PP Regrind
It's common to see them as plastic chairs, toy parts, baskets, trash cans, pipes, bottles, bottle caps, and others because they provide stronger protection for goods.
HDPE Regrind
HDPE regrind is widely used in containers, plastic bottles, pipes, playground equipment, and more due to its high strength, impact resistance, and chemical durability.
PVC Regrind
PVC regrind is widely used in pipes, flooring, cable insulation, and window frames due to its durability, chemical resistance, and adaptability for various applications.
ABS Regrind
ABS regrind is commonly used in automotive parts, electronics housings, toys, and appliances, valued for its toughness, impact resistance, and excellent surface finish.
Rigid Plastic
Producers are exploring solutions for PE pipes, PP containers, ABS automobile components, and more, and the origins of these wastes are diverse across industries.
PET Regrind
PET regrind is extensively used in bottles, food containers, and packaging materials due to its strength, clarity, and excellent barrier properties, making it ideal for preserving freshness.

Frequently Asked Questions
Can this line handle mixed rigid plastics?
Yes. The modular process (granulation → friction wash → sink‑float → dewatering → thermal dryer → air classification) can be tuned per input mix. We adjust screen sizes, tank length, and separation parameters to your feedstock.
What final moisture level can I expect?
With centrifugal dewatering followed by thermal drying, flakes typically reach below 3% moisture, suitable for storage or downstream pelletizing.
Is water consumption high?
No. The system supports closed‑loop water reuse. Proper filtration and settling reduce make‑up water and operating cost.
How do you size the configuration?
We size motors, tank length, and dryer power based on throughput targets, contamination level, and available floor space. Share your material samples for a tailored proposal.
What is the typical lead time?
Standard lines ship in 6–10 weeks depending on customization and current production schedule.
