Double roller press granulators are efficient and energy-saving machines used to shape fertilizer. They are widely used in producing compound fertilizers, organic fertilizers, and speciality fertilizers. The granules they produce have unique physical and chemical properties that meet the diverse quality demands of modern agriculture.

1.High Granule Strength

The double roller press granulator presses powdered raw materials into granules under high pressure. This creates a dense internal structure and strong resistance to crushing. The granules hold up well during transport, storage, and mechanical spreading, minimizing breakage into powder. This ensures even application of the fertilizer.

2.Uniform and Regular Shape

The extruded granules are typically oblate or cylindrical. They have smooth edges and consistent size, giving them excellent flow properties. This makes them ideal for machine spreading (like with seeders or spreaders), boosting efficiency and reducing labor costs.

3.Stable Nutrient Release

The high-pressure compaction results in granules that dissolve relatively slowly. This allows for a more gradual release of nutrients, reducing losses from rain or irrigation. It improves fertilizer use efficiency and is particularly suitable for producing slow-release and controlled-release fertilizers.

4.Easy Storage

The granulation process generates almost no dust, reducing air pollution in the production area. The granules also have a smooth surface, making them less likely to absorb moisture and cake together during storage. This makes long-term storage easier.

In summary, fertilizer granules made by double roller press granulators offer significant advantages like high strength, controlled nutrient release, and easy storage. This process improves fertilizer quality while lowering production cost.
