Polyester Fiber Recycling Granulator

Product Overview

The polyester fiber recycling granulator is a specialized resource recovery equipment designed specifically for chemical fiber waste filaments and textile yarn scraps. It is a custom-made product with no fixed price, strictly tailored to meet the customer’s production capacity requirements. This equipment efficiently addresses industry challenges such as tangled and bridging issues when feeding fluffy fibers, enabling the resourceful reuse of various types of textile waste. It helps textile mills, chemical fiber plants, and other enterprises reduce waste disposal costs while also decreasing their need to purchase virgin chemical fiber raw materials, delivering both environmental benefits and economic gains. The equipment is compatible with polyester, polypropylene, nylon, and other types of chemical fiber waste filaments and yarns, capable of processing short and long filaments, yarns, and other forms of textile waste. Its standard capacity ranges from 200 to 1500 kg/h, meeting the waste recycling needs of businesses of different scales.

Technical Principle

This equipment employs a core process of “front-end shredding device + pre-compression feeding + single-screw extrusion,” forming a complete fiber recycling granulation workflow. First, long-fiber waste filaments pass through a dedicated cutting device, being chopped into neat short fiber segments to resolve the entanglement issues associated with long fibers during feeding. Next, these short segments enter the pre-compression feeding mechanism, where they are thoroughly compacted before being fed into the barrel, preventing bridging and smooth feeding problems caused by fluffy fibers. Inside the barrel, a high-shear screw design effectively breaks up fiber bundles, working in tandem with a segmented heating system to ensure thorough melting and plasticization, thus guaranteeing uniform particle quality. Meanwhile, the equipment is equipped with a vacuum degassing system that efficiently removes oils, moisture, and volatile substances adhering to the fiber surface, avoiding bubbling or breakage during granulation. Finally, after multi-stage filtration to remove impurities, the molten material is extruded, water-cooled, and cut into pellets, yielding standardized recycled granules.
