Rotary Drum Granulator: The "Shaping Master" of NPK Granules?
In the NPK compound fertilizer production process, the rotary drum granulator acts like a skilled "shaping master," transforming evenly mixed nitrogen, phosphorus, and potassium raw materials into granules of uniform size and moderate hardness. Once the mixed powdered ingredients enter the inclined drum, the slow rotation of the drum causes them to tumble and agglomerate. With the addition of an appropriate amount of binder, the loose powder gradually binds into spheres, ultimately forming granules with a diameter of 2-4 mm. These granules not only facilitate fertilizer application but also
