Imagine a massive, slowly rotating drum, tumbling and agglomerating powdered fertilizer materials, gradually forming uniform, full granules—that’s the magic of a drum granulator. More than just a piece of production equipment, it’s a rotary artist in the fertilizer industry. Through precise rotational motion, the drum granulator creates an ideal environment for granulation. Within the drum, the material undergoes a complex trajectory: rising against the wall under centrifugal force, falling freely under gravity, and tumbling continuously under friction.This three-dimensional motion ensures that each granule is evenly coated and perfectly spherical. “The true magic of drum granulation lies in its continuity and consistency. Like a tireless craftsman, it produces flawless fertilizer granules 24 hours a day, each one containing a precise nutritional profile.”

The drum granulator is equipped with an advanced PLC control system that monitors key parameters such as speed, inclination angle, and temperature in real time, ensuring stable and repeatable production.

The drum granulator’s outstanding performance relies on the precise coordination of the entire production system, with every link being crucial:

Core Fertilizer Equipment for Modern Fertilizer Production Lines

Raw Material Pretreatment

System Precision crushing, drying, and screening provide ideal raw material conditions for granulation. Automatic batching system devices and high-precision weighing sensors ensure absolutely accurate formula ratios. High-efficiency mixing equipment and a dual-shaft mixer ensure thorough and uniform mixing of raw materials. A rotary drum granulation core ensures granule uniformity and production efficiency. An intelligent drying system and a rotary dryer precisely control granule moisture content. Precision screening and packaging. Multi-layer vibrating screens for grading and an automated packaging line. From raw materials to qualified granular fertilizer, these devices form a seamless production line, transforming agricultural waste and difficult-to-use chemical raw materials that would otherwise be wasted into “energy packs” that nourish crops.
