PET bottle washing line is the ideal solution for your PET recycling needs. This fully automated washing line takes compacted bales of PET bottles and turns them into clean, contaminant-free PET flakes that can be used in producing polyester staple fiber or pelletized into granules for use in manufacturing other PET products.

This is accomplished by the implementation of a series of recycling machinery. Our standard PET washing line ranges from an input capacity of 500kg/h upwards to 5,000kg/h. The output capacity is based on the amount of contamination in the PET bottles you’re recycling. While our standard PET bottle washing line is sufficient for most plants, custom setups with additional machinery and increased capacity can be designed for your specific needs.

PET Bottle Washing line Processing:

Debaler Machine: The first step in our PET washing line is to break the compacted bales of PET bottles into a free flowing stream. Once the bales are “busted”, the bottles will move onto the next machinery using a conveyor system.

2. Trommel: An optional piece of equipment, the trommel is a slowing rotating tunnel lined with small holes. The holes are slightly smaller than PET bottles, therefore, small pieces of contamination (such as glass, metals, rocks/dirt, paper, etc…) will fall through while the PET bottles move onto the next piece of machinery.

3. Wet Granulator: Often referred to as a “crusher”, our wet granulator cuts the PET bottles into flakes, or small pieces between 10-15mm in size. With water constantly sprayed into the cutting chamber, our wet granulation process also pre-treats and partially cleans the PET flakes before moving onto the next piece of equipment.

4. Label remover: label remover is a way to separate lighter materials from heavier ones. The main purpose of using it is to remove paper/cardboard contamination as well as plastic films from labels on the bottles.

5. Sink / float Separation Tank: Using water as a medium, materials that float are separated from materials that sink. In the case of PET recycling, PET plastic will sink while plastic films (bottle labels) and PP/PE plastic (the type of plastic used for bottle caps) will float. A screw conveyor at the bottom of the sink/float separation tank will move PET plastics to the next piece of equipment.

6. Hot Washer (boiler): Hot washed PET flakes are of higher value because this process dissolves glues (used to glue labels onto the bottles) and leftover beverages/foods that are difficult to remove in a cold wash process. Often times, additional chemicals and washing agents are added for better results.

7. Friction Washer: A efficient piece of cold water washing equipment, the friction washer uses friction as a mechanical way to remove any hard to remove dirt and debris from the PET flakes.

8. Dewatering Machine: The first step in the drying process, our dewatering machine uses centrifugal force to remove a large portion of water within the PET flakes before moving forward onto our thermal dryers. As thermal dryers require more energy consumption during operation, the use of the dewatering machine will help you save on energy cost in the long run.

9. Thermal Dryer + Cyclone Separator: PET flakes are vacuumed out of the dewatering machine where it’ll travel down a series of stainless steel tubes where the flakes will mix with hot air. The remaining moisture is dehydrated in this process which ends with a cyclone separator. The cyclone separator allow the PET flakes to mix with a fresh stream of cold air which prepares it for storage into the product silo. The cyclone separator is also effective in removing fines and such dust.

10. Product Silo: A storage tank for the clean, dry PET flakes.

11. Pelletizer / Extruder: PURUI recycle machine offers both single-screw extruder and twin-screw extruders. Based on your requirements, we offer both one-stage and double-stage pelletizing setups where granules can be formed using a granulator or water-ring cutting/underwatering cutting system.

12. Final flakes grade as 3A

Final Product of PET FLAKES

PET washing line produces high-quality PET flakes that are not only clean, but are also contamination free. In order to continually improve our washing equipment, we constantly seek customer feedback as well as request samples of PET flakes from customers using our washing lines. The samples are then sent to our laboratories for testing. Based on the many samples we received last year, we are confident our PET washing lines can achieve the following benchmarks:

1. Moisture: < 1-2%

2. Bulk Density: < 0.3G/CM3

3. Total Impurity: < 320ppm

§ PVC Content: < 100ppm

§ Metal Content: < 20ppm

§ PE/PP Content: < 200ppm

4. Particle Size: < 14-16mm


Depending on contaminants within the PET bottle bales, additional equipment maybe required such as a separation table for manual sorting, metal detectors and removal, PVC heat separation, and more. PURUI offers custom tailored PET washing lines based on your specifications. Let us know your needs including capacity, type of PET bottles and how it is packaged, and types of contaminants you are expecting and let our professional team of engineers handle the rest.
