Fertilizer production equipment info

The NPK fertilizer granulator is the core equipment in the production of compound fertilizer s; its operational stability directly determines product quality and production efficiency. Due to the complex composition and corrosive nature of NPK raw materials—combined with the equipment's constant operation under heavy loads—various faults occur frequently. These issues not only disrupt production continuity but may also increase raw material wastage and maintenance costs. Drawing upon practical production experience, the following analysis outlines the most common types of granulator faults and their primary causes, serving as a reference for equipment maintenance and troubleshooting. Poor granule formation is the most frequent fault, manifesting as loose, brittle, or unevenly sized granules with rough surfaces—or, in severe cases, a complete failure of the material to agglomerate into granules. There are three primary causes for this: First, an imbalance in the raw material's ...
