On January 20, 2026, at the Indonesian compound fertilizer production line site, technicians were performing leveling and pipeline connection on the drum granulator and extrusion granulator after their placement. This is a customized compound fertilizer production line delivered by our company to an Indonesian client, employing a dual-line parallel design of “drum granulation + extrusion...

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...

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...

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...

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? 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...

When selecting a fertilizer production line, there is an easily overlooked engineering fact: although they process the same NPK raw materials, the blending process and the extrusion granulation process address two completely different physical challenges. NPK blending lines deal with pre-formed granules; their task is to achieve precise formulation without altering the physical form of the raw...

When selecting organic fertilizer granulation equipment, a crucial engineering fact is often overlooked: even when processing the same composted livestock manure, different process routes yield granules that differ vastly in density, strength, and the subsequent drying load. Disc granulators, double-roller press granulators, and the new “two-in-one” organic fertilizer granulators represent three...

High-tower granulation technology represents a major technological revolution in compound fertilizer production. Its core lies in “melt-to-granulation”—high-temperature molten fertilizer slurry is sprayed from the top of a tower, cooling and solidifying during its free fall to directly form rounded granules. This technology bypasses the multiple steps of traditional granulation...
