In large-scale fertilizer production, the rotary drum granulator, with its continuous and stable operation and compatibility with multiple fertilizer types, serves as a critical link between raw material mixing and pellet forming. It is particularly well-suited to the efficient production needs of medium- and large-scale enterprises, ensuring consistent pellet quality while reducing manual intervention costs.
Its core advantages lie in its “continuous operation” and adaptability. Firstly, the rotary drum granulator can operate continuously 24 hours a day, processing 5-50 tons/hour without frequent downtime adjustments, perfectly matching the batch production rhythm of fertilizer production lines.
Secondly, by adjusting the binder dosage, drum speed (low speed is suitable for sticky raw materials, high speed is suitable for loose raw materials), and tilt angle (to control material residence time), it can accommodate a variety of fertilizer types, including organic fertilizers, compound fertilizers, and organic-inorganic mixed fertilizers. It can even process organic fertilizers containing small amounts of fiber (the lifting plate design prevents fiber entanglement). In addition, the granule forming rate of the rotary drum granulator can reach over 85%, and the granules are highly rounded and of moderate hardness. No complicated crushing and screening are required afterwards, and they can directly enter the drying stage, which greatly simplifies the production process and provides a cost-effective solution for fertilizer companies to balance “capacity increase” and “quality stability”.
