The granulation process of the disc fertilizer granulator is both scientific and ingenious, and mainly includes the following key steps:

First, the material preparation link is crucial. The powdered fertilizer raw materials with good proportions, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer and various trace element additives, are accurately mixed according to a specific formula to ensure the balance of fertilizer nutrients. These raw materials usually undergo preliminary crushing and drying to achieve the appropriate fineness and humidity, laying the foundation for subsequent granulation.

Then, turn on the disc fertilizer granulator, and the specially made inclined rotating disc in the machine will start immediately. Driven by power, the disc rotates at a stable speed, and the material is transported to the rotating disc.

Inside the disc, there is a unique granulation mechanism. On the one hand, as the disc rotates, the material continues to roll, collide, and gradually agglomerate under the action of centrifugal force. On the other hand, the binder solution is sprayed in time through the spray device installed above the disc. The binder is like “glue”, accurately attached to the surface of the material particles, making the originally loose material powder easier to bond and form. During the continuous tumbling and bonding process, the material particles gradually grow from small to large, forming preliminary fertilizer particles.

Then, the formed fertilizer particles will move to the edge as the disc rotates and pass through the screening device. The screening device is like a strict “quality inspector”, screening out large and small particles that do not meet the size requirements. The large particles return to the disc for reprocessing, and the small particles participate in the granulation process again. Only finished particles with qualified sizes can pass smoothly.

Finally, the qualified fertilizer particles enter the subsequent drying and cooling process to remove excess water and stabilize the particle shape, thus completing the gorgeous transformation from powdered raw materials to round and compact fertilizer particles, providing high-quality fertilizer products for agricultural production.
