Double Roller Extrusion Granulator – Energy-Saving Dry Granulation for Cost-Effective Production
Product Overview
The Double Roller Extrusion Granulator is a compact, power-saving dry granulation machine that converts powdery raw materials into high-strength pellets through high-pressure extrusion (0.5-20MPa) without water, binders, or drying steps. Its high-efficiency motor and optimized roller structure reduce energy consumption by 45% compared to standard models, while ensuring a granulation rate of over 92%. With a flexible capacity of 0.3-20t/h, it is perfect for small and medium-sized production lines pursuing energy efficiency and cost reduction.
Application Scope
Ideal for energy-saving granulation scenarios, this machine applies to:
- Fertilizer Sector: Organic fertilizer, compound fertilizer granulation
- Chemical Sector: Inorganic salt, detergent powder processing
- Feed Sector: Premixed feed, additive granulation
- Building Materials Sector: Fly ash, mineral powder granulation
Product Highlights
- 45% Energy Reduction: High-efficiency frequency conversion motor and precision transmission cut power use sharply, slashing operational costs.
- No Auxiliary Energy Cost: Dry process eliminates drying and binder costs, with zero extra energy consumption for supporting procedures.
- Easy Operation & Maintenance: Modular design allows quick roller replacement; simple control panel suits operators with basic training.
- Consistent Pellet Quality: Adjustable pressure ensures uniform particle size (1-10mm) and high hardness, suitable for long-distance transportation.
- Green & Clean: Fully sealed design traps over 99% dust, meeting strict environmental standards without secondary pollution.
