Due to its high efficiency, stability, and ease of operation and maintenance, the rotary drum granulator truly makes organic fertilizer production lines more worry-free. Specific advantages are as follows:

1. High degree of automation: The rotary drum granulator utilizes an automated control system for easy operation, reducing the need for manual labor and improving production efficiency.

2. High granule strength: The granules formed through rolling compaction are dense and resistant to breakage, improving product quality and yield. The high granule strength of the rotary drum granulator significantly increases bulk density compared to other granulation methods.

3. High adjustability: The rotary drum granulator can flexibly control granule size, typically between 2 and 8 mm, by adjusting parameters such as speed, inclination angle, and humidity. This adjustability allows the equipment to adapt to different production needs and raw material characteristics.

4. Continuous production: The rotary drum granulator enables continuous production, making it suitable for large-scale processing. Its continuous operation significantly improves production efficiency and reduces downtime during production.

5. Easy maintenance: The rotary drum granulator has a simple structure, relatively few parts, and low maintenance costs. The equipment's casing is constructed of thickened seamless steel pipe, making it durable and virtually deformation-resistant. Maintenance is also simple, requiring only regular cleaning and lubrication of components such as gears.

6. Significant Economic Benefits: The rotary drum granulator requires minimal investment, delivers rapid results, and offers reliable performance. Its pelletizing rate reaches 90%, with minimal return material and a small particle size that allows for re-granulation. These advantages make the rotary drum granulator highly economical for use in organic fertilizer production lines.
