Take a focused look at the specifications and what they mean in practice with this rotary drum granulation production line walkthrough. We demonstrate how the ammoniation granulator, steam injection, and drying-cooling system work together to produce uniform NPK granules. See the UHMW-PE lining, drum inclination settings, and material flow inside the drum, and learn how high-concentration compound fertilizers achieve a granulation rate above 90% with fewer fines. Ideal for B2B fertilizer manufacturers evaluating equipment.
