Disc Granulator: The Artisan of Efficient Fertilizer Production

Among the diverse equipment in fertilizer production, the disc granulator stands out with its unique working principle and exceptional granulation results, creating a distinctive landscape on the production line. This seemingly simple equipment embodies sophisticated mechanical design and scientific granulation principles.
The disc granulator utilizes an inclined rotating disc to create rolling motion of materials through the combined action of centrifugal force, gravity, and friction, gradually forming uniform spherical granules. This granulation method not only offers simple operation but also allows real-time observation of the granulation process, facilitating immediate adjustment of technical parameters. Compared to other granulation equipment, the disc granulator demonstrates significant advantages including high pelletization rate, uniform granules, and relatively low energy consumption.
In the complete fertilizer production process, the disc granulator plays a crucial connecting role. Front-end chain crusher process raw materials to appropriate fineness, while vertical disc mixer ensure even distribution of various components. When the prepared materials enter the disc granulator, liquid is added through a proper spraying system, forming spherical granules during the disc's rotational movement. Subsequently, the semi-finished granules proceed to dryers for moisture removal, then to coolers for temperature reduction, and finally through screening machines to obtain uniformly sized finished products.
The distinctive feature of the disc granulator lies in its exceptional flexibility and controllability. By adjusting the disc's inclination angle, rotation speed, and rim height, granule size and density can be precisely controlled. This flexibility enables the disc granulator to adapt to different fertilizer formulations—from compound fertilizers to organic fertilizers, from trace element fertilizers to specialized formula fertilizers—all handled with remarkable
