Introduction of NPK Fertilizer Production Line
Complete urea-based compound fertilizer granules equipments line is widely used to manufacture urea compound fertilizers with different concentrations and types.And its capacity ranges from 10,000 tons to 300,000 tons per year.

Working Process Of NPK Compound Fertilizer Making Production Line
The equipment adopts a sliding extrusion die design. Raw materials pass through double rollers, enter the scattering chamber, and are formed into granules. A customized sieve is mounted at the bottom to separate qualified granules, while the remaining material is returned to the mixer for re-granulation.

Raw Material For NPK Compound Fertilizer Making Production Line
A compound fertilizer contains two or all three primary plant nutrients — Nitrogen (N), Phosphorus (P), and Potassium (K) — as well as essential microelements such as Boron (B), Manganese (Mn), Copper (Cu), Zinc (Zn), and Molybdenum (Mo). This versatile fertilizer can be manufactured using both powdered and granular raw materials, offering flexible adaptation to various formulations and production requirements.
