Purui Nonwoven Fabric Recycling Granulator

Product Overview

The PP nonwoven fabric recycling granulator is a specialized granulation device designed specifically for recycling nonwoven waste. It features an innovative compacting and agglomeration feeding system that thoroughly resolves the industry’s longstanding challenges of bridging and slippage when processing fluffy nonwoven materials. The equipment employs a low-temperature, precision temperature-controlled extrusion process, effectively preventing high-temperature degradation of fibers and maximizing the preservation of the raw material’s core properties. The finished pellets maintain a performance retention rate of ≥80%, with impurity content ≤1%. The machine can directly process entire bales of nonwoven edge trimmings, eliminating the need for pre-crushing steps. Its standard capacity ranges from 300 to 1500 kg/h, making it suitable for recycling and reusing various types of PP and PET nonwovens as well as meltblown fabric waste, helping enterprises achieve 100% in-house reuse of production scraps and significantly reducing both waste disposal and raw material procurement costs.

Technical Principle

This granulator utilizes an integrated compacting unit combined with a single-screw extrusion process to efficiently recycle fluffy nonwoven waste. First, fluffy nonwoven scraps are fed directly into the compactor chamber, where high-speed rotating and stationary blades shear and crush the material. Frictional heat generated during this rapid process causes the material to self‑heat and contract, forming uniform agglomerates with a bulk density increased by 3–4 times. These compacted agglomerates are then smoothly fed into the extrusion screw, fundamentally addressing issues of bridging and slippage associated with fluffy feedstock. Subsequently, the material enters a low-temperature, precisely controlled extrusion stage, where processing temperatures are strictly managed to prevent high‑temperature fiber degradation. A vacuum venting system efficiently removes oils and moisture, followed by filtration to eliminate impurities. Finally, water‑cooled pelletizing produces recycled pellets with low impurity levels and high retained performance.

Target Customer Groups

Nonwoven fabric manufacturers, mask production facilities, geotextile companies, sanitary product factories, and textile waste recycling enterprises—any production entity generating PP or PET nonwoven and meltblown fabric scraps—can utilize this equipment to achieve efficient recycling and reuse of their waste.

Application Scenarios

This equipment is widely applicable to various nonwoven waste recycling and granulation scenarios, including PP spunbond nonwoven scraps, PET needle‑punched nonwoven waste, meltblown fabric scraps, geotextile waste, sanitary nonwoven scraps, and mask fabric waste. The resulting recycled pellets can be directly reused in the production of lower‑grade nonwovens, injection‑molded products, and other applications, realizing resource circularity and helping enterprises build closed-loop production systems.

Solving Industry Pain Points

1. Addressing the challenge of feeding fluffy nonwovens: For nonwoven fabrics that are inherently fluffy and prone to bridging and slippage with conventional feeding equipment, leading to unstable production capacity, the compactor’s agglomeration feeding system compresses fluffy materials into high‑density pellets, ensuring smooth, uniform feeding and stable output.
2. Improving poor quality of recycled materials: Conventional high‑temperature processing often results in severe fiber degradation, rendering recycled materials unable to meet production requirements. This equipment adopts a low‑temperature, precision temperature‑controlled process, maximizing the preservation of core material properties, achieving a finished pellet performance retention rate of ≥80%, and enabling direct reuse in production.
3. Reducing waste disposal costs: Traditionally, nonwoven production scraps are disposed of through incineration or landfilling, which not only incurs high disposal expenses but also leads to resource waste and environmental pollution. This equipment enables 100% recycling and reuse of scrap materials, saving tens of thousands of yuan annually in waste disposal costs while simultaneously reducing resource consumption.
