Double Roller Granulator: The Ideal Dry Granulation Machine for Fertilizer Production

Double Roller Granulator is a powerful and energy-efficient machine used in the dry granulation process, especially for compound fertilizer (NPK) production. It works without the need for drying or cooling systems, making it a cost-effective solution for factories looking to produce high-strength fertilizer granules with low moisture content.

Whether you’re a large fertilizer manufacturer or a small-scale entrepreneur, this granulator is the perfect equipment for compressing powdered materials into uniform granules.

How a Double Roller Granulator Works — Step-by-Step Dry Granulation Process

1. Feeding — Raw materials such as urea, ammonium sulfate, and other NPK components are fed into the machine.
2. Compaction — The powders are pressed between two counter-rotating rollers to form dense sheets or flakes.
3. Crushing — The sheets are crushed into granules by a built-in crusher.
4. Screening — Oversized or undersized particles are separated, and only qualified granules are discharged.
5. Recycling — Unqualified particles are sent back for re-compaction.

Key Advantages of Using a Double Roller Granulator in Your Fertilizer Plant

✅ Energy Saving — No need for drying or cooling reduces electricity consumption. ✅ Cost-Effective — Lower equipment and operational cost compared to wet granulation lines.

This machine is particularly effective for NPK compound fertilizer , bentonite-based fertilizers , and industrial chemical granules .

Applications of Double Roller Granulators: Beyond Just NPK Fertilizer

• Bentonite granules for cat litter or desiccants
• Magnesium sulfate or zinc sulfate granules
• Detergent powder compaction
• Mineral and salt pelletizing
