Which granulation method is best?

Comparison of Mainstream Granulation Technologies
Rotary drum granulation dominates large-scale NPK fertilizer production with its high capacity and stable particle quality. This type of fertilizer production machine is particularly suitable for producing balanced fertilizers like 20-20-20 formulations, ensuring particle uniformity and nutrient distribution consistency. However, this method is relatively sensitive to raw material moisture and has higher energy consumption.

Disc granulation, with its simple structure and low investment cost, is widely popular in small and medium-sized fertilizer plants. This NPK fertilizer granulator offers flexible operation and excellent particle roundness, making it particularly suitable for products with small batch sizes or frequent formulation adjustments. For companies new to the industry, this represents a relatively safe choice.

Special Considerations for Organic Fertilizer Production
In the organic fertilizer production sector, the choice of organic fertilizer granulator is more diverse. Extrusion granulation has become the preferred method for organic fertilizer production as it requires no binder addition and produces high-strength granules. This method effectively handles viscous raw materials and produces high-quality granules that meet organic agriculture standards.
