When selecting a fertilizer granulator, material characteristics play a crucial role. Different materials have varying physical and chemical properties that directly affect equipment choice and performance. Here's how to pick the right granulator based on material traits:

1. Material Stickiness

For sticky materials like humus-rich organic matter, disc granulators work best. The rotating disc rolls and presses materials into balls. Sticky stuff bonds well during this tumbling process. Disc granulators offer flexible operation for these materials and cost less.

2. Material Hardness and Fiber Content  

Tough or fibrous materials (like wood fiber-rich organics) need double roller press granulators. These machines crush materials between rollers to form hard, uniform pellets. The resulting grains hold their shape well during handling and storage.

3. Material Moisture  

For wet materials, consider granulators with drying functions. Rotary drum granulators help here - their rotating action lets materials dry gradually while forming.

4. Grain Shape and Size Needs

Different machines make different shapes. Disc granulators create adjustable round pellets. Double roller press granulators produce flat or pillow-shaped grains. Choose based on your market requirements.

The key is understanding your material's stickiness, hardness, fiber content, and moisture. Match these traits with each granulator's working principle, production capacity, and costs to find your perfect fit.
