In the field of fertilizer production, high moisture content of the material is a thorny problem that may affect the normal operation of the fertilizer granulator. We can ensure its smooth operation through the following methods.
- Drying pretreatment
Special drying equipment, such as drum dryers, can be used to dry materials with too high moisture content. By controlling parameters such as drying temperature, time and wind speed, the moisture content of the material can be reduced to a range suitable for the operation of the granulator. For example, for some organic fertilizer materials, the temperature is controlled between 60-80°C, and the moisture content can be effectively reduced after drying for a period of time.
- Mixing adjustment
The moisture content of different raw materials varies greatly, and the overall moisture content can be adjusted by reasonable matching. For example, the moisture content of livestock and poultry manure is usually about 70%, while the moisture content of straw may be only 15%-20%. Mixing the two in a certain proportion can make the moisture content of the mixed raw materials close to the ideal range.
- Adjust the parameters of the fertilizer granulator
If the material cannot be fully dried, the granulator needs to be adjusted appropriately. Reduce the speed of the granulator to reduce the frequency of squeezing and friction of the material in the machine. Avoid material adhesion and blockage caused by excessive moisture. At the same time, appropriately increase the ventilation volume in the granulator to help dissipate excess moisture.
- Improve ventilation
Enhance the ventilation conditions around the granulator. Good ventilation helps to dissipate moisture in the material and reduce humidity in the machine. Prevent operational failures caused by moisture accumulation.
- Additive use
Consider adding desiccant or lubricant. Desiccant can absorb part of the moisture, and lubricant can reduce the friction between materials. Make the movement of high-water content materials in the granulator smoother.
In the process of fertilizer production, in the face of excessive moisture content of the material, the comprehensive use of the above methods can ensure the normal operation of the fertilizer granulator. Thereby ensuring the smooth progress of fertilizer production and improving production efficiency and product quality.
