How does PET recycle pelletizing machine work?

Publish Time: 2021-08-11     Origin: Site

The PET recycle pelletizing machine has the characteristics of high speed, high shear, high output, good exhaust effect, and low energy consumption. The PET recycle pelletizing machine can process the used PET bottles after crushing, washing, and spin-drying processing to meet the requirements of net flakes, and can be directly drawn (granulated) for remaking PET-related products. Then, let's introduce in detail How does PET recycle pelletizing machines work?


Here is the content list:

  • The barrel of the granulator

  • Automatic temperature setting

  • Process of PET Recycled Granulator


Screw of granulator

The PET recycle pelletizing machine changed the design of the screw and increased the screw pitch between the screws. When heating, the plastic can be fully plasticized and melted in the barrel; the variable diameter type is adopted, which technically increases the relative service life of the screw. The material improves the performance of the entire PET recycle pelletizing machine.


The barrel of the granulator

The barrel of the PET recycle pelletizing machine is designed with high hardness and certain wear resistance and corrosion resistance after fine processing and quenching treatment, and a certain size slot hole is set at the feeding end to facilitate feeding.


Automatic temperature setting

The heating system of the PET recycle pelletizing machine is composed of heating rings, which are distributed separately outside the barrel to evenly heat and plasticize the materials in the barrel, and through the control of the instrument on the electric cabinet, the change of the set temperature is automatically adjusted. To achieve the stability of the temperature in the barrel of the PET recycle pelletizing machine, a cooling fan is added to the bottom of the barrel in the design. Through the automatic temperature control, it will automatically cool when the temperature is too high, which increases the temperature stability of the barrel.


Process of PET Recycled Granulator

The PET recycle pelletizing machine cleans the aluminum-plastic composite waste, smashes it through a 10-day sieve, and then performs agglomeration. This process can use the agglomerator of Beijing Plastic Machinery Factory. The pellet process condition is water spraying. PET recycle pelletizing machine extrudes the pelletized material with the extruder. If it is not a semi-finished product, add 20% aluminum powder, resist compatibilizer and other additives to this semi-finished product, and then extrude the pellets to obtain the finished product.

PET has a wide range of products, including PET polyester plastic bottles, PET polyester films, PET non-woven fabrics, engineering plastics, and composite multi-functional products. PET products are not easily degraded by air or microorganisms in a short time, causing pollution. The recycling of waste PET materials is of great benefit to environmental protection, resource conservation and sustainable development. The PET recycles pelletizing machine can reduce environmental pollution, and can turn waste into treasure, and obtain huge economic benefits from it.
