Rotary Drum Granulator Machine for Continuous Granulation with Wide Material Compatibility and Stable Granule Quality

The Drum Granulator Machine is a key piece of equipment for large-scale fertilizer manufacturing, designed to convert powdery and mixed fertilizer materials into uniform granular products. With a continuous rotary granulation process, the machine improves pellet formation efficiency and provides stable operation for organic fertilizer production lines, NPK fertilizer plants, and compound fertilizer manufacturing projects.

The rotary drum granulator uses a rotating cylinder to continuously mix, roll, and shape materials under controlled moisture conditions. It is suitable for processing composted organic materials, fertilizer mixtures, and various raw materials into high-quality fertilizer pellets with improved appearance, storage, and transportation performance.

The drum granulator adopts a rotating drum structure that allows materials to move continuously inside the cylinder. The rolling and mixing action promotes particle growth and helps produce more uniform fertilizer granules.

Designed for industrial fertilizer manufacturing, the equipment supports continuous operation and can be integrated with complete fertilizer production lines, including crushers, mixers, dryers, coolers, screening machines, and packaging systems.

The machine can process different fertilizer materials, including:

• Organic compost materials
• Livestock manure
• Agricultural waste
• NPK fertilizer mixtures
• Compound fertilizer raw materials

This flexibility makes it suitable for various fertilizer production applications.

Through optimized rotation and material mixing, the drum granulator helps improve granule formation and consistency, producing fertilizer pellets suitable for commercial agricultural use.

The robust drum structure and reliable transmission system support long-term operation in demanding production environments. The equipment can be customized according to raw materials, production capacity, and factory layout.

The Rotary Drum Granulator is widely used in:

• Organic fertilizer manufacturing plants
• NPK fertilizer production lines
• Compound fertilizer factories
• Agricultural waste recycling projects
• Commercial fertilizer processing facilities

It is especially suitable for enterprises requiring continuous production and stable fertilizer pelletizing performance.

1. Material Preparation
   Raw materials are crushed, mixed, and adjusted to suitable moisture conditions before entering the granulator.
2. Rotary Granulation
   Materials enter the rotating drum, where continuous rolling and mixing help small particles gradually combine into larger fertilizer pellets.
3. Particle Formation
   With proper moisture and bonding conditions, the granules become more compact and uniform.
4. Post-Processing
   Finished granules are sent to drying, cooling, screening, coating, and packaging processes according to production requirements.

The Drum Granulator Machine provides an efficient and practical pelletizing solution for fertilizer manufacturers seeking reliable production, flexible application, and high-quality granular fertilizer products.
