Double Roller Extrusion Granulator – Low-Power Dry Granulation for Green Production
Product Description
The Energy-Saving Double Roller Extrusion Granulator is a high-efficiency dry granulation machine engineered for minimal energy consumption. It presses powdery raw materials into dense, uniform pellets via adjustable high pressure (0.3-18MPa) without water, binders or drying procedures. Its advanced energy recovery system and high-efficiency motor reduce power use by 55% versus conventional models, while ensuring a granulation rate of over 93%. With a scalable capacity of 0.2-15t/h, it is the top choice for eco-focused enterprises aiming to cut costs and carbon emissions.
Application Scope
Ideal for energy-efficient, eco-friendly granulation scenarios, this machine is widely applied in:
- Fertilizer Industry: Organic-inorganic compound fertilizer, slow-release fertilizer granulation
- Chemical Industry: Fine chemical powder, inorganic salt granulation
- Feed Industry: High-protein feed, additive premix granulation
- New Materials Industry: Battery material powder, ceramic powder granulation
Product Highlights
- 55% Energy Reduction: Integrated energy recovery system captures and reuses extrusion-generated heat; high-efficiency motor cuts power consumption drastically.
- Zero Auxiliary Cost: Dry process eliminates water, binder and drying expenses, avoiding nutrient loss or material contamination.
- Precision Granulation: Adjustable pressure and roller speed ensure uniform particle size (0.6-8mm) and high compressive strength, suitable for automated production lines.
- Low-Maintenance Design: Wear-resistant ceramic roller sleeves extend service life by 2x; modular structure enables quick part replacement with no special tools.
- Full Eco-Compliance: Fully sealed chamber traps 99.8% of dust; zero wastewater discharge meets the strictest environmental standards.
