A rotary drum dryer can help you reduce material moisture and improve granule quality. But how to choose the right dryer capacity and heat source? Whether you operate a 1–5 t/h drying line or a 15–20 t/h fertilizer production plant, selecting the proper drying system is critical for efficiency and profitability. From natural gas and biomass to biogas and waste heat recovery, YUSHUNXIN fertilizer drying solutions can help you lower energy costs while maintaining stable, continuous fertilizer granules production.
How does a Rotary Drum Dryer work?
The working principle of a rotary dryer is straightforward. Wet material first enters the drying drum from the feed end. As the drum rotates slowly, the internal lifting flights continuously lift and scatter the material, allowing it to make full contact with the hot air inside the drum. During this process, moisture gradually evaporates, and the material moves towards the discharge end. Finally, the dried material leaves the drum through the discharge device at the lower end, completing the drying process.
Why Is a Fertilizer Dryer Needed in a Fertilizer production Line?
After learning how a rotary drum dryer works, you may wonder about its role. Why does a fertilizer granulation line need a dryer? What problems may occur without a drying process? In fact, a fertilizer dryer is an essential machine in wet granulation lines, both before and after granulation.
Top 4 Rotary Drum Dryers for 1–20 t/h Fertilizer Drying Lines in 2026
The role of a dryer in a wet granulation line is clear. However, you may still wonder which dryer is the right choice for your production capacity. Our rotary drum dryers are designed for continuous fertilizer production. They are available in different models. Each model can meet different capacity requirements and production needs.
SXHG-1212 for 1-5 t/h fertilizer drying line
If your fertilizer business is in its early stages and you require a cost-effective, low-capacity dryer, the SXHG-1212 is an ideal choice. It features a 7.5 kW motor and a ZQ350 gearbox, operates with an inlet temperature of at least 300°C, has an installation inclination of 3°–5°, and a drum rotation speed of 6 rpm.
SXHG-1616 for 5-10 t/h fertilizer drying line
SXHG-2020 for 10-15 t/h fertilizer drying line
SXHG-2424 for 15-20 t/h fertilizer drying line
To meet the needs of large-scale fertilizer production, YUSHUNXIN has developed the SXHG-2424 rotary drum dryer. The dryer is equipped with a 55 kW motor. It operates with an inlet temperature of at least 300°C. The installation inclination is 3°–5°. The drum rotation speed reaches 5.2 rpm. With these features, the SXHG-2424 is suitable for large-scale and continuous drying operations.
How to Choose a Heat Source for a Fertilizer Dryer?
You may worry that higher fertiliser drying capacity will lead to higher fuel consumption and operating costs. Actually, the drum is insulated with thickened rock wool to reduce surface heat loss during continuous operation. In addition, the counter-flow heat exchange design improves thermal efficiency by allowing hot air and fertilizer materials to contact inside the drum. Under suitable operating conditions, this configuration can reduce fuel consumption and lower long-term drying costs. So, are there energy-efficient heat sources that can reduce drying costs while maintaining stable dryer performance? The answer is yes, and we will offer four practical solutions.
Choosing the right fertilizer dryer can make your production line more stable, efficient, and cost-effective. Whether you need to dry compost, manure, organic fertilizer, or NPK granules, YUSHUNXIN will help you design a practical fertilizer drying solution based on your capacity, material moisture, and final product requirements.
