Cold-Water Washing System
High-Speed Friction Washer for Plastic Recycling
Deliver ultra-clean PET flakes, HDPE/PP regrind, and LDPE film by leveraging 1,000+ RPM friction and targeted rinsing that removes paper, dirt, and organics without flooding your line.
Eliminate Contamination Bottlenecks
The high-speed friction washer is a cold-wash workhorse that unlocks higher resale values by polishing your plastic stream before dewatering, drying, or extrusion.
Remove Stubborn Residues
Strip labels, cardboard fibers, and soil from flakes by forcing material against a stainless mesh at extreme rotational speed.
Cut Water Consumption
Strategically positioned jets rinse contaminants exactly where needed, lowering overall water demand and simplifying recirculation.
Stabilize Throughput
Steep machine geometry keeps material in the wash cavity longer, improving dwell time and enabling consistent downstream feed.
How the Friction Washer Works
A precisely engineered rotor, water injection pattern, and screening shell combine to deliver the cleanest output in the industry.
Inclined Feed
Material enters from the lower end, and the inclined design extends residence time so contaminants can loosen before discharge.
High-Energy Friction
Tilted paddles mounted on a 400–750 mm shaft rotate at 1,080–1,400 RPM, scrubbing plastic against the screen for maximum shear.
Targeted Rinsing
Adjustable spray bars inject clean water at critical points, flushing paper, organics, and sludge through the screen without flooding the drum.
Clean Discharge
Finished flakes exit at the upper end, ready for centrifugal dewatering, thermal drying, or direct feeding into pelletizing systems.
Performance Advantages of a High-Speed Friction Washer
Built for continuous duty in demanding recycling environments while keeping maintenance simple.
Superior Cleaning Efficiency
Achieve premium-grade PET flakes and clean HDPE/PP/LDPE outputs by eliminating dirt, labels, and organics from recycled plastics.
Water-Smart Operation
Use significantly less water than drum-style washers while improving rinse effectiveness and reducing wastewater volumes.
Durable Construction
Heavy-duty housings, replaceable wear liners, and reinforced mesh screens minimize downtime and extend service life.
Scalable Configurations
Select the power and capacity that align with your line—from 400 kg/h pilot setups to 2,000 kg/h high-volume plants.
Applications: PET, HDPE/PP Rigid, LDPE Film
Slot the friction washer between granulators, float-sink tanks, and dryers to build a fully optimized washing circuit.
PET Bottle Flake Lines
Polish rPET flakes after sink-float separation so caps, labels, and organics are removed before dewatering. See our Sink-Float Tank for density separation.
Rigid Plastic Regrind
Clean HDPE crates, PP buckets, and ABS/PS regrind to raise resale value and protect pelletizing equipment.
Film & Sheet Recycling
Remove soil and printing residues from LDPE/LLDPE film flakes while keeping moisture levels low for dryer efficiency.

Frequently Asked Questions
How does the high-speed friction washer enhance cleanliness?
The rotating paddles generate intense shear against a perforated screen, while spray nozzles rinse away loosened contaminants. The combination removes labels, fibers, soil, and light organics that escape standard float-sink separation.
What materials can it process?
The washer handles PET flakes, HDPE/PP regrind, LDPE film flakes, and other shredded plastics that benefit from cold-water friction cleaning before drying or pelletizing.
How much water does the system need?
Unlike drum washers that flood the cavity, this design uses precision jets and nozzles. You get effective rinsing with lower flow rates, making it easier to filter and recirculate process water.
Can the washer be customized for my line?
Yes. We tailor rotor length, spray layout, motor sizing, and stainless upgrades to match your contamination levels and throughput goals. CE-certified builds are available for regulated markets.
Do you provide installation and support?
Each machine includes a 1-year limited warranty. Our engineers can travel on-site for commissioning, and we offer ongoing maintenance training and spare parts programs.
