FAQ
A: PET bottle crushing and washing line is used to recycle post-consumer PET bottles into clean PET flakes. The system removes labels, caps (PP/PE), glue residues, dirt, and metal contaminants. The final PET flakes can be used for polyester fiber production, rPET pelletizing, or PET sheet extrusion.
A: The capacity depends on configuration and customer requirements. A common industrial configuration operates at 1000kg/h. Larger customized systems can achieve higher outputs depending on plant layout, washing stages, and drying requirements.
A: The separation process uses density-based flotation technology. In the floating washing tank, PET flakes sink while PP/PE caps and label fragments float. This method ensures efficient impurity removal and high-purity PET flake output.
A: The crusher determines flake size uniformity and overall line stability. An upgraded crusher with dual spiral force-feeding prevents material bridging, improves crushing efficiency, and maintains stable throughput when processing lightweight PET bottles.
A: High-quality PET washing lines produce flakes with:
High purity
Low moisture content
High label removal rate
Minimal contamination
Such flakes can meet fiber-grade recycling standards and are suitable for polyester fiber manufacturing and high-value rPET applications.
