As a high-concentration phosphate fertilizer, Diammonium Phosphate (DAP) presents key processing challenges: it is prone to moisture absorption and caking, and its nutrients are susceptible to loss. Furthermore, since it is frequently blended with other raw materials to produce compound fertilizers, the demands placed on the adaptability of the granulation equipment are exceptionally high. Thanks to its specialized process design, the rotary drum granulator is perfectly tailored to meet the specific processing requirements of Diammonium Phosphate.

The rotary drum granulator employs a controllable wet granulation process that precisely regulates water distribution ratios. This approach fundamentally resolves the persistent problem of DAP absorbing moisture and caking, prevents nutrient loss caused by contact with water, and simultaneously maximizes the preservation of the fertilizer’s active efficacy. The lifting and tumbling action of the drum’s internal flights ensures that raw materials are uniformly formed into granules; these granules exhibit high density and strong compressive strength, making them resistant to breakage during transport and storage, as well as impervious to moisture absorption and caking.

This equipment boasts exceptional blending compatibility, allowing it to flexibly accommodate the granulation of DAP mixed with nitrogen, potassium, and various macro- and micro-elements. It eliminates the need for frequent shutdowns and recalibrations, thereby significantly boosting production efficiency for multi-formula compound fertilizers. Moreover, the unit operates with high stability and low energy consumption; equipped with a wear-resistant inner lining to withstand the mild corrosiveness of DAP, it offers ease of maintenance and a low failure rate.

In summary, the rotary drum granulator precisely aligns with the processing characteristics of Diammonium Phosphate. From moisture control and anti-caking measures to multi-component blending and large-scale operations, it comprehensively fulfills the production requirements for both DAP and compound fertilizers, making it the ideal equipment for high-standard Diammonium Phosphate processing.
