Big Bag Granulator
After shredding big 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 BG-1000 Big Bag Granulator (single stage granulator) is engineered to simplify this process, combining shredding and granulation into a single, efficient system that produces high-qualityPP big bag granulator/PE big bag granulator pellets from big 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.
Unlike dual-stage granulators that require separate shredding and pelletizing steps, the BG-1000 integrates a single stage granulator design, reducing equipment footprint by 40% and energy costs by 25%. Its advanced dust collection system reduces dust emission to less than 10 mg/m³, meeting EU air quality standards (EN 13229) and creating a safer working environment for operators. The BG-1000 is also PPWR compliant granulator, ensuring that the pellets produced meet mandatory recycled content requirements for plastic packaging—maximizing the value of your big bag waste.
Big Bag Granulator
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 40% and energy costs by 25% compared to dual-stage granulators.
- Low Dust Emission: An advanced dust collection system captures 99% of dust particles, reducing emission to <10 mg/m³. This meets EN 13229 air quality standards and creates a safer, cleaner working environment for operators.
- High-Quality Pellets: A precision-machined rotor and adjustable screen ensure uniform pellet size (2-5mm), with a pelletizing efficiency of 98%. This produces high-quality regrind that can be directly reused in injection molding, extrusion, or blow molding processes.
- PPWR & Compliance Ready: Fully compliant with PPWR compliant granulator(EC 2025/40), the BG-1000 produces pellets that meet mandatory recycled content requirements for plastic packaging, maximizing the value of your big bag waste. It also holds CE certified granulator (EN 60204-1) and ISO 9001:2015 certifications.

FAQ (Featured Snippet Optimized)
- Q: What is the difference between single stage and dual stage big bag granulators?A: Single stage granulators (like the BG-1000) combine shredding and granulation into one integrated system, reducing footprint and energy costs; dual-stage models require separate shredding and pelletizing steps.
- Q: Can the BG-1000 process shredded big bag flakes directly?A: Yes, it can process shredded PP/PE big bag flakes (10-50mm) directly, eliminating the need for pre-processing and streamlining the recycling workflow.
- Q: What is the quality of the pellets produced by the BG-1000?A: It produces high-quality, uniform pellets (2-5mm) with 98% pelletizing efficiency, suitable for direct reuse in injection molding, extrusion, and blow molding.
- Q: How does the BG-1000 reduce dust emission?A: It features an advanced dust collection system that captures 99% of dust particles, reducing emission to <10 mg/m³ and meeting EN 13229 air quality standards.
