Three reasons for drying fertilizer after granulating

The process of granular organic fertilizer production line includes fermentation, grinding and mixing, granulation, drying and other process stages. From the surface, since the particles are formed, is it not necessary to dry them? In fact, the drying of granular products is very important. So why do we need to dry after granulation in granular organic fertilizer production line?

1. Reduce the moisture content of granular organic fertilizer

As we all know, the water content of organic fertilizer raw materials is relatively high. Although the water content of materials has been reduced in the process of early fermentation, grinding, mixing and transportation, it is only reduced to the water content required for processing granules. The moisture content of the processed particles is between 20% and 40% according to the characteristics of the materials. In order to make the organic fertilizer products easier to store and transport, drying is necessary. Therefore, the process of granular organic fertilizer production line can not do without dryer and cooler.

2. Increase the strength of organic fertilizer particles

In the process of commercialization of organic fertilizer, the particles with low strength are disadvantageous to commercial packaging and transportation. In the process of transportation, the damage rate of particles increases due to low strength. Therefore, in order to meet the needs of commercialization, the granular organic fertilizer production line also needs to be dried after treatment.

3. Extend the storage life of particles

As a commercial granular organic fertilizer, it takes time from packaging to application, which requires the preservation of organic fertilizer as long as possible without reducing the nutrients of fertilizer. The loss of nutrients is often due to volatilization and particle strength reduction, so drying can effectively extend the storage and transportation period of granules. Therefore, the drying process of granular organic fertilizer production line is also beneficial to extend the storage life of granules.
