Description
Our standard PET bottle washing line provides a complete solution for transforming dirty bales of PET bottles into clean PET flakes ready for producing polyester staple fiber or further processing into plastic granules through pelletizing. ASG Machine offers standard washing capacities from 500kg/h up to 3000kg/h and can also manufacture custom wash lines with greater capacities to meet specific operational requirements.
Our PET recycling line operates fully automatically, with each piece of recycling machinery connected via belt or screw conveyors. The entire washing line is controlled through a central electric control panel and cabinet, ensuring seamless operation and monitoring.

Debaler Machine – As PET bottles (with caps & labels) often arrive in compacted bales tied together with metal wires, the first stage involves converting the material into a “free flowing” stream. The debaler breaks apart these bales, allowing the plastic bottles to drop onto a belt conveyor that transports them to the next processing stage. Learn more about our debaler machine.
Trommel Separator – A large, slow-rotating machine designed to remove small contaminants. The core component of the trommel separator is a large mesh screen tunnel that rotates at 6-10 revolutions per minute. The holes in this tunnel are sized to prevent PET bottles from falling through while allowing small particles of contamination to pass through. Learn more about our trommel separator.

Wet Granulator / Crusher – The bottles are cut into “flakes” or small pieces via our wet granulator. This equipment utilizes an open rotor mounted with heavy-duty knives that spin at high speeds. As PET bottles enter the granulator’s cutting chamber, these rotating knives interact with stationary knives, cutting the bottles into small pieces. A screen with holes between 12-18mm in diameter controls the size of the flakes; the PET plastic continues to be cut within the chamber until it becomes small enough to fall through the screen holes. Throughout this process, water is sprayed into the cutting chamber, partially washing the bottles while acting as a lubricant to reduce friction between the knives and plastic. Learn more about our wet granulator.
Label Separator – The material stream exiting the granulator consists of PET flakes, paper, and PP/PE/PVC film from labels, along with PP/PE rigid plastics from bottle caps. This mixed stream then enters the label separator, where a column of pressurized air blows away the lighter paper and plastic film into a separate collection tank. Learn more about our label separator.
Sink / Float Separation Tank – A large water tank that separates materials based on buoyancy. This final separation equipment in our PET bottle washing line effectively removes remaining plastic films from labels and PP/PE bottle caps. Since both labels and bottle caps float in water while PET flakes sink, the PET flakes can be easily extracted for further processing. Learn more about our sink float separation tank.
Hot Washer For PET Flakes – Functioning similarly to a washing machine, this equipment washes the stream of PET flakes using boiling hot water, which sterilizes the material and removes contaminants such as glues (from labels), grease/oils, and difficult-to-remove beverage or food residues. Learn more about our Hot Washer For PET Flakes.
Friction Washer – A secondary friction washer using cold water serves to cool and further clean the PET flakes through a scrubbing action. Learn more about our friction washer.

High Speed Dewatering Machine – The dewatering machine utilizes centrifugal force to remove a significant portion of water from the PET flakes. This energy-efficient method partially dries the PET flakes before final thermal drying, which consumes substantially more energy. Learn more about our dewatering machine.
Thermal Dryer + Cyclone Separator – The partially dried PET flakes undergo complete drying in our thermal dryers. Within the long tubes of these dryers, hot air mixes with the PET flakes, removing residual moisture. The final cyclone separator then combines the hot, moist air with a flow of cold air, cooling the PET flakes in preparation for storage. The cyclone separator also serves as the final defense against fine particles such as dust. Learn more about our thermal dryer.
Product Silo – A large storage tank designed to hold the clean, dry PET flakes before further processing or shipment.
Pelletizer / Extruder – Since most PET bottle recycling lines produce clean flakes for direct use in manufacturing polyester staple fiber, we offer pelletizing equipment as an optional component in our washing line. ASG Machine provides both single-screw and double-screw extruders for this purpose. Learn more about our pelletizing equipment.

PET Flakes
We understand the importance of producing high-quality PET flakes that are not only clean but also low in contamination. To continually evolve and improve our PET bottle washing lines, ASG Machine has implemented a customer feedback system where samples of PET flakes from customers using our washing lines are collected and tested in our laboratory. Based on the numerous samples we received last year, we are confident our PET washing lines can achieve the following benchmarks:
- Moisture: < 1%
- Bulk density: < 0.3G/CM³
- Total impurity: < 100ppm
- PVC content: < 40ppm
- Metal content: < 10ppm
- PE/PP content: < 50ppm
- Particle size: < 14-16mm
Please contact us if you have additional requirements.
Custom PET Bottle Recycling Lines
Depending on contaminants within the PET bottle bales, additional equipment may be required, such as a separation table for manual sorting, metal detectors and removal systems, PVC heat separation, and more. ASG Machine offers custom-tailored PET washing lines based on your specifications. Let us know your needs, including capacity, type of PET bottles and their packaging, and the types of contaminants you expect. Our professional team of engineers will handle the rest.
