PP/PE Regrind Washing & Pelletizing Line
Convert contaminated PP/PE film and regrind into high‑quality pellets with a clean, energy‑efficient process designed for consistent output and low moisture.
Why Choose This Line
Clean pellets, stable throughput, and flexible configurations that fit your materials and scale.
High Purity Output
Meticulous washing and separation deliver clean pellets suitable for demanding applications.
Energy Efficient
Optimized modules and smart layout reduce energy consumption and OPEX.
Modular & Customizable
Configure to match contamination levels, space constraints, and target capacity.
Key Line Components
A high-performance line built with precision-engineered modules for maximum uptime and superior flake quality.
Plastic Shredder Machine
Single-shaft shredder pre-cuts film to prevent tangling and blockages.
Plastic Granulator (Wet Grinding)
Size reduction to ~10–20 mm with water flushing for pre‑wash.
Friction Washer
High‑speed scrubbing (≈1000 RPM) removes embedded dirt, labels, and paper fibers.
Sink/Float Separation Tank
Water‑based density separation to discharge stones, metals, and grit.
Centrifugal Dewatering
Spins off surface water to cut energy use before thermal drying.
Screw Press Dewatering (Optional)
High‑pressure squeezing can replace both centrifugal and thermal stages in some setups.
Thermal Dryer & Cyclone
Hot‑air tube drying and cyclone cooling remove residual moisture and fines.
Product Silo
Clean, dry flakes buffer for stable pelletizer feeding.
Plastic Pelletizing Machine
Water‑ring pelletizer melts, filters, and cuts to uniform, high‑quality pellets.
Process Flow
A high-efficiency, multi-stage system designed to transform contaminated PP/PE waste into clean, high-quality regrind and pellets.
Shredded PP/PE film and regrind prepared to stable, conveyable sizes.
Friction cleaning rapidly removes labels, paper, and surface contaminants.
Density separation ejects heavy impurities while retaining PP/PE film.
Centrifugal dewatering or squeezer + hot air pipes achieve ≤ 3–5% moisture.
Water‑ring system melts, filters, and cuts into round pellets ready for reuse.
Typical Layout
A compact, modular arrangement suitable for 300–2000 kg/h lines with upgrade paths.
Applications
Flexible Packaging
Post-consumer LDPE/LLDPE stretch film, shrink wrap, and commercial packaging waste.
Agricultural Film
Heavily soiled mulch film, greenhouse film, and irrigation tubing (requires pre-shredding and stone removal).
Woven & Jumbo Bags
PP raffia, FIBCs (jumbo bags), woven cement/fertilizer bags with high tensile strength.
Rigid PP/PE Regrind
Defective injection/blow molded parts, pipes, bottles, and crates crushed into regrind flakes.
Post-Industrial Scrap
Clean or lightly printed production offcuts, edge trims, and defective rolls from film manufacturing.
Frequently Asked Questions
Find quick answers to technical specifications, compliance, and service details for our washing lines.
What capacities are available?
Standard configurations cover 300–2000 kg/h. We tailor line modules to your material mix, contamination, and staffing to achieve stable throughput.
Power and compliance for EU/US?
EU setups typically use 400V/50Hz, US 460V/60Hz (others on request). Machines meet CE requirements; UL-listed components and English HMI are available.
Water usage and recycling?
Closed-loop water systems with filtration minimize consumption and discharge. We can integrate DAF and sludge handling to fit local regulations.
Installation, commissioning, and training?
We provide layout drawings, remote/onsite commissioning, and operator training. Typical installation takes 2–4 weeks depending on line size.
Lead time and shipping?
Lead time is usually 6–12 weeks ex‑works depending on configuration. We support FOB/CIF and arrange crating suitable for sea freight.
