Finished Product Options



Produce various bulk blended fertilizers according to crop nutrient requirements, regional agricultural needs, and market demand.
Production Process
Granular fertilizer materials are fed into the batching system and accurately weighed according to the required formulation. The materials are then conveyed to the BB fertilizer mixer for uniform blending before being discharged into the automatic packaging system.

FAQ
BB fertilizer is produced by physically blending different fertilizer granules, while conventional granular compound fertilizers are manufactured through processes such as granulation. BB fertilizer production generally requires fewer processing steps.
Yes, but materials with similar particle sizes and densities are recommended to minimize segregation and maintain consistent fertilizer quality. Screening may be required for materials with significant size differences.
Yes. The automatic batching system allows operators to adjust material proportions to produce different NPK formulations according to crop and market requirements.
Yes. Micronutrients can be incorporated using suitable granular materials or specially designed addition systems. The feeding method depends on the required dosage and material characteristics.
No. Some fertilizers may be chemically or physically incompatible. Raw material compatibility must be checked to prevent caking, moisture absorption, and other quality problems.
Uniform mixing depends on accurate batching, suitable raw materials, proper mixing time, and equipment design. Mixing parameters can be adjusted according to material characteristics.
