New type two in one organic fertilizer granulator’s anti-caking technology spans the entire workflow—comprising homogenization via pulverization, precise moisture control, and densification—establishing a three-tiered defense system at the source. The first line of defense utilizes a pre-granulation pulverization module to reduce materials to a uniform, fine powder, eliminating risks associated with uneven particle size, such as poor granulation quality and increased moisture absorption. The second line of defense precisely regulates the feed moisture content within the critical 22%–38% range; this ensures the formation of necessary liquid bridges for nucleation while utilizing frictional heat generated during granulation to evaporate surface moisture, thereby significantly lowering the final moisture content. The third line of defense employs an anti-sticking inner lining combined with centrifugal densification in the rounding zone; this produces dense, uniform granules with smooth surfaces, drastically reducing porosity and delaying crystal bridge formation, resulting in a stable granulation rate exceeding 90%. These three interconnected defenses fundamentally resolve the industry-wide challenge of organic fertilizer caking.
In summary, the anti-caking strategy of this new type two-in-one granulator is integrated into the entire process—pulverization/homogenization, precise moisture control, and densification—rather than relying on single additives or remedial measures. By eliminating particle-size issues through pre-pulverization, cutting off chemical triggers via precise moisture control, and ensuring physical quality through anti-stick lining and densification, the system employs a progressive three-tiered defense to minimize caking risks at the source. For enterprises committed to quality, effectively leveraging this technical logic is far more fundamental and efficient than resorting to post-process additions of anti-caking agents or repeated screening and crushing.
