Mesh Bag and Snake Skin Bag Granulator

Product Overview

This is a wear-resistant woven bag recycling granulation machine from the Nantong PURUI brand, specifically designed for recycling and granulating used woven materials such as mesh bags and snake skin bags. It features a dedicated compacting and agglomeration feeding system, enabling direct processing of whole bags or bundles of waste woven material without prior crushing, efficiently producing high-quality PP recycled pellets. As a customized product, the equipment’s configuration can be adjusted according to customer production requirements, with no fixed price. From core components to auxiliary parts, all use premium branded components, ensuring long-term stable operation—making it an efficient capacity‑boosting solution in the field of waste plastic recycling.

Technical Principle

The equipment employs an integrated process combining a compactor and a thickened, wear‑resistant single‑screw extruder, achieving highly efficient full‑process treatment from waste material to recycled pellets. Used woven bags and ton bags can be directly fed into the compactor chamber, where high‑speed rotating and stationary blades perform powerful shearing and disintegration. The material undergoes rapid collisions and friction within the chamber, generating heat and self‑heating; the originally fluffy woven material shrinks and compacts into uniform agglomerates, significantly increasing its bulk density before being smoothly fed into the extrusion screw, completely eliminating issues like bridging or material blockages during feeding. In the extrusion stage, segmented heating combined with a high‑shear screw completes melting and plasticization, followed by multi‑stage filtration through a die head to remove ink, dirt, and other impurities, ultimately resulting in water‑cooled pelletizing. The entire process requires no additional crushing steps, greatly simplifying the production workflow.

Core Advantages

1. Stable feeding with no blockages: Equipped with a compactor‑based agglomeration feeding system, the material is compacted and fed smoothly into the screw, thoroughly resolving the industry‑wide pain point of loose woven material causing bridging and jamming. Uniform, stable feeding ensures consistent production output.
2. Eliminates the crushing step: Whole bags or bundles of waste woven material can be fed directly, removing the need for separate crushing equipment and manual crushing processes, significantly streamlining production workflows and reducing upfront equipment investment and labor costs.
3. Highly energy‑efficient: Relying on self‑frictional preheating to raise material temperature, no additional preheating equipment is required, resulting in higher plasticization efficiency. Compared to traditional machines, this approach saves over 12% energy per ton processed, substantially lowering long-term operating costs.
4. Wear‑resistant and adaptable to dirty materials: The screw is made of alloy wear‑resistant material and treated with nitriding, making it well suited for processing materials with high levels of impurities. Slow wear rates extend equipment maintenance intervals and significantly reduce repair costs.
5. High‑purity pellet output: Multi‑stage filtration through the die head effectively removes ink, dirt, and other contaminants, keeping the defective rate below 3%. The resulting PP recycled pellets are of high purity and can be directly reused in woven bag production.

Core Product Value

1. Streamlined processes reduce costs: By eliminating the separate crushing step, one to two operators can be removed, cutting labor costs by 35% while also saving on the purchase and maintenance of crushing equipment.
2. Boosts production efficiency: The standard model achieves a maximum capacity of 1500 kg/h, with a single line capable of producing up to 36 tons per day, dramatically improving waste plastic recycling efficiency and helping companies expand their production scale.
3. Energy savings and enhanced durability: Self‑preheating plasticization reduces energy consumption by over 12%, while alloy tool life is extended by 120%, leading to significant savings in both energy and equipment maintenance costs over the long term.
4. Ensures high‑quality pellets: With a defective rate kept below 3%, the pellets can be directly reused in woven bag production without additional purification, enhancing the commercial value and application scope of recycled pellets.

Target Customer Groups

This equipment is specially designed for enterprises involved in waste plastic recycling and woven bag production. Its primary target customers include woven bag manufacturers, cement and grain packaging companies, waste plastic recycling plants, and recycled pellet processing facilities—businesses that routinely generate large quantities of used woven materials or require recycled pellets as raw materials. The equipment’s efficient processing capabilities and customizable configurations perfectly align with these production needs.

Application Scenarios

This equipment is primarily used for recycling and granulating various types of used woven materials, including cement woven bags, grain ton bags, container bags, mesh bags, laminated woven bags, and more. Whether it’s waste packaging generated internally by a company or collected through recycling channels, all can be directly fed into the machine for granulation. The high‑quality PP recycled pellets produced can then be reused in woven bag manufacturing, realizing resource circularity—making it ideal for large‑scale waste plastic recycling production lines.

Solutions to Industry Pain Points

1. Addresses the issue of loose woven material causing bridging and jamming: The compactor‑based agglomeration feeding system achieves smooth feeding through self‑compaction, completely avoiding uneven feeding and machine stoppages common in traditional equipment, thus ensuring continuous production.
2. Eliminates crushing process costs: No need to crush materials beforehand, saving on the purchase of crushing equipment, labor costs associated with manual crushing, and time lost during the crushing process, thereby greatly simplifying production workflows and boosting overall efficiency.
3. Solves capacity fluctuation problems: Stable, uniform feeding paired with an efficient plasticization and extrusion structure ensures consistent equipment performance within standard ranges, preventing unpredictable fluctuations caused by uneven feeding.
4. Reduces equipment maintenance costs: Thickened, wear‑resistant screws and high‑quality branded components significantly enhance wear resistance and overall durability, decreasing equipment failure rates and repair expenses, and extending service life.
5. Resolves issues of clogged screens due to dirty materials and poor pellet quality: Multi‑stage filtration through the die head effectively removes impurities, preventing screen blockages that lead to downtime and cleaning, while simultaneously improving pellet purity, reducing defect rates, and ensuring pellet quality meets production reuse requirements.
