The core technical characteristics of a fertilizer roller press granulator focus on three key areas: binder-free granulation, high-strength granule production, and adaptability to multiple raw material systems.  Specifically:

1. Dry granulation, no additional binder required

The machine directly compresses dry powdered organic fertilizers, NPK compound fertilizers, and other materials into granules using mechanical extrusion force, eliminating the need for binder procurement and preparation. This reduces production costs and avoids binder residue affecting fertilizer purity and effectiveness.

2. High granule strength and stable molding quality

The extrusion force is controllable and evenly distributed, resulting in high-density granules that are not easily broken. This meets the needs of subsequent packaging, transportation, and field application of blended fertilizers, reducing material loss during the production process.

3. Wide raw material compatibility and high flexibility

It is compatible with organic fertilizers, NPK compound fertilizers, and functional blended fertilizer raw materials with different compositions. By adjusting parameters such as extrusion force and rotation speed, it can adapt to the physical characteristics of different raw materials without requiring extensive equipment modifications.

4. Short process flow and relatively low energy consumption

It eliminates complex processes such as raw material pre-wetting and drying, directly converting "dry powder → granules," shortening the process chain of the entire roller press granulator production line and reducing energy consumption and time costs associated with drying.
