PET Bottle Recycling Machine

The PET Bottle Recycling Machine is designed to wash and clean the recycled PET bottles, such as the mineral water bottles, pesi bottles, oil bottles, etc. The clean recycled PET bottle flakes processed by PET bottle processing machine can be used to produce the polyester staple fiber, PET strap band, granules, PET transparent film and sheets, etc. The top class PET bottle flakes can be used to mould the PET bottles again. We had exported this PET bottle recycling line to Russia, Ukraine, Poland, Saudi Arabia, Africa, etc.

Technique instruction of PET bottle recycling machine

Capacity: 1500kg per hour (for reference, we can adjust the configuration according to your demand of capacity)

1. Label peeling off section

The labels of the PET bottles can be peeled off by the label peeling machine

2. Complete bottle washing section

The PET bottle after label peeling machine will be fed into the complete bottle washing drum by the conveyor. The PET bottle is washed according to the bottle washing technique requirement. The sediment and impurities inside the PET bottles will be pre-washed, and then also remove the residues, such as the trademarks of PE, paper labels and some PVC adhesive label which stays inside the PET bottles. More importantly, after being heated and pre-washed, the PVC bottles change in the physical property (comparatively with PET bottle, PVC bottle changes color to ivory white or light yellow). It is very easy to be selected by follow-up procedure.

PET Bottle Washer

The washing process control and the washing detergent adding are controlled by the PLC computer automatically. According to the configuration of equipment, the washing water is 3 steps washing (for example, the first step washing, the second step washing with detergent, the third step washing is rinse).

3. Accumulating silo section and label blowing section:

The PET bottle after being washed by the complete bottle washing drum will be fed into a accumulating silo for water filtration, and then feeding into the label blowing machine by the conveyor, discharge the residue inside the PET bottles, such as the trademarks and garbage.

4. Manual sorting section:

Manual sorting section removes any other kinds of bottles from the PET bottles, such as, PVC bottle, different color bottles, label debris and garbage, etc. Ensure the transparent PET bottles for the next section. The sorting unit is divided into PVC bottle selecting post, different color bottles selecting post, label selecting post and garbage selecting post, etc. The practice has proved that if there is reasonable division of labor; establish the system of personal responsibility, the manual sorting effect could be better than automatic sorting machine effect.

5. PET bottle crusher section

The PET bottle crusher has the characteristics of smooth feeding, steady operation, low energy consumption, low vibration noise, strong structure, low cost of maintenance and long life, etc. And at the same time, the wet crushing method, use the water impact force strengthen the washing effect of PET debris; it also reduce the friction heat by the water cooling, reduce the PET debris, extend the life of the cutting tools.

6. Float washing section

During the bottle crushing, there are some caps and rings (the material of the caps and rings is PP or HDPE) should be removed. Based of the different density of different plastic (-1.3/ -0.8), water (the density is 1) is the medium. During the float-wash machine operation, the PET flakes sink, the floating caps and rings debris are removed, we can obtain more pure PET flakes.

7. Hot washing, friction and rinse section

This section is to make PET bottle flakes more pure. It mainly relies on the three washing forces: mechanical, chemical and thermal power, after hot washing in the hot washing machine with detergent, after the friction of the high-speed friction machine, and rinsing with clean water in the rinse machining, completely remove impurities in the bottle flakes, such as glue, medicinal liquid and other impurities.

8. Dewatering and color separating machine and finished product storage section

This section will dehydrate the clean PET bottle flakes by the dewatering machine and by hot wind blower. There may be very small percent (less than 1.5%) of other color PET flakes inside the transparent PET flakes. We adopt one color separating machine which removes all of non-transparent PET flakes. The high quality PET bottle flakes (100% transparent) will be delivered to a silo. They are packaged by one automatic packaging machine.

For the washed and dried PET bottle flakes, during the transportation and storage, the material which touched with PET flakes is by stainless steel to ensure PET flakes not being rusted.

9. Water circulation treatment system

The system includes the hot washing unit and washing unit water circulation system. The operation will be done in the closed-circuit system; the system configured with filtration and transportation facilities, to maintain the clean agent purity. Fill detergent liquid in time to maintain the clean agent concentration, and ensure the cleaning effect. The cleaning unit washing water can be reused, and it can lower the water consumption to the most economical level.

10. Electrical control system

The system is to control the bottle washing equipment operation in accordance with the requirements and washing techniques. The equipments can be controlled both automatically and manually by the electrical system. And control the safety production.

Control Panel

After the bottle pre-washing, selecting, crushing, float washing, hot washing, friction washing, rinsing and drying dehydration, color separating, the total content of impurities of PET bottle flakes is down to 100ppm, the PVC content is less than 30ppm. The washed high quality PET bottle flakes can be used to produce filament, chemical fiber, etc. high-grade plastic products.
