PET bottle recycling washing line is used for recycling waste dirty plastic PET bottles into clean PET flakes by crushing washing and drying steps, for example, mineral water bottles, cola bottles, juice bottle, oil bottles and PET preforms, etc. The clean PET flakes can be pelletized to the PET pellets for using, or direct usage in polyster fiber production, strap extrusion, container injection and sheet making, etc.
Our PET bottle recycling washing lines have high automation and efficiency on label removing, bottle crushing, flakes hot washing, friction washing and cold washing, dehydrating and storage. The whole processing are controlled by the centralized control system.
1, label remover.
Two type of label removing machine are optional for removing the shrink PVC labels from the PET bottle bodies, one is single barrel type, the other one is 3 barrels type. Alloy blades are assembled on the paddles and barrel with special angles, while the bottles go through the rotary blades and stationary blades, the heads of blades will peel off the labels, and the negative blowers will such out the labels from the barrels. the label removing rate can be up to 99.5% by our bottle label removing machines.
2, heavy crusher (granulator)
For the waste PET bottles recycling, heavy crushers are used for the washing line, it can be used for dry crushing or wet crushing. Alloy for blades such as D2, blade mounting with V angle on the rotor, and 5 groups of rotary blades are installed for crushing the PET bottles with high output, less powder. usually screen sieve with 12-16mm hole diameter are chosen for PET bottle crusher. machinecal or hydraulic system are for opening the top cover of the bottle crushers.
3, hot washer
The hot washer is mainly used for cleaning of tough dirty with chemical assistant. With the stirring shaft, The PET flakes sink in the hot water with detergent for soaking well, so that the dirty can be washed out easily in the next washing machines.
To heat the water for washing, the users can choose electrical heater or gas heater for the hot washer, or supply the hot water from a boiler directly.
The hot washer has two layers design, heat insulation cotton are filled between the two layers. Inner layer are usually made of stainless steel, and with a coil pipe for heat conduction on the inner wall.
Two models of hot washer for the PET flakes washing in our company, one is single shaft type, the other one is 11 shafts type.
The 11 shafts type of hot washer can bring better washing result.
4, friction washer
Friction washers are usually used after the hot washer, it can scrub off the tough dirty from the surface of PET flakes after the hot soaking, for example, label left, glue, mud and oil.
If the tough dirty is less, the low speed frction washer can be used. Otherwise, high speed friction washer must be used in the pet bottle recycling washing line.
5, washing tank
By the washing tanks, the floating caps and labels can be separated from the top, and the PET flakes will sink to the bottom for washing and conveying by the screw.
Stainless steel 304 is used for making the washing tanks, anti-corrosion, rust-proof in long working lifetime.
6, dehydrator machine
Our dehydrators have rotation speed up to 2000rpm, Thus, the PET flakes don't need to be dried again by electrical heater after the dehydrating.
On the Dehydrator, the main shaft is strong with thick paddles, which are changable for easy replacement after wearing.
Stainless steel is used to make the filter sieve and paddles.
7, tiny label separator
After the washing and dehydrating, there are some tiny labels left with the PET flakes, And the zigzag label separator is used to suck out such tiny labels. It a good assist machine for the whole PET bottle recycling washing line.
8, cyclone system
The system consists of blower, pipeline ans storage silo, It is used to convey the clean PET flakes into the silo for temporary storage, waiting for bulk packages or other processing.
Stainless steel is used to make the pipes line and silo.
9, Control cabinet
It's a centralized control system for each machine of the PET bottle recycling washing line. The operator can control and monitor the machine working situation easily on the panel of control cabinet.
Good quality electrical components and parts are used for the cabinet, for example, SIEMENS or SCHNEIDER contactors, ABB inverter, OMRON temperature meters, etc.
Besides the above mentioned important units in the PET washing line, screw loaders and belt conveyors are also required for the machines connection to convey the PET bottles or flakes.
For more, the users also need to have osme other auxiliary machines as following:
1, Debaler: the debaler for breaking the packing belts of the PET bottle bales, loose the bottles for easy processing and recycling.
2, trommel: filter out the small sands, metal and soil from the barrle holes while the rotating.
3, color sorter: it's used for the separating of different color flakes.
4, waste water treatment system: if the PET recycling plants have waste water treatment system, the dirty water can be treated for recycling after the washing, and the treated water can be reused for the whole PET bottle recycling washing line.
etc.

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.
