Purui Cement Woven Bag Granulator

Product Overview

The Purui brand’s cement woven bag granulator is a wear-resistant equipment for recycling and granulating woven bags. It is a customized product with no fixed price, tailored to meet the customer’s production requirements. The machine is equipped with a dedicated compacting and agglomeration feeding system, capable of directly processing whole bags or bundles of used woven materials without prior crushing. Leveraging an integrated process combining compaction and a thickened, wear-resistant single-screw design, it efficiently produces high-quality PP recycled pellets, suitable for various scenarios involving the recovery and reuse of waste woven materials, helping plastic recycling enterprises achieve efficient, low-cost material regeneration.

Technical Principle

This equipment employs an integrated process of compaction and a thickened, wear-resistant single-screw design, enabling a complete processing flow from used woven materials to PP recycled pellets. First, used woven bags and ton bags can be directly fed into the compactor chamber, where high-speed rotating blades perform powerful shearing and disassembly. 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, increasing its bulk density by 3–4 times before being smoothly fed into the extrusion screw. Subsequently, during the extrusion stage, segmented heating combined with a high-shear screw completes melting and plasticization, followed by multi-stage filtration through a die to remove impurities such as ink and sand, ultimately resulting in water-cooled pelletizing and shaping, yielding high-quality PP recycled pellets.

Core Advantages

1. Stable and worry-free compaction feeding: The equipped compacting and agglomeration feeding system prevents bridging and blockages caused by fluffy woven materials, ensuring uniform and steady feeding, thus maintaining continuous, stable operation without fluctuations in output due to uneven feeding.
2. Eliminates crushing steps, reducing costs and boosting efficiency: Whole bags or bundles of used woven materials can be fed directly into the machine, eliminating the need for additional crushing equipment and separate crushing processes, significantly cutting equipment investment and labor costs, reducing staffing by 1–2 operators, and lowering labor expenses by 35%.
3. Self-friction preheating for energy savings and high efficiency: Material heats up naturally through collisions and friction inside the compactor, enhancing plasticization while reducing external heating energy consumption; each ton processed saves over 12% electricity, resulting in better operating costs.
4. Wear-resistant screw adapted for processing dirty materials: Featuring an alloy wear-resistant screw treated with nitrogen, offering excellent wear resistance, it can handle materials containing numerous impurities, slowing down screw wear, reducing maintenance costs, and extending the service life of alloy tools by 120%.
5. Multi-stage filtration ensures pellet quality: Through multi-stage filtration via the die, impurities like ink and sand are effectively removed, producing PP recycled pellets with high purity and keeping the defect rate below 3%, allowing direct reuse in woven bag production and increasing the value of recycled materials.

The machine helps these enterprises achieve efficient material regeneration, enhance resource utilization, and reduce production costs.

Application Scenarios

The cement woven bag granulator is suitable for various scenarios involving the recycling and granulation of waste woven materials, including cement woven bags, grain ton bags, bulk containers, snake-skin mesh bags, laminated woven bags, and more. Whether dealing with whole bags or bundled fluffy materials, they can all be directly fed into the machine for processing, producing high-quality PP recycled pellets that can be reused in manufacturing various types of woven bags, realizing circular resource utilization.

Solutions to Industry Pain Points

1. Addresses the issue of fluffy woven materials causing bridging and jamming in feeders: The compacting and agglomeration feeding system compresses fluffy materials into high-density agglomerates, preventing bridging and blockages during feeding and ensuring continuous, stable operation.
2. Solves the pain point of requiring prior crushing, which adds extra steps and labor costs: The machine can directly process whole bags or bundles without prior crushing, eliminating the crushing step and associated labor input, reducing staffing by 1–2 operators and cutting labor costs by 35%.
3. Tackles the problem of uneven feeding leading to large output fluctuations: Uniform, stable agglomerate feeding ensures consistent screw feed rates, avoiding unpredictable swings in production output and delivering steady productivity.
4. Resolves the issue of ordinary equipment featuring rapidly worn screws and high maintenance costs: Using alloy wear-resistant screws treated with nitrogen, significantly improving wear resistance and adapting to processing highly impure materials, extending the service life of alloy tools by 120% and reducing equipment repair frequency and costs.
5. Addresses the challenge of dirty materials containing many impurities, easily clogging screens and compromising pellet quality: Multi-stage filtration effectively removes ink, sand, and other impurities, preventing screen clogging while ensuring pellet purity, keeping the defect rate below 3% and meeting the quality standards required for direct reuse in production.
