FIBC Space Bag Granulator

Product Overview

The FIBC Space Bag Granulator is a wear-resistant granulation machine for recycled woven bags, equipped with a compacting and agglomeration feeding system. It is a customized product without a fixed price, tailored to meet the specific production capacity requirements of each customer. This 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 and granulating various types of used woven materials, including cement woven bags, grain bulk bags, container space bags, snake-skin mesh bags, laminated woven bags, and more. It serves as essential auxiliary equipment for woven bag manufacturers, cement and grain packaging companies, waste plastic recycling plants, and recycled pellet processing facilities.

Technical Principle

This granulator employs an integrated process combining a compactor and a thickened, wear-resistant single-screw extruder. The entire workflow achieves efficient conversion from waste material to finished pellets. Used woven bags and bulk bags can be fed directly into the compactor chamber, where high-speed rotating and stationary 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. With a bulk density increased by 3–4 times, the material is smoothly fed into the extrusion screw, effectively preventing bridging and clogging issues associated with loose materials. In the extrusion stage, the material undergoes segmented heating and intense shearing in the screw to achieve melting and plasticization, followed by multi-stage filtration through the die head to remove ink, sand, and other impurities. Finally, water-cooled cutting forms the pellets, all without any additional crushing steps, resulting in a compact and highly efficient process.

Core Advantages

1. Stable and reliable compactor feeding: Utilizing a compacting and agglomeration feeding system, it eliminates bridging and clogging issues, ensuring uniform and stable feeding, thereby preventing fluctuations in production capacity caused by uneven feeding and guaranteeing continuous, stable operation.
2. Eliminates separate shredding step: Allows direct feeding of whole bags or bundles of waste woven materials without prior shredding, significantly simplifying the production process and reducing additional operational steps.
3. Self-heating energy-saving efficiency: Through collisions and friction inside the compactor, the material self-heats, improving plasticization efficiency while reducing external heating energy consumption—saving over 12% electricity per ton compared to conventional equipment.
4. Wear-resistant screw adapted to dirty materials: The screw is made of alloy wear-resistant material, nitrogen-treated for superior durability, enabling efficient processing of materials containing significant impurities, thus slowing down screw wear and lowering maintenance costs.
5. Multi-stage filtration ensures pellet purity: Equipped with a multi-stage filter die head, it effectively removes ink, sand, and other contaminants, producing high-purity PP recycled pellets with a defect rate kept below 3%, ready for direct reuse in woven bag production.

Core Value of the Product

1. Simplified processes reduce costs and boost efficiency: By eliminating the separate shredding step and reducing the need for 1–2 operators, labor costs drop by 35%, while shortening the production cycle and enhancing overall operational efficiency.
2. Energy savings increase profitability: Self-heating plasticization reduces electricity consumption by over 12% per ton, and with a maximum daily output of 36 tons operating continuously, long-term energy cost savings are substantial, further boosting production returns.
3. Wear-resistant design extends service life: The combination of alloy blades and wear-resistant screws increases blade lifespan by 120% and dramatically slows screw wear, reducing downtime for maintenance and extending the overall equipment lifespan.
4. High-quality pellets expand application scope: The produced PP recycled pellets boast high purity and low defect rates, making them suitable for direct reuse in woven bag production without additional purification, saving raw material costs while broadening the range of applications for the pellets.

Target Customer Groups

This FIBC Space Bag Granulator targets woven bag manufacturers, cement packaging companies, grain packaging enterprises, waste plastic recycling plants, and recycled pellet processing facilities—especially businesses with large volumes of used woven material requiring recycling, seeking to streamline production processes, improve pellet quality, and lower operating costs.

Application Scenarios

This equipment is primarily used for recycling and granulating various types of used woven bags, including cement woven bags, grain bulk bags, container space bags, snake-skin mesh bags, laminated woven bags, and more. Whether it’s packaging waste generated during a company’s own production or collected by recycling organizations, these materials can be directly fed into the machine to produce high-quality PP recycled pellets, achieving resource circularity.

Solutions to Industry Pain Points

1. Solves the problem of bridging and clogging when processing fluffy woven materials: The compactor’s agglomeration feeding system compresses loose materials into high-density pellets, completely eliminating bridging and blockages during feeding, ensuring smooth and stable material flow.
2. Removes the extra step of pre-shredding and associated labor costs: The equipment can handle whole bags or bundles directly, eliminating the need for separate shredding equipment and personnel, thus reducing both the shredding process and labor input, lowering overall operating expenses.
3. Addresses production capacity fluctuations caused by uneven feeding: The uniform and stable agglomeration feeding method keeps the amount of material entering the extrusion screw constant, preventing sudden spikes or drops in output due to uneven feeding, thereby ensuring consistent and stable performance.
4. Improves the issue of rapid screw wear and high maintenance costs in conventional equipment: The thickened, wear-resistant screw, crafted from alloy and treated with nitrogen, significantly enhances wear resistance, adapts well to processing materials with high levels of impurities, slows down screw wear, and reduces maintenance frequency and costs.
5. Tackles problems of frequent filter clogging and poor pellet quality caused by dirty materials: The multi-stage filter die head effectively intercepts ink, sand, and other contaminants, preventing filter blockages while enhancing the purity of finished pellets, reducing defect rates, and ensuring pellet quality meets standards for reuse in production.
