When selecting organic fertilizer granulation equipment, there is a fundamental dividing line that is even more critical than standard equipment specifications: the input moisture content range. For the same type of composted livestock manure, a moisture content of 25%–35% is suitable for disc agglomeration; if it drops below 5%, dry extrusion is the only viable option; meanwhile, production...
Differences in “Controllability” for Organic Fertilizer Granulation: Process Logic of Disc, Two-in-One, and Double-Roller Extrusion Methods
When selecting organic fertilizer granulation equipment, there is a crucial yet rarely discussed dimension: process controllability. While all three methods transform decomposed materials into granules, they differ in their control mechanisms: the disc granulator relies on the operator’s real-time visual assessment of the material’s tumbling state; the double-roller press granulator...

Three Quality Indicators for Organic Fertilizer Granulation: Granulation Rate, Sphericity, and Viable Bacteria Survival Rate
Evaluations of organic fertilizer granulation effectiveness have long relied on subjective visual assessments—specifically, how round the granules look. However, a product’s true market competitiveness is determined by a set of quantifiable engineering metrics: granulation rate, sphericity, granule compressive strength, and—unique to bio-organic fertilizers—the survival rate of viable...

Fertilizer granule shape is often dismissed as a mere matter of aesthetics. In actual production, however, the differences between spherical, cylindrical, and flake-like shapes directly determine whether material bins will bridge, whether segregation will occur during conveying, and whether packaging scales can discharge material steadily. Granule shape is not merely a byproduct of the granulator; it is the starting point for the operational logic of the entire production line.
Bulk Blended Fertilizer (BB Fertilizer): Spherical granules offer good flowability but are prone to segregation. NPK blending lines process finished granules such as urea, ammonium phosphate, and potassium chloride. These materials typically leave the factory in spherical or near-spherical shapes, characterized by low angles of repose and excellent flowability. NPK blending machines utilize...
Why can’t a disc granulator for bio-organic fertilizer be used for ordinary organic fertilizer?
At first glance, disc granulators look alike—featuring a tilted disc, a rotating drive mechanism, and a water-spraying system. However, the design logic behind granulators for bio-organic fertilizer and those for ordinary organic fertilizer differs significantly. Attempting to use the same machine for both often results in the death of microbial strains, failure to form proper granules, or...
Why is granulation standard for organic fertilizer but unnecessary for blended fertilizer?
In fertilizer production, “granulation” is often considered a standard feature of production lines. However, a closer look reveals a distinction: blended fertilizer lines involve no granulation step from raw material to finished product, whereas organic fertilizer lines require powdered material to be rolled into granules. This difference is not merely a matter of equipment...
What should the tilt angle of a drum granulator be?
What should the tilt angle of a drum granulator be? 3.5° is a common benchmark value. In compound fertilizer, organic fertilizer, and NPK granulation production lines, the installation tilt angle of the drum granulator is usually controlled between 2° and 5°, with 3.5° considered the industry benchmark for general materials. This angle ensures that the material has sufficient residence time in...
