How to solve the problem of fertilizer caking?

The longer the fertilizer is placed, the easier it is to agglomerate. The shorter the time is, the less easy it is to agglomerate. In order to prevent caking, we should pay attention to the following aspects in the fertilizer production process.
1. Reasonably select raw materials. In the NPK fertilizer manufacturing process, select raw materials that are not easy to agglomerate, such as microelement foliar fertilizer. The raw materials are iron, copper, manganese, zinc, sulfate, boric acid and ammonium molybdate. The additives are mainly magnesium sulfate. The main materials are dry. When the air is not too wet, the fertilizer produced is not too agglomerated. The fertilizer and amino acid are mainly humic acid The fertilizer used as the main raw material is not easy to agglomerate. In addition, choose dry materials as much as possible.
2. Choose a suitable production time. For example, most of China belongs to the north temperate zone. The rainy season is mostly concentrated in June, July, August, and the time with higher temperature is also concentrated in this time. Therefore, the probability of fertilizer production in spring, late autumn, and winter is lower. This is because the air humidity is small and the temperature is not high, which is not conducive to agglomeration.
3. Add some anti caking agents in the organic fertilizer production process, such as talcum powder, humic acid and other powder which are not easy to caking materials, they play a role of bridge breaking in the middle. Some surfactants can also be added to prevent caking.
4. Reasonable packaging shall be adopted to prevent extrusion. Packaging materials shall mainly prevent moisture absorption and air permeability. Excessive extrusion shall be prevented during transportation and storage, and caking shall also be prevented effectively.
5. The organic fertilizer granulator can prevent caking. Due to the small contact area between particles, it is not easy to crystallize and caking. Therefore, if conditions permit, granulation of fertilizer is a good way to prevent rapid formation.
