Q 2: What Types of NPK Fertilizer Production Line Can you Choose?

In SX, there are three types of NPK fertilizer Manufacturing line for your choice.

jaw crusher for npk fertilizer
Raymond Mill System for powder chemical fertilizer
manure bagging for npk fertilizer

Powdery Chemical Fertilizer Production Line

When you want to make NPK fertilizer from raw ore, we recommend you choose to prepare it into powdery chemical fertilizer. Because it only needs equipment: Jaw crusher, Raymond mill, screener and packaging machine. If you plan to add liquid chemical materials like SSP fertilizer production, Add a fertilizer blender is enough.

NPK Fertilizer Blending System 

In this process, using chemical pellets as materials, only need three steps, you finish quality NPK fertilizer manufacturing. Batching, mixing and bagging. For this, we can offer you static batching machine, BB fertilizer mixer and automatic packaging scale and suitable conveyor.
