Recycling Granulator for Laminated Woven Bags

Product Overview

The recycling granulator for laminated woven bags is a wear-resistant granulation machine equipped with a compacting and agglomeration feeding system. It is a customized product without a fixed price, tailored to meet the specific production requirements of each customer. The equipment can directly process whole bags of waste woven materials without prior shredding, efficiently producing high-quality PP recycled pellets. It is suitable for recycling various types of used plastic packaging, including cement woven bags, grain bulk bags, containerized space bags, snake-skin mesh bags, and laminated woven bags, serving a wide range of customers such as woven bag manufacturers, cement and grain packaging companies, waste plastic recycling plants, and recycled pellet processing facilities.

Technical Principle

This equipment employs an integrated process combining a compactor and a thickened, wear-resistant single-screw extruder to complete the entire processing flow from waste woven materials to PP recycled pellets. Used woven bags and bulk bags can be fed directly into the compactor chamber, where high-speed rotating blades perform powerful shearing and disintegration. As the material collides and rubs at high speed within the chamber, friction generates heat, causing the originally fluffy woven material to contract and compact into uniform agglomerates. Once the bulk density significantly increases, the material is smoothly fed into the extrusion screw. Inside the screw, segmented heating combined with strong shear action melts and plastifies the material, followed by multi-stage filtration through the die head to remove ink, sand, and other impurities. Finally, water-cooled cutting forms the pellets, yielding high-quality PP recycled pellets.

Core Advantages

1. Stable compactor feeding: Utilizes a compacting and agglomeration feeding system that eliminates bridging and material blockages, ensuring uniform and stable feeding, effectively preventing fluctuations in production capacity caused by uneven feeding, thus guaranteeing continuous, stable operation.
2. Eliminates the need for shredding: Can directly process whole bags or bundles of waste woven materials without requiring separate shredding equipment, reducing additional processing steps and lowering production preparation costs.
3. Efficient energy-saving plasticization: Material self-heats through friction, eliminating the need for additional preheating equipment, resulting in higher plasticization efficiency while significantly reducing electricity consumption—saving over 12% per ton processed.
4. Wear-resistant adaptation to dirty materials: The screw is made of alloy wear-resistant material, nitrogen-treated and thickened, making it well-suited for processing materials containing substantial impurities, thereby extending the screw’s service life and reducing maintenance costs.
5. Multi-stage filtration for impurity removal: Equipped with a multi-stage filter die head, effectively removing ink, sand, and other contaminants, producing PP recycled pellets of high purity with a defect rate kept below 3%, ready for direct reuse in woven bag production.

Core Value of the Product

1. Simplifies the production process: By eliminating the separate shredding step and reducing the workforce by 1–2 operators, labor costs drop by 35%, while shortening preparation time and boosting overall production efficiency.
2. Saves energy and reduces consumption: Relying on material self-heating through friction, the equipment saves over 12% electricity per ton processed, significantly lowering long-term operating costs and aligning with green manufacturing principles.
3. High and stable output: With standard models capable of producing 100–1500 kg/h, a single line can generate up to 36 tons per day under continuous operation, supported by a stable feeding system that ensures consistent production capacity to meet large-scale manufacturing needs.
4. Extends equipment lifespan: Alloy tooling extends service life by 120%, while the thickened, wear-resistant screw handles dirty materials, reducing maintenance frequency and costs, and minimizing the risk of production interruptions.
5. Produces high-quality pellets: Multi-stage filtration keeps the defect rate below 3%, enabling the produced PP recycled pellets to be directly reused in woven bag production, enhancing material circulation and creating greater economic value.

Target Customer Groups

Woven bag manufacturers, cement packaging companies, grain packaging enterprises, waste plastic recycling plants, and recycled pellet processing facilities—especially those with large-scale needs for recycling and granulating used woven materials—who seek to simplify their production processes, reduce costs, and improve pellet quality.

Application Scenarios

This equipment is primarily used for recycling and granulating various types of used plastic woven bags, including cement woven bags, grain bulk bags, containerized space bags, snake-skin mesh bags, laminated woven bags, and other discarded packaging materials. Whether handling batch processing at small recycling plants or scaling up production at large recycled pellet processing facilities, the equipment adapts to different capacity requirements, efficiently producing high-quality PP recycled pellets and enabling the circular reuse of waste materials.

Solving Industry Pain Points

1. Addresses the issue of fluffy woven materials causing bridging and jamming in feeders: The compactor’s agglomeration feeding system compresses loose materials into uniform pellets, preventing bridging and blockages during feeding and ensuring smooth, stable material flow.
2. Eliminates extra costs associated with pre-shredding: The equipment can directly process whole bags or bundles without requiring separate shredding steps, reducing investment in shredding equipment, labor costs, and processing time, thus lowering overall production expenses.
3. Mitigates capacity fluctuations caused by uneven feeding: Stable agglomeration feeding ensures uniform material input into the extrusion screw, avoiding instability due to variable feeding volumes and maintaining consistent output.
4. Reduces screw wear and maintenance costs: The thickened, wear-resistant screw is designed to handle materials with high levels of impurities, offering longer service life compared to standard equipment, decreasing maintenance frequency and replacement costs, and minimizing the risk of production interruptions.
5. Solves problems of clogged screens and poor pellet quality: The multi-stage filter die head effectively removes impurities, preventing screen blockages while improving pellet purity, keeping the defect rate below 3% and ensuring pellet quality meets the requirements for reuse in production.
