Purui Nonwoven Fabric Edge Scrap Granulator

Product Overview

The Purui brand’s nonwoven fabric edge scrap granulator is a specialized recycling and granulation machine for nonwoven fabrics, originating from Nantong. It is specifically designed to address the challenge of feeding fluffy nonwoven materials, featuring a compacting and agglomeration feeding system. Utilizing a low-temperature, precisely controlled extrusion process, it effectively preserves the core properties of the material. The equipment supports customization with no fixed price; it is tailored according to the customer’s production volume requirements. It can directly process entire bales of nonwoven fabric edge scraps, eliminating the need for pre-crushing steps. Suitable for recycling and granulating various materials such as PP spunbond nonwovens, PET needle-punched nonwovens, meltblown fabric scraps, geotextile waste, sanitary nonwovens, and mask waste, this machine helps nonwoven fabric manufacturers, mask processing plants, and other enterprises achieve 100% in-house reuse of production edge scraps, significantly reducing waste disposal and raw material costs.

Technical Principle

This granulator employs an integrated compacting and single-screw extrusion process, with a complete treatment workflow designed specifically for fluffy nonwoven waste. First, the fluffy nonwoven scraps are fed directly into the compactor chamber, where high-speed rotating blades shear and crush the material. Friction within the chamber generates heat, causing the material to self‑heat and shrink into uniform agglomerates, increasing its bulk density by 3–4 times. These agglomerates are then smoothly fed into the extrusion screw, fundamentally solving the bridging and slipping issues common in conventional feeding equipment. During the extrusion phase, the machine uses a low‑temperature, precisely controlled extrusion process to prevent fiber degradation caused by excessive heat. Paired with a vacuum degassing system, it efficiently removes oils and moisture from the material. After filtration to remove impurities, water‑cooled pelletizing completes the shaping process, ensuring that the finished pellets retain ≥80% of their original performance while maintaining impurity levels ≤1%.

4. High capacity and efficient recycling: Operating continuously for 24 hours, it can produce up to 36 tons of recycled pellets per day, rapidly handling daily nonwoven edge scrap generation and enabling 100% in‑house reuse of production scraps, thus avoiding resource waste and high disposal costs associated with incineration and landfilling.
5. Customizable solutions: Tailored to meet specific customer production needs, it flexibly matches different enterprise scales and processing requirements, providing more practical recycling and granulation solutions.

Core Value of the Product

1. Resource circularity: Transforming nonwoven edge scraps—previously destined for incineration or landfill—into reusable recycled pellets, achieving 100% in‑house resource reuse, reducing waste, and promoting green manufacturing principles.
2. Significant cost reduction: Helping enterprises save hundreds of thousands of yuan annually on waste disposal costs, while recycled materials can substitute part of new raw materials, cutting raw material expenses by 25% and effectively lowering overall production costs.
3. Ensuring recycled material quality: The low‑temperature process prevents fiber degradation, maintaining ≥80% of pellet performance and keeping impurity levels ≤1%, guaranteeing that recycled materials can be directly used in production without additional processing, meeting the raw material requirements of low‑end nonwovens and injection‑molded products.
4. Simplified production process: Eliminating the need for pre‑crushing steps, allowing direct processing of whole bales of waste, reducing production stages, improving recycling efficiency, and decreasing labor input.

Target Customer Groups

Nonwoven fabric manufacturers, mask processing plants, geotextile companies, sanitary material producers, textile waste recycling enterprises, and other businesses generating various types of nonwoven edge scraps—especially those with large-scale waste recycling needs, seeking to reduce production costs, and aiming for resource circularity—can all meet their recycling and processing demands through this customized granulator.

Application Scenarios

This granulator is primarily used for recycling and granulating various types of nonwoven fabric waste, including mask waste generated during mask production, PP spunbond nonwoven edge scraps from nonwoven fabric factories, PET needle‑punched nonwoven waste, meltblown fabric edge scraps, geotextile waste from geotextile companies, and sanitary nonwoven waste from sanitary material manufacturers. It transforms these fluffy, difficult-to-handle wastes into stable, high‑performance recycled pellets, which can then be reused in low‑end nonwoven fabric production, injection‑molded product manufacturing, and other applications, realizing resource circularity.
