Introducing Our Friction Screw Washer – A Smart Solution for Thorough Cleaning and Seamless Conveyance of Plastic Flakes, Films, and Regrind Materials.
At the core of our Friction Screw Washer lies an advanced rotor, featuring angled paddles. Operating at a robust speed range of 500 to 600 RPM, this rotor generates significant frictional force, prompting plastic materials to undergo rigorous scrubbing against each other.
This intense action effectively dislodges and eliminates soil, sand, and various contaminants, ensuring the plastic emerges impeccably clean and ready for further processing.
The cornerstone of our machine’s exceptional cleaning prowess is its innovative use of friction as the primary cleaning mechanism. By facilitating dynamic rubbing between plastic materials, it achieves a level of cleanliness that redefines standards within the recycling industry.
Crafted with a keen focus on both economic and environmental sustainability, the Friction Screw Washer underscores our dedication to advancing a cleaner, greener, and more efficient recycling ecosystem.

Frequently Asked Questions
What materials can the friction screw washer clean?
The washer handles plastic flakes, films, and regrind materials — from PET bottle flakes to flexible films and granulated rigid plastics. Its angled-paddle rotor scrubs all of them through mutual friction, making it a versatile cleaning stage for mixed recycling lines. Because it cleans and conveys in one unit, it slots easily into both PET bottle washing lines and film washing systems.
How does friction washing actually clean the plastic?
An advanced rotor with angled paddles spins at 500–600 RPM, throwing material into vigorous rubbing contact — plastic scrubbing against plastic. This mechanical friction dislodges soil, sand, and surface contaminants far more effectively than soaking alone. The continuous tumbling also keeps material moving through the machine, so cleaning and conveying happen simultaneously without a separate transport stage.
What contaminants does it remove?
Friction washing excels at removing soil, sand, grit, and loose surface dirt from flakes, films, and regrind. For the best flake purity, it is typically paired with upstream label removal and downstream sink/float separation or hot washing for glue and oils. Together, these stages deliver the contaminant-free material buyers expect — see our guide to proven PET flakes washing and drying methods.
Where does the friction screw washer fit in a washing line?
It usually sits after the granulator or shredder, receiving freshly cut flakes or film pieces for intensive scrubbing before sink/float tanks or drying stages. Because the screw action also conveys material forward, it replaces a separate conveyor between washing stages, simplifying line layout. Its compact footprint makes it easy to retrofit into existing lines that need a cleaning-performance boost.
What maintenance does the friction washer require?
The main wear items are the rotor’s angled paddles and the screen or trough surfaces, which see constant abrasive contact — especially with sandy or gritty feed. Inspect them regularly for wear, check the drive and bearings, and keep water spray nozzles clear for consistent cleaning. A preventive schedule matched to operating hours and feed contamination keeps cleaning performance at its peak.
What power and installation does the washer need?
The rotor drive must sustain 500–600 RPM under load, so a stable three-phase supply with proper motor protection is required. The machine needs process water supply and drainage for the washing action, plus a level foundation. Infeed and discharge connect to standard screw or belt conveyors, and the centralized line controls can integrate its start/stop and speed settings for fully automatic operation.
