Published on: April 4, 2026 | Author: Sarah Johnson, Plastic Granulation Technology Specialist | Technical Whitepaper: Dual Stage Big Bag Granulation: Maximizing Pellet Quality & Throughput
Big Bag Granulator
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 big bag waste while maintaining precision and consistency. The BG-1500 Dual Stage Big Bag Granulator is engineered for this purpose, featuring a dual stage big bag granulator 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.
The BG-1500’s dual stage big bag granulator design first reduces big bags into fine flakes (5-10mm) in the first stage, then converts those flakes into uniform pellets (2-4mm) in the second stage—resulting in pellets with a 99% uniformity rate. Its powerful motor (90 kW) delivers an output capacity of 800-1500 kg/h, making it ideal for industrial granulator facilities processing thousands of kilograms of big bag waste per day. Additionally, the BG-1500 is equipped with an high-efficiency pelletizer advanced cooling system that prevents pellet deformation, ensuring consistent quality even during 24/7 operation. It is fully compliant with PPWR compliant granulator, CE certified industrial granulator, and ISO standards, making it a reliable choice for global industrial recycling machine operations.
Core Features & Why It Matters
- Dual Stage Design: The first stage shreds big bags into fine flakes (5-10mm), while the second stage granulates those flakes into uniform pellets (2-4mm)—delivering 99% pellet uniformity and superior quality compared to single-stage models.
- High Throughput & Efficiency: A 90 kW (120 HP) motor delivers an output capacity of 800-1500 kg/h, making it ideal for industrial granulatorfacilities processing high volumes of big bag waste. The dual stage big bag granulator design reduces energy consumption by 20% compared to traditional dual-stage granulators.
- Advanced Cooling System: A built-in water cooling system prevents pellet deformation, ensuring consistent quality even during 24/7 operation. This reduces waste by 5% and maximizes the value of the recycled pellets.
- Industrial-Grade Durability & Compliance: Built with heavy-duty carbon steel and replaceable wear parts, the BG-1500 is designed for continuous industrial granulator It is fully compliant with PPWR compliant granulator(EC 2025/40), CE certified industrial granulator (EN 60204-1), and ISO 9001:2015, meeting global industrial recycling machine and environmental standards.
