Industrial Fiber Waste Granulator

Product Overview

The industrial fiber waste granulator is a specialized resource‑recycling device designed for chemical fiber waste filaments and textile yarn scraps. Developed specifically to address the challenge of feeding fluffy fibers, it enables efficient recovery and circular reuse of textile waste. The equipment supports customized production with no fixed price; it is tailor‑made according to the customer’s output requirements. It accommodates various types of chemical fiber waste filaments and yarns, such as polyester, polypropylene, and nylon, as well as different forms of textile waste including short and long filaments and yarns. Standard capacity ranges from 200 to 1,500 kg/h, meeting the waste‑processing needs of enterprises of varying scales. The product brand is PURUI, originating from NANTONG. Core components are sourced from internationally renowned brands, ensuring stable operation and extended service life, providing an efficient waste‑resource‑recycling solution for textile mills, chemical fiber plants, and other related businesses.

Technical Principle

This granulator employs a combined process of a front‑mounted shredding unit, pre‑compression feeding, and single‑screw extrusion, featuring a complete processing flow tailored to the characteristics of fiber waste. First, long filament waste is cut into short segments by the shredding device, resolving the issue of long fibers easily tangling during feeding. Next, a pre‑compression feeding mechanism compacts the fluffy short segments, preventing bridging and ensuring steady material delivery. Subsequently, the fiber material fed into the barrel is dispersed by a high‑shear screw structure, while staged heating ensures thorough melting and plasticization, guaranteeing uniform fiber fusion. An integrated vacuum venting system effectively removes oils, moisture, and volatiles adhering to the fiber surface, avoiding bubbles or broken strands during granulation. Finally, after multi‑stage filtration to remove impurities, the material is extruded through either die‑face cutting or strand‑cutting processes, followed by water‑cooling and pelletizing, yielding high‑quality recycled pellets with impurity content ≤1% and moisture content ≤0.3%.
