The NPK fertilizer production line is an automated production system specialized in producing compound fertilizers containing three main nutrients: nitrogen (N), phosphorus (P), and potassium (K). The design of this production line aims to efficiently and accurately mix various raw materials, and through processes such as granulation, drying, cooling, and screening, produce NPK fertilizer granules with uniform particle size, stable nutritional content, and easy storage and use.
