The flat die granulator, a core piece of equipment in fertilizer processing, handles a wide range of fertilizer granulation needs thanks to its unique structural strengths and processing capabilities.

1.Organic Fertilizers
Livestock manure fertilizers: Chicken/pig/cow manure-based organic fertilizer
Handling strength: Flat die granulator effectively tackles the challenge of forming high-moisture materials (30-40% water content).
Processing note: Requires adding 10-15% auxiliary materials to adjust moisture.
Agricultural waste fertilizers: Straw/fermented residue/food waste fertilizer
Special design: Equipped with reinforced cutters to shred fibrous materials.
Granulation rate: Reaches 85-92%.

2.Inorganic Compound Fertilizers
General-purpose compound fertilizers: NPK compound fertilizers (like 15-15-15)
Output capacity: 1-5 tons per hour (varies by model).
Pellet size: Adjustable range of 2-8mm.
Specialty formula fertilizers: Fruit tree or vegetable-specific fertilizers
Formula advantage: Allows adding medium or trace elements without damaging nutrients.
Temperature control: Granulation process stays below 50℃.

3.Bio-Organic Fertilizers
Microbial agent compound fertilizers: Functional microbe content ≥200 million/g
Process feature: Low-temperature granulation protects microbial activity.
Typical formula: Organic matter + functional microbes + humic acid.

4.Specialty Functional Fertilizers
Slow-release fertilizers
Coating compatibility: Works with resin or sulfur coatings.
Release control: Initial dissolution rate below 15%.
Organic-inorganic compound fertilizers
Blending flexibility: Handles 30-70% organic matter content.
Uniformity assurance: 3D mixing granulation technology.

The flat die granulator’s versatility makes it ideal for fertilizer producers upgrading their operations. By simply changing molds and adjusting parameters, a single unit can produce multiple fertilizer types, significantly lowering investment costs.
