Purui Meltblown Fabric Recycling Granulator

Product Overview

The Purui Meltblown Fabric Recycling Granulator is a specialized granulation machine designed specifically for nonwoven fabric recycling. It features a densifier-based pelletizing feed system that effectively addresses the challenge of feeding fluffy nonwoven fabrics. The equipment employs a low-temperature, precision temperature-controlled extrusion process, which maximizes the preservation of the material’s core properties. It is suitable for processing various types of nonwoven fabrics and meltblown fabric waste, including PP and PET, with a standard capacity ranging from 300 to 1500 kg/h and a main motor power of 30–315 kW. This product is manufactured under the PURUI brand, originating in Nantong, and can be custom-made according to customers’ production requirements. It helps nonwoven fabric manufacturers, mask producers, and other related enterprises achieve resource recovery from waste materials, thereby reducing both production and waste disposal costs.

Technical Principle

This equipment utilizes an integrated process combining a densifier and a single-screw extruder. A dedicated treatment procedure has been designed specifically for fluffy nonwoven fabric waste: First, the fluffy nonwoven fabric waste is directly fed into the densifier chamber, where high-speed rotating blades shear and crush the material. Frictional heat generated during this process causes the material to self‑heat and shrink, compacting it into uniform pellets with a bulk density increased by 3–4 times, thus resolving common issues such as bridging and slippage in conventional feeding systems. Second, the compacted pellets are smoothly fed into the extrusion screw, where a low‑temperature, precisely controlled extrusion process maintains optimal processing temperatures, preventing high‑temperature degradation of fibers. Simultaneously, a vacuum degassing system efficiently removes oils and moisture from the material. Finally, after filtration to remove impurities, water‑cooled pelletizing completes the shaping process, ensuring the purity and performance of the finished granules.

Core Value of the Product

1. Resource Recovery from Waste: Helps enterprises achieve 100% in‑plant recycling of nonwoven fabric production scraps, mask waste, and other discarded materials, replacing traditional incineration and landfill disposal methods. This not only reduces resource wastage but also cuts annual waste disposal costs by hundreds of thousands of yuan.
2. Reduction in Raw Material Costs: Recycled granules can be directly reused in the production of lower‑grade nonwovens and injection‑molded products, reducing raw material expenses by approximately 25% compared to virgin materials, significantly lowering production costs.
3. High Capacity and Efficient Output: Supports 24‑hour continuous operation, producing up to 36 tons of recycled granules per day, meeting large‑scale waste processing needs and enhancing enterprise recycling efficiency.
4. Customization: Can be tailored to meet specific customer production requirements, adapting flexibly to different scales of operations and various nonwoven fabric waste scenarios.

Target Customer Base

The target customer base includes nonwoven fabric manufacturers, mask production facilities, geotextile companies, hygiene product factories, and textile waste recycling enterprises. For these businesses, which generate substantial amounts of nonwoven fabric scraps and waste during production, this equipment provides a professional recycling and granulation solution, helping them realize circular economy goals while reducing costs and improving efficiency.

Application Scenarios

The Purui Meltblown Fabric Recycling Granulator is widely used in the recycling and granulation of PP spunbond nonwovens, PET needle‑punched nonwovens, meltblown fabric scraps, geotextile waste, sanitary nonwovens, and mask waste. Whether it’s leftover scraps from nonwoven fabric production, discarded fabric from mask manufacturing, or obsolete materials from geotextiles and sanitary nonwovens, all can be processed using this equipment to produce recyclable granules, enabling the circular use of resources.

Solutions to Industry Pain Points

1. Solving Unstable Feeding Issues: Addressing the problem of unstable feeding caused by the fluffy texture of nonwoven fabrics—where conventional feeding often leads to bridging, slippage, and significant production fluctuations—the densifier‑based pelletizing feed system compacts fluffy materials into high‑density pellets, ensuring uniform and stable feeding and maintaining consistent production output.
2. Improving Poor Performance of Recycled Materials: Conventional high‑temperature processing often results in severe fiber degradation and inadequate recycled material performance. By adopting a low‑temperature, precisely controlled extrusion process, this equipment prevents high‑temperature fiber degradation, achieving a granule performance retention rate of ≥80% and enhancing the usability of recycled materials.
3. Reducing Waste Disposal Costs: Traditionally, production scraps are disposed of through incineration or landfill, resulting in high costs and resource wastage. This equipment enables 100% in‑plant recycling of scrap materials, saving tens of thousands of yuan annually in waste disposal costs while lessening environmental impact.
4. Simplifying the Production Process: Eliminating the need for pre‑crushing steps, the machine allows direct processing of whole bundles of waste, streamlining the production workflow, reducing process steps, and boosting recycling efficiency.
