NPK compound fertilizer production combines chemical raw materials — urea, ammonium phosphate, potassium chloride or sulfate, fillers and additives — into uniform granules with a guaranteed nutrient formula. Accuracy starts at the batching stage, where load-cell weighing keeps each ingredient within tolerance.
Shunxin supplies NPK lines using rotary drum granulation with steam and ammonia dosing, or dry roller extrusion for moisture-sensitive formulas. Both routes include drying, cooling, screening, coating and packing, with dust collection at key transfer points.
