Advantages of dry granulation

Common organic fertilizer granulators suitable for dry granulation mainly include double roller press granulator and flat die granulator. As a later developed but widely used granulation technology, the dry granulation process has many advantages. Dry granulation generally does not need to add additives, and the dry powder can be directly made into granules to increase the bulk density, improve the appearance and fluidity, and facilitate storage and transportation. Compared with wet granulation, dry granulation can save energy, reduce pollution and improve overall production efficiency.

The dry granulation machine requires little space, but its production capacity will never shrink with the size reduction. Manufacturers can use some space to install more dry granulators, which means higher overall production. The dry granulation process can be used in different production lines, such as NPK  fertilizer production line, etc. Dry granulator can guarantee the high quality of its products. Granular products have uniform particle size and higher strength than other granulator products.

Granular products made by dry granulation are more soluble because they contain less water. Dry granulation is a cost-effective granulation method favored by many manufacturers.
