Rotary Drum Granulator: Core Equipment in 10,000-Ton Production Lines, Supporting Large-Scale Organic Fertilizer Production

With the national push for organic fertilizer to replace chemical fertilizer, large-scale and standardized production has become the mainstream of industry development. As the core equipment of 10,000-ton organic fertilizer production lines, the rotary drum granulator, with its ultra-high capacity, superior durability, and high raw material adaptability, has become the preferred equipment for large-scale organic fertilizer production bases. The rotary drum granulator features a horizontal long cylinder structure. The cylinder body is made of thickened steel plate and equipped with external rollers, support rollers, and thrust rollers, ensuring smooth and vibration-free operation. The internal structure is divided into a mixing and granulation zone and a polishing and granulation zone. Under the action of drum rotation, lifting plates, and micro-spraying, the material gradually agglomerates and forms particles. The polishing zone at the tail further optimizes the roundness and density of the particles, achieving continuous production. The biggest advantage of this equipment lies in its high capacity and versatility, capable of handling a range of materials. With an hourly capacity of 5-15 tons, it can operate continuously for 24 hours and easily process various complex organic materials such as cow manure, sheep manure, mushroom residue, sludge, and straw. It has relaxed requirements regarding raw material fineness and moisture content, and the organic fertilizer production line has a high tolerance for errors. Although the pelletizing rate is between 40% and 60%, the overall finished product rate can remain stable with a well-equipped screening and return system. With its ultra-long service life, extremely low maintenance costs, and large-scale production capacity, the rotary drum granulator has become a core guarantee for large-scale organic fertilizer projects to achieve low-cost, high-volume production, helping the industry move towards a new stage of intensive development.
