High-Speed Friction Washer: Core Technology for Efficient Plastic Recycling
2026-04-13
In modern plastic recycling systems, achieving high-purity output is essential for downstream processing and product value. Among all washing equipment, the
High-Speed Friction Washer plays a critical role in removing stubborn contaminants from plastic flakes.
It is widely used in PET bottle recycling lines, PP/PE film washing systems, and rigid plastic reprocessing applications.
Product Overview
The High-Speed Friction Washer is a cold washing machine designed to clean plastic flakes using high-speed mechanical friction combined with controlled water spraying.
Its main function is to remove:
- Labels
- Oil stains
- Dirt and sand
- Organic residues
By applying strong friction between materials and machine components, contaminants are effectively separated.
Working Principle
The machine operates based on high-speed rotational friction and centrifugal cleaning.
- Feeding Stage：Plastic flakes enter from the lower inlet of the inclined machine body.
- High-Speed Friction：A rotor shaft with multiple paddles rotates at speeds up to 1000–1400 RPM, generating strong friction between particles.
- Spray Rinsing：Water jets continuously spray onto the mesh screen to flush away contaminants.
- Discharge：Clean materials are discharged from the upper outlet and move to drying equipment.
Key Features
- High Cleaning Efficiency：Removes stubborn impurities through strong mechanical scrubbing.
- Low Waterj- Consumption：Optimized spray system reduces water usage compared to traditional washing systems.
- Continuous Operation：Designed for stable, uninterrupted production.
- Durable Structure：Made of stainless steel and wear-resistant components for long service life.
Applications
The High-Speed Friction Washer is suitable for:
- PET bottle flakes cleaning
- PP/PE film washing
- Rigid plastics (HDPE, ABS, PS)
- Recycling production lines
It is typically installed after hot washing or crushing and before drying.
