Process of PP PE Bottle Washing Line
A pp pe bottle washing line processes waste plastic through sorting,shredding,and intensive washing to produce clean,high-purity flakes.The process typically involves conveyor feeding,de-labeling,wet crushing,sink-float separation,friction washing,hot washing to remove adhesives,rinsing,and finally,drying to achieve high-quality,reusable material.
Its key stages include as follows:
1. Pre-treatment (Sorting & Label Removal):
Sorting:Automatic sorting removes contaminants like non-plastic materials (metals,glass) and other plastic types.
De-labeling:A specialized label removal machine separates labels,often via mechanical stripping.
2. Size Reduction (Shredding/Crushing):
Wet Grinding: The bottles are crushed into uniform flakes (10-15mm) using a plastic recycling granulator machine.Water is added during this process to initiate cleaning and reduce knife wear.
3. Washing and Cleaning:
Friction Washing:High-speed friction washer removes contaminants like sand,glue,and residue from the surfaces of the flakes.
Hot Washing:To remove persistent adhesive and oils,the flakes undergo hot washing using detergent.
4. Separation:
Sink-Float Tank:Uses density differences to separate contaminants.Because PE/PP plastics are lighter than water,they float,while heavier impurities (metal,stones) sink to the bottom.
5. Rinsing and Drying:
Rinsing:Cleaned flakes are rinsed to remove remaining chemicals and detergents.
Drying:Centrifugal dewatering and hot air drying reduce the moisture content to below 2%(Rigid Materials) or 3% - 5%(Soft Materials) for high-quality,reusable pellets.
