Unlocking the Mysteries of PET Bottle washing line Technology
The secret to further improving the quality of PET flakes: sorting machines
In a PET bottle washing line, the material sorting machine plays a crucial role in separating off-colors and impurities from the recycled PET material. It uses optical sensors and air flow to detect and remove these unwanted materials. By integrating the sorting machine, the PET material achieves higher purity, fewer impurities, and more consistent color.
This high-quality PET material can be used for the production of recycled plastic products such as bottles, fibers, sheets, etc., meeting industry requirements for quality and sustainability.
The equipment that determines the upper limit of recycling output: PET bottle crusher
The output of PET bottle crusher depends on the equipment specification, driving force and speed, feeding method and system, cutter and crushing chamber structure, as well as the characteristics and processing conditions of PET bottles.
Typically, a PET bottle washing line with an output of 500 kg/hr requires only one NC-800 crusher (cutter shaft length 800 mm).
For outputs above 1000kg/hr, 2000kg/hr or 5000kg/hr, a larger crusher is required.
How does a rinse tank do the job of cleaning PET flakes and separating other impurities?
A rinse tank cleans PET flakes and separates impurities by using water flow and agitation to dislodge and loosen impurities from the flakes. The turbulence created helps separate impurities, high-quality PET flakes will sink to the bottom, while non-PET plastics and other impurities will float to the surface and be automatically salvaged and collected..The process is repeated with clean water for thorough cleaning. The cleaned PET flakes are then dried before further processing.
The secret to fast dewatering and drying of PET flakes: Centrifugal dewatering machines.
A PET flakes centrifugal dewatering machine uses centrifugal force to remove water from the flakes. The wet flakes are loaded into a spinning drum with perforations. As the drum rotates, water is forced out through the perforations, leaving the drier flakes inside. The separated water is collected and drained, and the dried PET flakes are discharged for further processing.

PLASTIC WASHING PROCESS
You may need to know
For a complete PET bottle cleaning line, breaking up the bulk of compacted, packed PET bottles is the first step in the entire washing line. We usually use the Debaler Machine for this process.
The waste plastic bottles enter the Trommel Screen, and during the rotation of the trommel, the debris (glass, metal, sand/soil) attached to the waste will fall out of the screen to increase the efficiency of the subsequent equipment and reduce the loss of the subsequent equipment.
When the PET bottle enters the Label Remover Machine, the sharp, serrated claws inside the label remover tear the label off the bottle as it moves forward, achieving the initial removal of the label. This process can remove at least 95% of the labels.
After a simple treatment, the PET bottles are transferred by a Screw Conveyor to the Plastic Shredder for cutting and shredding.
Typically they are cut into flakes of 12-18 mm size to meet your different PET flake usage scenarios.
After crushing, the flakes will be further washed. They are transferred to the Float Sink Tank, where the PET sinks to the bottom of the float sink tank and is pushed by the screw to the next process.
The flakes with lower density (e.g. PP, PE bottle cap flakes, PVC label flakes) will float.
The drying process of PET flakes is mainly done by Centrifugal Dewatering Machine and Thermal Dryer.
After the flakes are thrown out a large amount of water by centrifugal force, they enter the thermal dryer. The flakes move along the hot air-filled stainless steel tube of the thermal dryer and the dried flakes are finally transferred through the Zig-zag Label Remover for further collection or reprocessing.
Through the above series of steps, you have collected a large, pure PET flake.
You can then use the PET Pelletizing Line to process the flakes into PET granules for sale or for other applications such as injection molding.
You can also use the washed PET flakes directly in the production and manufacture of polyester staple fibers.
