Waste Woven Bag Regeneration Pelletizing Machine

Product Overview

This waste woven bag regeneration pelletizing machine, manufactured by the PURUI brand, is a wear-resistant plastic recycling device equipped with a compacting and agglomeration feeding system. It originates from NANTONG. The equipment can directly process whole bags or bundled waste woven materials without prior shredding, efficiently producing high-quality PP recycled pellets. Customization is available based on customer production requirements, with standard models offering capacities ranging from 100 to 1500 kg/h. Suitable for recycling and reusing various types of waste woven bags, it serves as a core piece of equipment in the field of plastic recycling and processing.

Technical Principle

The equipment employs an integrated process combining a compactor and a thickened, wear-resistant single-screw extruder, enabling a complete processing flow from waste woven material to recycled pellets. First, waste woven bags and ton bags can be directly fed into the compactor chamber, where high-speed rotating blades perform powerful shearing and disintegration. Inside the chamber, materials collide at high speed, generating frictional heat that raises their temperature. The originally fluffy woven material contracts and compacts into uniform agglomerates, increasing its bulk density by 3–4 times before being smoothly fed into the extrusion screw, thus preventing bridging and material blockages. Subsequently, the material enters the extrusion stage, undergoing segmented heating and strong shear action to melt and plasticize. Finally, multi-stage filtration through the die removes impurities such as ink and sand, followed by water-cooled pelletizing to produce highly purified PP recycled pellets.

Core Advantages

1. Stable Compactor Feeding: The integrated compactor-agglomeration feeding system ensures no bridging or material blockages, providing uniform and stable feeding to prevent fluctuations in production capacity and guarantee continuous, efficient operation.
2. Eliminates Shredding Process: Whole bags and bundles of waste woven materials can be fed directly into the machine, eliminating the need for additional shredding equipment and processes, significantly reducing upfront processing costs and time.
3. Self-Heating Energy Savings: Materials self-heat through collisions and friction within the compactor, enhancing subsequent plasticization efficiency. Compared to conventional equipment, this approach saves over 12% energy per ton processed, resulting in lower operating costs.
4. Wear-Resistant Screw Adaptable to Contaminated Materials: The alloy wear-resistant screw, nitrogen-treated, handles materials containing substantial impurities, reducing screw wear, lowering maintenance costs, and extending service life.
5. Multi-Stage Filtration Enhances Pellet Quality: Multi-stage filtration effectively removes ink, sand, and other contaminants, yielding highly pure PP recycled pellets with a defect rate kept below 3%, suitable for direct reuse in woven bag production.

Core Product Value

1. Cost Reduction and Efficiency Gains: By eliminating the separate shredding step, the need for 1–2 operators is reduced, cutting labor costs by 35%; meanwhile, energy savings exceed 12% per ton processed, significantly lowering overall production energy expenses.
2. High Production Capacity: Standard models achieve up to 1500 kg/h, with a single line capable of producing up to 36 tons per day, meeting the demands of large-scale recycling operations.
3. Improved Pellet Quality: Multi-stage filtration keeps the defect rate below 3%, allowing high-quality recycled pellets to be directly reused in woven bag manufacturing, promoting resource circulation.
4. Extended Equipment Lifespan: Alloy wear-resistant screws and premium components extend the service life of cutting tools by 120%, reducing maintenance frequency and costs, and prolonging the overall operational life of the equipment.

Target Customer Base

The equipment primarily targets woven bag manufacturers, cement and grain packaging companies, waste plastic recycling plants, and recycled pellet processing facilities—businesses that handle large quantities of waste woven bag materials and require efficient, low-cost recycling equipment to enable resource reuse and enhance economic performance.

Application Scenarios

This equipment is suitable for recycling and pelletizing various types of waste woven bags, including cement woven bags, grain ton bags, container bags, snake skin mesh bags, laminated woven bags, and more. Whether clean waste materials or those contaminated with sand, ink, or other impurities, the machine can process them reliably, producing PP recycled pellets that meet production standards and enabling the circular reuse of used packaging materials.

Solutions to Industry Pain Points

1. Solves the Problem of Bridging and Material Blockages: The compactor-agglomeration feeding system compresses fluffy materials into dense agglomerates, ensuring smooth feeding into the extrusion screw and completely eliminating industry challenges related to bridging and blockages.
2. Removes Extra Costs of Pre-Shredding: The equipment can directly process whole bags and bundles, eliminating the need for separate shredding steps, reducing investment in shredding equipment, labor costs, and processing time, thereby improving overall production efficiency.
3. Addresses Fluctuations in Production Caused by Uneven Feeding: A uniform and stable feeding system ensures consistent, reliable operation, avoiding unpredictable swings in output due to variable feed amounts and maintaining steady production levels.
4. Improves Rapid Screw Wear in Conventional Equipment: Using alloy wear-resistant screws treated with nitrogen, adapted for processing materials with high impurity content, significantly extends screw lifespan, reduces maintenance costs, and minimizes downtime.
5. Tackles Issues of Clogged Screens and Poor Pellet Quality Due to Contaminants: Multi-stage filtration effectively removes impurities, preventing screen clogging while enhancing pellet purity and ensuring quality meets production requirements.
