Among the various pathways for transforming powdered organic fertilizer into commercial granules, the disc granulator plays the role of a focused and elegant "spherical artist" with its unique working principle. It does not rely on powerful mechanical pressure but utilizes ingenious rotation and gravity to allow fine powder to naturally grow into uniform, rounded granules through a gentle "snowballing" process. This nearly biomimetic forming method grants it a unique niche in organic fertilizer production, especially where granule integrity and biological activity are of high importance.
Core Advantage: "Growth-Type" Granulation Dancing with Gravity and Centrifugal Force
The excellence of the disc granulator lies in its profound understanding of the essence of granulation—agglomeration, not compaction.
Perfect Sphericity & Uniformity: The inclined, rotating disc provides a continuous tumbling bed for the material. With the addition of an appropriate liquid binder (water or slurry), fine powders gradually grow through mutual coalescence and layering, forming granules with excellent sphericity, smooth surfaces, and uniform particle size. Such granules have good flowability and high commercial appeal.
Unparalleled Flexibility: Granule size can be steplessly and real-time adjusted by changing the disc inclination angle, rotation speed, and retention time, without the need to replace molds. This flexibility is highly valuable for producing multiple product specifications or adapting to raw material fluctuations.
Gentle Process Preservation: As a typical wet granulation method, the entire process generates almost no high temperature or pressure, maximizing the protection of heat-sensitive active ingredients in the raw materials, such as beneficial microbial agents and enzymes. This is crucial for producing high-end bio-organic fertilizers.
Low Energy Consumption & Easy Maintenance: The structure is relatively simple, with power consumption mainly for driving the disc rota
