In the realm of recycling and sustainable practices, the PET bottle washing line stands as a pivotal technology driving the circular economy. This advanced system is designed to efficiently clean and process used Polyethylene Terephthalate (PET) bottles, transforming them from post-consumer waste into high-quality raw material ready for reintroduction into the manufacturing supply chain.
As the demand for recycled materials continues to grow, the role of the PET bottle washing line will become increasingly important, driving innovation and progress in the recycling industry.
MG's PET bottle washing line is a comprehensive, automated process that encompasses several critical stages: bale breaking, pre-washing,
label removing, sorting, crushing, intensive washing, rinsing, drying and storage. Each stage is meticulously engineered to ensure the highest
standards of cleanliness and purity in the final product, making it suitable for a wide range of applications including food and beverage packaging,
textile fiber production, package strap making, and more.
1, bale breaking: usually, the waste PET bottles are pressed in bales package, so the first step of the recycling washing line is to break the bales and
loose the bottles. And horizontal or vertical bale breaker are optional for use at the beginning, chain plate conveyor is the most reliable unit for move
the bales. But for loose bottles, the bale breaker is not necessary.
2, Pre-Washing: Prior to intensive cleaning, bottles undergo a pre-wash to remove loose dirt, labels, and adhesive residues. This step helps to prepare
the bottles for more effective subsequent cleaning processes.
3, label removing: Waste PET bottles are usually covered with half or full labels on the bodies, it’s very necessary to remove the labels well before
crushing and washing process, which can bring the benefits of saving power, water and detergent consumption. We provide dry label remover design
like the single barrel label remover and 3-barrel label remover machine to meet different removing rate and output requests. And wet label remover is
optional for label removing and pre-washing at the same time.
4, Sorting: The initial step involves separating PET bottles from other types of plastic and contaminants. Advanced sorting technologies, such as optical
sorters, utilize cameras and sensors to accurately identify and segregate PET bottles based on color, shape, and material composition. For for lower
investment demand, the manual sorting system provides an economical solution.
5, Crushing: The bottles are then crushed into smaller flakes or chips, which increases the surface area for more efficient washing and reduces the overall
volume for easier handling and processing. Heavy type crusher machines are mostly used in the PET bottle recycling industry.
6, Intensive Washing: This stage employs specialized washing machines that use a combination of hot water, detergents, and
mechanical agitation to thoroughly clean the flakes. The washing process removes oils, sugars, and other residues that may be
present on the bottles. Usually It's very helpful to install a screw friction washer and a washing tank before the hot washer, which
can scatter the PET flakes and separate most float materials like the cap and ring flakes, as well as some remain label.
7, friction washing and rinsing: After the intensive wash, the PET flakes are sent into the high speed friction washing to remove the
tough dirties like glue, then the PET flakes are rinsed with clean water to ensure all detergent residues are removed, leaving the material pristine.
8, Drying: The washed flakes are then passed through a high speed dehydrator machine with 2000rpm rotary speed for dewatering,
the moisture can be less 2 after this machine. For further drying requirement, an electrical drying system is optional, typically using hot air,
to reduce their moisture content to acceptable levels for further processing or storage.
9, storage. After washing and drying ,the clean flakes are usually blown into a big storage silo for easy package of jumbo bags.
Waste plsatic PET bottles
With the development of social economy, a large number of waste plastic bottles are produced in our daily life. And the bottles already make the pollution to the evironment in sea, river and farmland, etc.
PET flakes
How to recycle such waste PET plastic bottles? And what quality PET flakes will you get after the recycling?
For 10s years dvelopment in the waste plastic recycling machine industry, we understand that a good recycling washing line is very important for a plant to solve the plastic bottle pollution and produce high quality PET recycled flakes. Therefore, as a munfaucture the the PET bottle recycling machines, we are keeping on the pursue of the better and better machine technics for the pet washing lines.
Our PET bottle recycling washing lines can help you to produce the qualified PET flakes with the following benchmarks:
Flakes size: < 6-16mm
Moisture content: < 2%
Bulk density: 300±100KG/M3
Total impurity: < 150ppm
PVC content: < 30ppm
Glue and labels: <20%
Metal content: < 10ppm
PE/PP content: < 30ppm
For other requirements on the PET flakes, please contact us freely.
