Plastic bottle recycling line is specially used for crushing and washing waste mineral water bottles, beverage bottles, and other PET plastics.
Plastic bottle recycling line mainly includes de-labeling machine, water bottle crusher machine, sink float plastic separation, frictional washing machine, PET bottle flakes hot washing machine, plastic drying machine, and storage bin, etc. It can be designed and produced in different configurations according to customers’ different requirements.
So how to clean PET bottles achieve the best results? Shuliy Plastic bottle recycling line mainly through the four steps of de-labeling – crushing – washing – drying to clean and recycle high-quality bottle flakes for later reuse.
De-labeling in plastik şişe geri dönüşüm hattı
The first step in the plastic bottle washing line is to de-labeling. The use of de-labeling machine can efficiently remove the bottle’s PVC label.
De-labeling machine using de-labeling cylinders, spindles, and shafts on the moving knife and the cylinder wall of the fixed knife, in the mechanical process the moving knife and fixed knife contact will be stripped of bottles and labels. Then using the agitator and suction separator, the peeled label paper is separated by strong suction.
Crushing in plastic bottle washing line
Due to the large size of plastic bottles, un-crushed plastic bottles cannot be recycled directly. Water bottle crusher machine can easily crush plastic bottles into thin flakes, and this plastic can be easily reprocessed and utilized.
The water bottle crusher machine designed specifically for PET bottle crushing has the features of smooth feeding, stable output, low energy consumption, low vibration noise value, strong structure, low maintenance cost, and long service life.
Washing in PET flakes washing line
- Separation of bottle caps (PP plastic) from bottle flakes is carried out after crushing. Using the lavabo şamandıra plastik ayırma, the bottle cap and bottle flakes can be effectively separated by the sinking and floating method. Bottle caps are floating plastics and bottle flakes are sinking plastics.
- After separating the bottle caps, the bottle flakes are then put into the PET şişe gevreği sıcak çamaşır makinesi for high-temperature steaming. You can put a certain proportion of caustic soda or detergent into the hot washing pot to better remove the oil and other stains on the bottle flakes.
- The next process for the bottle flakes after high-temperature cooking is friction washing. The high-speed frictional washing machine removes impurities and sediment attached to the surface of the bottle flakes.
- Finally, you can use the rinsing tank again to rinse off the residual caustic soda and other impurities on the bottle, and you can get very clean high-purity PET polyester bottle flakes.
Drying in plastic bottle recycling line
The clean bottle flakes are first dried to 95% water using a dewatering machine. If you have higher requirements, you can use the dryer to dry the dehydrated PET polyester bottle flakes to more than 99% through the hot air blower, and then remove a small amount of residual label paper through the air separator.
At this time, the bottle flakes are already high purity, low water, and high-quality PET polyester bottle flakes.
