Machines Used in Fertilizer Granulation: Classification and Applications in 2026

Granulation is a pivotal process in fertilizer production, transforming fine powders into granular forms that enhance handling, storage, and uniform application. In 2026, the machinery employed for NPK and organic fertilizer granulation is primarily categorized based on the production method: Wet Granulation and Dry Granulation. The selection of appropriate equipment is determined by key factors such as production scale, raw material moisture content, and budget constraints. Additionally, a complete granulation line relies on a suite of support machinery to ensure product quality and production efficiency. Understanding these granulation machines and their functions is essential for optimizing fertilizer manufacturing processes.

Wet granulation machines, which utilize liquid binders or steam to aggregate powder into granules, are widely used in both NPK and organic fertilizer production. The Rotary Drum Granulator stands as the industry standard for large-scale NPK production, capable of handling output rates up to 30 tons per hour (t/h). In this machine, raw materials tumble within a rotating cylinder, forming dense, spherical granules through either chemical reactions between components or the addition of liquid binders. Its high capacity and stable performance make it indispensable for large commercial fertilizer plants.
