Process
Parameters
Machine Details
Application
1
Feeding & Conveying
Waste PP/HDPE materials are loaded and transported to the shredder automatically.
2
Shredding
A Double Shaft Shredder cuts bulky plastics into smaller, manageable pieces.
3
Crushing
A Crusher grinds shredded pieces into uniform flakes suitable for washing.
4
Friction Washing
High-speed friction cleaning removes surface dirt, oil, and labels.

5
Hot Washing
Heated water and detergent clean off stubborn oil and glue residues.
6
Floating Washing Tank
Separates floating PP/HDPE flakes from heavier impurities by density.
7
Drying System
Removes moisture from flakes using centrifugal or horizontal dryers.

8
Label Separator
Air separation eliminates light label or film residues for higher purity.

9
Storage & Collection
Clean, dry flakes are collected in silos or bags for reuse or pelletizing.

10
Final Output
Produces high-quality recycled PP/HDPE flakes ready for pelletizing or molding.

Machine Details

Belt Conveyor

Feeds rigid plastic waste such as HDPE bottles, PP buckets, or drums evenly into the shredder or crusher. Ensures stable and continuous operation throughout the recycling line.

Crusher

Further crushes pre-shredded materials into uniform flakes. Equipped with high-strength SKD11 blades and water-assisted cutting to prevent heat buildup and deformation.

Friction Washer

High-speed washer that removes sand, dirt, labels, and oil residues through mechanical scrubbing and water spray. Improves flake cleanliness before sink-float separation.

Washing Tank

Separates materials by density — clean HDPE/PP flakes float while heavy contaminants sink. Ensures the removal of paper, metal, and other impurities.

Vertical Dewater

Centrifugal system that removes surface water from washed flakes.
Reduces moisture to below 5% and prevents material loss during drying.

Silo

Centrifugal system that removes surface water from washed flakes.
Reduces moisture to below 5% and prevents material loss during drying.

Drying System

The Drying System is designed to remove residual moisture from washed plastic flakes such as HDPE, PP, or LDPE films after dewatering.

Screw Loader

The squeezer machine combines mechanical squeezing and heat friction to further dewater and densify the washed film flakes.
