In the wet granulation method of fertilizer production, according to type of wet granulation equipment you use, the moisture content of the granules can be adjusted during different stages of the process to achieve the desired properties. Here are a few ways of fertilizer making moisture content changing:
Mixing Stage
During the initial mixing of the raw materials, it is essential to achieve a uniform distribution of moisture throughout the organic waste or npk mixture. The moisture content can be adjusted by adding water or a liquid binder gradually while mixing the components. The amount of moisture added will depend on the specific requirements of the fertilizer formulation and the desired moisture content of the final granules.
Granulation Stage
The addition of a liquid binder or solution during wet fertilizer granulation helps agglomerate the particles and form granules. The moisture content can be controlled by adjusting the amount of binder added. A higher amount of liquid binder will increase the moisture content, resulting in softer and more easily deformable fertilizer granules. Conversely, a lower amount of liquid binder will result in dry granules.
Generally, in wet granulation process, the required water content is 20%-45%. in order to make moisture content easier, SX design spray device for disc wet granulator and rotary drum wet pelletizer. Go here for more details.
Drying Stage
After the granulation process, the moist granules need to be dried to remove excess moisture and improve stability. The drying step plays a crucial role in controlling the final moisture content of the granules. The drying conditions, such as temperature and airflow, can be adjusted to achieve the desired moisture level. Increasing the drying temperature and airflow will accelerate the drying process and reduce the moisture content of the granules.
It’s important to note that the moisture content of the granules should be optimized for the specific fertilizer formulation and the intended application. Excessive moisture content can lead to problems such as caking, reduced shelf life, and difficulties in handling and storage. On the other hand, insufficient moisture content can result in weak or friable granules that may break during handling or application. Therefore, manufacturers carefully control and monitor the moisture content throughout the wet granulation process to ensure the production of high-quality fertilizer granules.
