Purui Nylon Waste Filament Recycling Granulator

Product Overview

The Purui Nylon Waste Filament Recycling Granulator is a specialized granulation machine designed specifically for chemical fiber waste filaments and textile yarn scraps. It is a customized product with no fixed price, tailored according to the customer’s production capacity requirements. This equipment addresses industry challenges such as loose fibers easily tangling and bridging during feeding, enabling the resourceful reuse of textile waste filaments. It helps textile mills, chemical fiber plants, and other enterprises reduce waste disposal costs while decreasing their reliance on purchasing virgin chemical fiber raw materials, delivering both environmental benefits and economic value. The machine is compatible with various types of chemical fiber waste filaments and yarns, including polyester, polypropylene, and nylon, as well as diverse forms of textile waste such as short and long filaments and yarns. Its standard capacity ranges from 200 to 1500 kg/h, meeting the waste processing needs of businesses of different scales.

Technical Principle

The Purui Nylon Waste Filament Recycling Granulator employs a combined process featuring a front-end shredding unit, pre-compression feeding, and single-screw extrusion to achieve efficient granulation 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. Then, a pre-compression feeding mechanism compacts the fluffy short segments, preventing bridging and ensuring stable delivery into the barrel. Equipped with a high-shear screw design, it effectively breaks up fiber bundles, while a segmented heating system ensures thorough melting and plasticization of the fibers, guaranteeing uniform particle quality. Additionally, a vacuum degassing system removes surface oils, moisture, and volatile substances, avoiding bubbling or breakage during granulation. Finally, multi-stage filtration eliminates impurities, followed by water-cooled pelletizing to produce high-quality recycled pellets with impurity content ≤1% and moisture content ≤0.3%.
