What Raw Materials Are Suitable for NPK Fertilizer Dry Extrusion Granulation?

ou may wonder which raw materials are ideal for double roller granulator to make NPK fertilizer pellets. Typically, you can produce common nitrogen fertilizer from urea, ammonium sulfate, ammonium nitrate, etc. Also, in the NPK dry granulation process, you need to consider these NPK compounds’ solubility, hygroscopicity, and thermal stability. For example, urea is prone to moisture absorption and requires add less water during the extrusion granulation process.

In addition, you can use superphosphate, MAP, DAP powder to make phosphate fertilizer granules. These materials are usually in powder form with poor flowability. So, our double roller pelletizer compacts such powdery substances to form NPK particles without adding liquid binders. Moreover, you ought to adjust the particle density and strength by adjusting the pressure and roller spacing.

Besides, if you want to produce potassium fertilizer, you can use potassium chloride or potassium sulfate, which have good stability, plasticity and low moisture absorption. Consequently, you can get final NPK fertilizer pellets with high strength and uniform size by adding more water during the compound fertilizer granulation system.
