Purui Textile Waste Yarn Granulator

Product Overview

The Purui textile waste yarn granulator is a specialized resource recovery device designed specifically for chemical fiber waste filaments and textile yarn scraps. It efficiently addresses industry challenges such as the tendency of fluffy fibers to entangle and bridge during feeding, transforming various types of textile waste into usable recycled pellets and enabling the resourceful reuse of textile waste yarns. As a customized product, the equipment can be tailor-made according to customers’ production capacity requirements, with standard capacities ranging from 200 to 1500 kg/h. It is compatible with polyester, polypropylene, nylon, and other chemical fiber waste filaments and yarn scraps, meeting the waste treatment needs of enterprises of different scales. Manufactured under the PURUI brand and originating in NANTONG, the machine features core components sourced from internationally renowned brands, ensuring operational stability and extended service life, thus providing efficient, environmentally friendly waste treatment solutions for textile mills, chemical fiber plants, and similar businesses.

Technical Principle

This granulator employs a complete process flow comprising a “front-end chopping unit + pre-compression feeding + single-screw extrusion,” with a dedicated processing sequence tailored to the characteristics of textile waste: First, long-fiber waste yarns are cut into short segments by the chopping unit, resolving the issue of entanglement when feeding long fibers; second, a pre-compression feeding mechanism compacts the fluffy short segments, preventing bridging during feeding and ensuring stable material delivery into the barrel; third, a high-shear screw structure breaks up fiber bundles, while segmented heating ensures thorough melting and plasticization of the material, guaranteeing uniform pellet formation; fourth, a vacuum degassing system effectively removes oils, moisture, and volatile substances adhering to the fiber surface, avoiding bubbles or broken strands in the finished pellets; finally, after multi-stage filtration to remove impurities, the material is extruded, water-cooled, and pelletized, yielding recycled pellets with low impurity content and compliant moisture levels.
