Product Description
The application of PET plastic is extensive, including electronics and electrical appliances, polyester fiber (polyester fabric), PET film, PET beverage bottles (mineral water, cola bottles), PET chemical fiber yarn (textiles, fillers), etc. During processing and usage, a significant amount of scraps and waste materials are generated. Beverage bottles, being single-use items, require recycling after disposal. However, different types of PET materials necessitate distinct recycling processes, techniques, and equipment. Below are several plastic pelletizing machine models designed by our company specifically for recycling various PET plastics.
PET bottles are primarily used for beverage containers such as mineral water and cola. After use, these bottles undergo processes including crushing, cleaning, and separation (removing bottle caps, labels, and isolating the PET bottle body) to produce PET flakes. These flakes are then processed through PET recycling pelletizing equipment to yield PET pellets.
The pelletizing process flow for PET flakes:
PET flakes → Belt feeder → Twin-screw extruder → Hydraulic screen changer → Strand die → Water cooling → Pellet cutting → Dewatering → Vibrating sieve → conveying silo.
