PET flake pelletizing line

01 — Project introduction

PET drinking bottles are easy to sort and can be economically recycled. PET sorting blue, green, and clear water bottles according to color enables them to be recycled separately.

Through washing, remelting and converting PET waste can easily be recycled and used for brand new PET products. Recycled PET plastic can be used as raw material for manufacturing various high-quality products.

02 — Applicable materials

Raw materials: Beverage bottles, mineral water bottle, food bottles/jars(salad dressing, peanut butter, honey, etc.) after pre-treatment.

03 — Processing Flow

Storing and loading→ volumetric feeding→ twin screw compounding→ melt filter→ die head→ cooling channel→ underwater strand pelletizer→ dewater→ classifier→ conveying and storing
