How to Choose a Granulator for an NPK Production Line: Comparison of Disc / Double Roller / Drum Granulators
In the construction of an NPK compound fertilizer production line, the selection of the granulator is one of the most critical decisions. A proper selection results in high production line efficiency and stable product quality; a poor selection can lead to low forming rate, high energy consumption, and frequent downtime. Faced with the three mainstream models—disc granulators, double roller extrusion granulators, and drum granulators—enterprises need to follow the core principles of "raw material suitability, capacity matching, and product shaping" to make a scientific choice.
