BB fertilizer (Bulk Blended Fertilizer) is a type of compound fertilizer produced by dry blending granular raw materials containing nitrogen, phosphorus, and potassium. The production line offers a flexible and efficient solution for manufacturing customized NPK fertilizers tailored to different soil types and crop requirements.

The process is fully enclosed. Raw materials from bulk bins are precisely weighed by automated feeders, mixed homogeneously, and then directly transferred to the automated weighing and bagging system, forming a continuous production line.

• Formula Flexibility: Easily adjust NPK ratios and add micronutrients/amendments
• Automated Operation: Centralized PLC control ensures accuracy and reduces labor
• High Throughput: Designed for 10-30 t/h capacity, scalable for large-scale output
• Quality Consistency: Uniform blending technology guarantees balanced nutrient distribution
• Low Operating Costs: Energy-saving design with minimal maintenance requirements
