particle content

- Controlled moisture level

- Consistent flake size

- Improved color separation between clear,light-blue,and mixed-color PET

- Reduced odor and organic contamination

 

For demanding applications,additional optical sorting,advanced hot washing,or specialized flake purification equipment may be integrated into the line.

 

Automatic Control System

 

The automatic control system coordinates the operation of conveyors,crushers,washers,pumps,heaters,dryers,separators,and material handling equipment.A PLC and touch-screen interface allow operators to monitor and adjust:

 

- Motor operation

- Washing temperature

- Water circulation

- Conveyor speed

- Crusher load

- Dryer temperature

- Material flow

- Pump status

- Safety interlocks

- Emergency shutdown functions

 

The system can also provide overload protection,fault alarms,operating-status displays,and production data monitoring.Automatic control reduces labor requirements and promotes stable,repeatable production.

 

Capacity Options

 

The sheet grade PET sheet & bottle washing line is available in a range of production capacities to suit different plant sizes:

 

| Line Capacity | Typical Application |

|---|---|

| 500–1,000 kg/h | Small and medium recycling operations |

| 1,000–2,500 kg/h | Commercial PET recycling plants |

| 2,500–3,500 kg/h | Large-scale continuous production |

| 3,500–5,000 kg/h | High-volume industrial recycling facilities |

 

Actual output may vary according to bottle bale density,contamination level,moisture content,bottle composition,color ratio,and desired finished-flake quality.

 

Advantages for Plastic Recycling Plants

 

Improved Material Recovery

 

The sheet grade PET bottle recycling machine recovers valuable PET from post-consumer bottles and transforms it into a reusable raw material,reducing dependence on virgin resin and lowering the volume of plastic sent to landfills or incineration.

 

High-Efficiency Washing

 

Multiple washing stages remove both loose and stubborn contaminants.The combination of pre-washing,friction washing,hot washing,rinsing,and density separation helps produce cleaner flakes for demanding applications.

 

Reduced Manual Labor

 

Automatic conveying,sorting,washing,drying,and control functions reduce the need for manual handling and support continuous operation.

 

Flexible Raw Material Processing

 

The sheet grade PET bottle washing machine can process PET bottles with different levels of dirt,labels,caps,residual liquids,and color variation.Optional equipment can be added to handle more heavily contaminated material.

 

Stable Output Quality

 

Controlled flake size,multi-stage separation,and integrated drying help provide a consistent material stream for PET sheet extrusion and other downstream applications.

 

Scalable Configuration

 

The sheet & bottle recycling machine can be configured for different capacities,floor plans,water-treatment systems,sorting requirements,and end-product specifications.

 

Recommended Applications for Recycled PET Flakes

 

Clean sheet-grade PET flakes produced by this sheet grade PET bottle cleaning system may be used as feedstock for:

 

- PET sheet extrusion

- Thermoforming sheet

- Packaging trays and containers

- Recycled PET strapping

- Polyester fiber production

- Non-food packaging products

- Injection molding compounds

- PET pelletizing and compounding

- Industrial plastic products

 

Food-contact applications require additional purification,regulatory compliance,and appropriate downstream processing.The PET bottle washing line alone should not be considered a food-grade recycling system unless the complete process is specifically designed,validated,and certified for that purpose.

 

Water and Environmental Management

 

The sheet & bottle cleaning system may be equipped with a closed-loop or semi-closed-loop water circulation system to reduce fresh-water consumption.A typical water-treatment configuration can include:

 

- Sedimentation tanks

- Filtration systems

- Sludge removal equipment

- Water circulation pumps

- Chemical dosing systems

- Wastewater treatment units

- Oil and grease separation

 

Proper water treatment helps maintain washing performance,reduce operating costs,and support more environmentally responsible recycling operations.

 

Installation and Customization

 

The PET bottle recycling line can be customized according to:

 

- Required capacity

- Available factory space

- Bottle contamination level

- Percentage of colored PET

- Desired flake purity

- Required moisture content

- Local power supply

- Water availability

- Automatic sorting requirements

- Finished-product packaging method

 

The plastic sheet recycling equipment may be supplied as a complete turnkey plant or as selected modules for integration with existing recycling equipment.

 

Product Summary
