Rotary Drum Granulator: The Core Equipment in Fertilizer Production

In modern fertilizer production, the rotary drum granulator, with its unique working principle and exceptional granulation效果, has become an indispensable key equipment in the fertilizer production line. This seemingly simple machine carries the important mission of transforming powdered raw materials into uniform granules.
Through its rotating drum and precise spraying system, the rotary drum granulator gradually forms uniform granules from moist powdered materials during the rolling process. This granulation method is not only highly efficient but also produces granules with high strength, good roundness, and uniform particle size. Compared to traditional granulation methods, rotary drum granulation enables continuous production, significantly improving production efficiency.
In a complete fertilizer production line, the rotary drum granulator typically works in close coordination with other fertilizer equipment. The front-end chain crusher is responsible for breaking raw materials into suitable particle sizes, while the vertical disc mixer ensures thorough blending of various ingredients. When materials enter the rotary drum granulator, appropriate liquid is added through the spraying system, forming granules under the rotation of the drum. Subsequently, the granulated material moves to the dryer to remove excess moisture, then to the cooler for temperature reduction, and finally through the screening machine for classification to obtain qualified products.
The advantages of the rotary drum granulator are reflected not only in its granulation but also in its wide applicability. Whether for compound fertilizers, organic fertilizers, or various specialized fertilizers, the rotary drum granulator can handle them all. Its unique granulation principle results in more uniform product particles, which not only enhances the product's commercial appeal but also facilitates better crop absorption and utilization.
