How to Dry Granular Fertilizer?

When it comes to producing high-quality fertilizer granules, proper drying is crucial. One effective and widely used method for drying fertilizer granules is through a dryer. Besides, the granular fertilizer dryer is a cylindrical vessel equipped with rotating drums where fertilizer granules are exposed to hot air to remove moisture effectively.

Steps to Efficiently Dry Fertilizer Granules with A Drum Dryer


Step 1: Choosing the right dryer for drying fertilizer pellets

Select a drum dryer that suits your specific fertilizer production requirements. Consider factors such as drum size, material compatibility, energy efficiency, and control features. This will ensure optimal performance and efficient drying. You can choose SX granular fertilizer dryer, with uniform drying effect, versatility of raw materials and energy efficiency.


Step 2: Preparing the granules

Before drying, ensure that the fertilizer granules are properly sized and uniformly shaped. This will facilitate even drying and prevent clumping or degradation during the drying process. You may need a granulator to finished this step. Thus, you can refer to Shunxin’s fertilizer granulator, after all, is China’s leading fertilizer machine manufacturer.


Step 3: Loading the drum dryer

Carefully load the fertilizer granules into the drum dryer, taking care not to overload it. An evenly spread layer of granules allows for efficient heat transfer and airflow within the drum, promoting effective drying.

Step 4: Applying Heat

Start the drum dryer and set the desired temperature for drying the fertilizer granules. The heat source can be natural gas, diesel oil, or biofuel, depending on the design of your drum dryer. Maintain the recommended drying temperature to prevent over-drying or under-drying.


Step 5: Monitoring the Drying Process

Regularly monitor the drum dryer and observe the progress of drying. Adjust the drum rotation speed, air velocity, and temperature as needed to optimize the drying efficiency. Use sensors to measure moisture levels and adjust drying time accordingly.

Step 6: Ensuring Proper Airflow

Proper airflow is crucial for drying fertilizer granules uniformly. The drum dryer’s design should facilitate adequate air circulation within the drum to evenly distribute heat and remove moisture. Regularly check and clean air inlets and outlets to avoid blockages and maintain optimal airflow.


Step 7: Cool Down and Packaging

After the drying process is complete, allow the fertilizer granules to cool down before packaging. This step is essential to prevent moisture absorption, heat damage and clumping, ensuring the granules are ready for storage or packaging. Utilize cooling systems like rotary drum coolers to achieve efficient cooling.
