NPK Compound Fertilizer Production Line with Adjustable NPK Ratio 20%-48% and Rotary Drum Steam Granulation for Precision Batching ±0.5%

This NPK Compound Fertilizer Production Line is engineered to produce compound fertilizers with total nutrient content ranging from 20% to 48%, fully adjustable based on customer formulation requirements. The rotary drum granulation system ensures precise nutrient distribution and consistent quality across every batch.

• Adjustable NPK Ratio: Flexible formulation system supports N-P₂O₅-K₂O ratios from 15-15-15 to 28-12-8 and beyond, programmable via the batching control system
• High Total Nutrient: Achieve 20%-48% total nutrient content with homogeneous distribution verified by laboratory sampling at each production shift
• Precision Batching: Electronic weighing system with ±0.5% accuracy for urea, ammonium phosphate, potassium chloride, and micro-nutrient additives
• Trace Element Addition: Integrated dosing system for secondary nutrients (Ca, Mg, S) and micronutrients (Zn, B, Mn, Fe, Cu, Mo)
• Quality Laboratory: Complete NPK testing protocol including Kjeldahl nitrogen analysis, spectrophotometric phosphorus, and flame photometric potassium testing
