Request a Custom QuoteSelection Criteria
Primary factors that determine module selection, utilities sizing, and output consistency for rigid regrind.
Moisture Target
Discharge moisture is set by the dewatering + thermal drying configuration. We size the drying stage to match your specific extrusion requirements.
Decontamination
Cleaning intensity is selected based on label load, oil/adhesive contamination, and fines content (cold vs. hot wash options).
Material Mix
Sink-float separation and optional air classification are selected based on PP/PE mixes, PVC risk, and light contaminants.
Water Loop
Open or closed-loop water design impacts filtration requirements, wastewater handling, and operating cost based on your site constraints.
Maintenance
Wear protection and maintenance intervals are driven by abrasive fines and label glue across granulation and friction washing.
Footprint
Conveyor routing and machine placement are configured to match your available space and material handling plan.
Supported Materials
Engineered to process a wide range of rigid plastics into high-purity feedstock.
PP regrind
Crates, caps, household items, and industrial housings. Optimized label and oil removal.
HDPE regrind
Bottles, drums, pipes, and crates. High-efficiency residue cleaning.
PVC regrind
Durable pipes, flooring, and window frames. Robust size reduction and separation.
Process Architecture
A proven multi-stage workflow from infeed to thermal drying.
Core Equipment Modules
Wet Plastic Crusher
Optimized for rigid regrind, providing consistent flake sizing and initial contaminant release.
- D2 high‑carbon, high‑chromium steel blades
- V‑shape or double‑scissor cutting arrangement
- Water-inlet for simultaneous cutting and rinsing
Friction Washer
High-speed mechanical scrubbing to effectively remove label glue, stubborn oils, and paper fines.
- Rotor Speed: 500–600 RPM for intense friction
- Continuous water flow to flush debris
- Replaceable high-wear components for durability
Sink-Float Tank
Precision density separation to isolate PP/PE from heavier contaminants like PVC or metals.
- All-304 stainless steel interior construction
- Adjustable paddle speed for residence time control
- Multi-section design for advanced rinsing
