After shredding woven bags into flakes, the next critical step in the recycling process is granulation—converting those flakes into uniform pellets that can be reused in manufacturing. The WG-1050 Woven Bag Granulator (Single Stage Pelletizer) is engineered to simplify this process, combining shredding and granulation into a single, efficient system that produces high-quality PP/PE pellets from woven bag waste. This machine directly solves the core pain points of traditional granulation: high dust emission, inconsistent pellet size, and excessive energy consumption—delivering a cost-effective, compliant solution for recycling facilities of all sizes.
Woven Bag Granulator
Unlike dual-stage granulators that require separate shredding and pelletizing steps, the WG-1050 integrates a single-stage design, reducing equipment footprint by 42% and energy costs by 28%. Its advanced dust collection system reduces dust emission to less than 8 mg/m³, meeting EU air quality standards (EN 13229) and creating a safer working environment for operators. The WG-1050 is also PPWR compliant, ensuring that the pellets produced meet mandatory recycled content requirements for plastic packaging—maximizing the value of your woven bag waste.
Core Features & Why It Matters
- Single Stage Integration: Combines shredding and granulation into one integrated system, eliminating the need for separate equipment—reducing footprint by 42% and energy costs by 28% compared to dual-stage granulators. This solves the problem of limited space and high energy consumption for mid-sized facilities looking to optimize their workflow.
- Low Dust Emission: An advanced dust collection system captures 99.2% of dust particles, reducing emission to <8 mg/m³. This meets EN 13229 air quality standards and creates a safer, cleaner working environment for operators—addressing health and safety concerns in recycling facilities and ensuring compliance with workplace regulations.
- High-Quality Pellets: A precision-machined rotor and adjustable screen ensure uniform pellet size (2-5mm), with a pelletizing efficiency of 98.5%. This produces high-quality regrind that can be directly reused in injection molding, extrusion, or blow molding processes—maximizing the value of recycled woven bag materials and opening up revenue streams.
- PPWR & Compliance Ready: Fully compliant with PPWR (EC 2025/40), the WG-1050 produces pellets that meet mandatory recycled content requirements for plastic packaging. It also holds CE (EN 60204-1) and ISO 9001:2015 certifications—ensuring market access for recycled pellets and avoiding compliance penalties.

FAQ (Featured Snippet Optimized)
- Q: What is the difference between single stage and dual stage woven bag granulators?A:Single stage granulators (like the WG-1050) combine shredding and granulation into one integrated system, reducing footprint and energy costs; dual-stage models require separate shredding and pelletizing steps—making single-stage ideal for mid-sized facilities.
- Q: Can the WG-1050 process shredded woven bag flakes directly?A:Yes, it can process shredded PP/PE woven bag flakes (10-55mm) directly, eliminating the need for pre-processing and streamlining the recycling workflow to save time and labor.
- Q: What is the quality of the pellets produced by the WG-1050?A:It produces high-quality, uniform pellets (2-5mm) with 98.5% pelletizing efficiency, suitable for direct reuse in injection molding, extrusion, and blow molding—meeting manufacturer standards for recycled materials.
- Q: How to reduce dust emission in woven bag granulation?A:Choose a granulator with an advanced dust collection system (like the WG-1050), which captures 99.2% of dust particles and reduces emission to <8 mg/m³, meeting EU air quality standards and protecting your team.
