Why is there a standard for water in the
NPK fertilizer production?
First, the moisture content is not suitable for molding. Just like the mud, it is to pack and pack the particles with a moisture content of more than 35%. The only result is to become a group.
Second, the state's regulations on organic fertilizer production lines, so that the water content of our products cannot exceed 35%.
Third, the moisture content of the raw materials is too large, it is not suitable for pulverization, it is not suitable for molding, and it is not suitable for packaging.
Understand the problem of the moisture content of the compound fertilizer equipment, and strictly enforce it during operation to ensure the safe operation of the equipment.
Under normal circumstances, in all the fertilizer processing production process, the material is required to have a certain viscosity, some raw materials are loose after fermentation, and it is not easy to granulate, it is necessary to add some moisture or binder to increase the material. Viscosity. No matter what kind of compound fertilizer equipment is used, it needs to add water.
Some granulation processes in compound fertilizer production are granulated by agglomerating method, and water or binder is added during the granulation process to ensure that the materials can be granulated smoothly. The new compound fertilizer equipment adopts wet granulation, and the materials after fermentation can be directly granulated without the operation of other processes. It is produced by the non-drying normal temperature process and is suitable for granulation of materials with low viscosity or low water content.
If the moisture content of the material is too high during the process of NPK compound fertilizer production, some relatively dry materials may be added in an appropriate amount to neutralize the water content: if the water content is too low, water may be added in an appropriate amount to facilitate granulation. Under normal circumstances, in all the
fertilizer manufacturing process, the material is required to have a certain viscosity, some raw materials are loose after fermentation, and it is not easy to granulate, it is necessary to add some moisture or binder to increase the material. Viscosity. No matter what kind of compound fertilizer equipment is used, it needs to add water.
