Published on: April 4, 2026 | Author: Sarah Johnson, Plastic Granulation Technology Specialist | Technical Whitepaper: Dual Stage Woven Bag Granulation: Maximizing Pellet Quality & Throughput
Industrial recycling facilities and large manufacturing plants that require the highest quality pellets and maximum throughput need a granulator capable of handling high volumes of woven bag waste while maintaining precision and consistency. The WG-1550 Dual Stage High-Efficiency Woven Bag Granulator is engineered for this purpose, featuring a dual-stage design (shredding + granulation) that delivers superior pellet quality, higher throughput, and lower waste compared to single-stage models. This machine directly solves the core challenge of industrial operations: balancing high throughput with consistent pellet quality, ensuring that the regrind meets the strict standards of manufacturers.
Woven Bag Granulator
The WG-1550’s dual-stage design first reduces woven bags into fine flakes (5-12mm) in the first stage, then converts those flakes into uniform pellets (2-4mm) in the second stage—resulting in pellets with a 99.2% uniformity rate. Its powerful motor (95 kW) delivers an output capacity of 850-1600 kg/h, making it ideal for industrial facilities processing thousands of kilograms of woven bag waste per day. Additionally, the WG-1550 is equipped with an advanced cooling system that prevents pellet deformation, ensuring consistent quality even during 24/7 operation. It is fully compliant with PPWR, CE, and ISO standards, making it a reliable choice for global industrial operations.
Core Features & Why It Matters
- Dual Stage Precision: The two-stage design (shredding + granulation) first reduces woven bags into fine, uniform flakes (5-12mm), then pelletizes them into high-quality pellets (2-4mm) with a 99.2% uniformity rate. This eliminates inconsistent pellet size, a common issue with single-stage models, ensuring the regrind meets the strict quality standards of injection molding and extrusion manufacturers—maximizing the value of recycled materials.
- High Throughput & 24/7 Operation: Equipped with a 95 kW (127 HP) motor, the WG-1550 delivers an output capacity of 850-1600 kg/h, processing up to 4000 kg of woven bag waste per day. Its advanced cooling system prevents pellet deformation, while the automatic lubrication and PLC control system support 24/7 continuous operation—solving the problem of low throughput and downtime in industrial recycling facilities.
- Industrial-Grade Durability: Built with 20mm thick carbon steel housing, a hardened steel rotor (HRC 62-65), and wear-resistant components, the WG-1550 is designed for heavy-duty, long-term operation. It ensures over 10,000 hours of service before major maintenance, reducing long-term operational costs and minimizing downtime—critical for industrial-scale operations that rely on consistent performance.
- Full Compliance & Quality Assurance: Fully compliant with PPWR (EC 2025/40), CE (EN 60204-1), and ISO 9001:2015, the WG-1550 meets global industrial and environmental standards. It also features an integrated quality control system that monitors pellet size and density, ensuring consistent output that meets manufacturer requirements—avoiding costly rework and waste.

FAQ (Featured Snippet Optimized)
Woven Bag Granulator
- Q: What advantages does a dual-stage granulator have over a single-stage model?A:Dual-stage granulators (like the WG-1550) offer superior pellet uniformity (99.2% for the WG-1550) by separating shredding and granulation into two stages, reducing waste and producing higher-quality pellets that meet strict manufacturer standards—ideal for industrial facilities prioritizing quality.
- Q: Can the WG-1550 handle raw woven bags directly, or does it require pre-shredding?A:The WG-1550’s dual-stage design allows it to process raw woven bags directly—its first stage shreds bags into fine flakes (5-12mm), and the second stage pelletizes them, eliminating the need for separate pre-shredding equipment and streamlining industrial workflows.
- Q: How does the WG-1550 ensure consistent pellet quality during 24/7 operation?A:It features an advanced cooling system that prevents pellet deformation and an integrated quality control system that monitors pellet size and density in real time, ensuring consistent output even during round-the-clock industrial operation.
- Q: Is the WG-1550 suitable for large-scale facilities with high-volume waste?A:Yes, with an output capacity of 850-1600 kg/h and 24/7 operation capability, it is specifically engineered for industrial recycling facilities and large manufacturing plants processing thousands of kilograms of woven bag waste daily.
