Nonwoven Fabric Scrap Regrinding Granulator

Product Overview

This is a specialized granulation machine designed specifically for recycling nonwoven fabric waste. It features a densifier–pelletizing feed system that effectively addresses industry challenges such as bridging and slippage when feeding fluffy nonwoven materials. The equipment employs a low-temperature, precision temperature-controlled extrusion process, which maximizes the preservation of the core properties of nonwoven fabrics. It is suitable for processing PP, PET, and other types of nonwoven and meltblown fabric scraps, with a standard capacity ranging from 300 to 1500 kg/h. It can directly handle entire bundles of nonwoven fabric offcuts, eliminating the need for pre‑crushing steps, thereby helping nonwoven fabric manufacturers achieve efficient recycling and reuse of scrap materials, reducing both waste disposal costs and raw material procurement expenses.

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, fluffy nonwoven scraps are fed directly into the densifier chamber, where high-speed rotating blades shear and crush the material. Frictional heat generated during this process causes the material to self‑heat and contract, compacting it into uniform pellets with a bulk density 3–4 times higher, thus ensuring stable feeding. Second, these compacted pellets are smoothly fed into the extrusion screw, where a low‑temperature, precisely controlled extrusion process maintains optimal processing temperatures, preventing thermal degradation of the fibers. Third, a vacuum degassing system efficiently removes oils and moisture, guaranteeing the purity of the final granules. Finally, after passing through a filtration step to remove impurities, water‑cooled pelletizing completes the shaping process, yielding stable, high‑quality recycled granules.
