Spunbond Nonwoven Recycling Pelletizer

Product Overview

This is a nonwoven-specific pelletizing machine manufactured by the PURUI brand and originating from NANTONG. It is specially designed to address the challenge of feeding fluffy nonwoven materials, featuring a densifier–pelletizing feed system that can directly process whole bales of nonwoven scraps, eliminating the need for pre‑crushing. The equipment employs a low‑temperature, precision temperature‑controlled extrusion process, effectively preventing high‑temperature degradation of fibers. The finished pellets maintain a performance retention rate of ≥80% and have an impurity content of ≤1%. It can convert various textile waste materials—including PP spunbond nonwovens, PET needle‑punched nonwovens, and meltblown fabric scraps—into reusable recycled pellets, helping enterprises achieve 100% in‑plant reuse of production scraps and significantly reducing raw material and waste disposal costs.

Technical Principle

The equipment integrates a densifier with a single‑screw extrusion process, featuring a dedicated treatment workflow tailored to the characteristics of fluffy nonwoven waste. First, the fluffy nonwoven scraps are fed directly into the densifier chamber, where high‑speed rotating and stationary blades shear and crush the material. During rapid friction, the material self‑heats, contracts, and compacts into uniform pellets, increasing its bulk density by 3–4 times before being smoothly fed into the extrusion screw. This fundamentally solves the bridging and slippage issues common in conventional feeders, ensuring uniform and stable feeding. Subsequently, a low‑temperature, precision temperature‑controlled extrusion process is employed, strictly regulating processing temperatures to prevent high‑temperature fiber degradation. A vacuum degassing system removes oils and moisture from the material, followed by filtration to eliminate impurities. Finally, water‑cooled pelletizing or strand‑cutting processes produce the finished pellets, resulting in high‑performance recycled granules.
