PP Regrind
Suitable for chairs, baskets, bottles, caps, and rigid packaging waste requiring washing and moisture reduction.
HDPE Regrind
Common in containers, bottles, pipes, and industrial scrap where strong washing performance is required.
PVC Regrind
Applicable to pipes, profiles, cable insulation, and construction scrap with washing and sorting needs.
ABS Regrind
Used for automotive parts, electronic housings, and appliance scrap that needs cleaning before reuse.
Mixed Rigid Plastic
Suitable for diverse rigid plastic streams from packaging, consumer goods, automotive, and industrial sources.
PET Regrind
Can be processed in applications requiring removal of dirt, labels, caps, and residual moisture before reuse.
Process
Feed & Meter
Load materials and maintain stable feeding for the full washing line.
Wet Granulation
Cut rigid plastics into smaller pieces while beginning surface cleaning.
Friction Wash
High-speed friction removes dirt, paper, sand, and loose contamination.
Sink-Float
Separate lighter PP and PE fractions from heavier contaminants or other plastics.
Hot Wash
Deep cleaning stage for oils, glue, and stubborn residues.
Dewater
Centrifugal dewatering lowers moisture before the final drying stage.
Thermal Dry
Hot-air drying reduces moisture to below 3 percent for storage or pelletizing.
Air Classify
Remove light labels and fines for cleaner final flakes.
Our Technology Advantage
Eco-Friendly
Optimized water and energy usage support more sustainable rigid plastic recycling.
High Output Quality
Integrated washing and drying stages help improve flake cleanliness and consistency.
Engineered Reliability
Robust equipment selection and industrial-grade materials support long-term uptime.
Modular & Scalable
The line can be expanded or adjusted according to capacity, contamination, and final use requirements.
Main Equipment
A typical rigid plastic washing line may include the following modules depending on material type and output requirements.
Screw Feeder
Durable continuous conveying for flakes and regrinds, helping stabilize line flow and reduce pooling between stages.
Specifications
- Conveys materials between stages
- Helps filter water carryover
- Supports surface sediment removal

Wet Plastic Granulator
Performs size reduction and pre-cleaning for bottles, rigid plastics, and contaminated scrap before the washing stages.
Specifications
- Cuts plastic materials efficiently
- Loosens dirt and contamination
- Helps reduce dust and wear
Friction Washer
High-speed friction cleaning and conveying module for rigid flakes, labels, and fine contamination removal.
Specifications
- Intensive surface cleaning
- Continuous transfer between modules
- Removes soil, labels, fines, and sand

Floating Separation Tank
Water-based sink-float separation splits light and heavy fractions while continuing the washing process.
Specifications
- W-shaped bottom improves separation efficiency
- Dual-section design helps contaminant control
- Cleans and separates simultaneously
Hot Washer
Continuous hot chemical washing improves removal of oils, glue, and stubborn contaminants on rigid plastic flakes.
Specifications
- Single-pass cleaning for many applications
- High removal rate of sticky contaminants
- Can pair with cold wash sequences as needed
Centrifugal Dryer
Initial dewatering stage that uses centrifugal force to lower moisture before thermal drying.
Specifications
- High dewatering efficiency
- Handles elevated water content
- Compatible with water recycling systems
Thermal Dryer
Hot-air dehydration stage used to bring final moisture below 3 percent and improve storage or pelletizing readiness.
Specifications
- Continuous drying process
- Integrated cyclone separator
- Efficient dust and fines removal
Zig-Zag Air Classifier
Air-based sorting stage for removing light contaminants such as labels, paper, and residual fines.
Specifications
- High-efficiency lightweight separation
- Supports partial drying
- Dual-exit design for clean split

Frequently Asked Questions
Yes. The line can be configured for mixed rigid plastic feedstock including PP, HDPE, PVC, ABS, and other regrinds. Sizing depends on contamination level, density separation needs, and required output quality.
With centrifugal dewatering followed by thermal drying, final moisture is typically below 3 percent, suitable for storage or downstream pelletizing.
No. The system supports closed-loop water reuse with filtration and settling, which helps reduce make-up water demand and operating cost.
We size the line based on material type, contamination level, throughput target, and available floor space. Sample evaluation can be used to confirm the most suitable layout.
