MAP (Monoammonium Phosphate) fertilizer is a high-concentration, highly water-soluble binary fertilizer containing nitrogen and phosphorus, serving as a core raw material for compound and blended fertilizers. A MAP fertilizer production line is an integrated chemical processing system designed for the industrial-scale mass production of both powdered and granular MAP.

Utilizing phosphoric acid and liquid ammonia as primary raw materials, the production line achieves material conversion through precise proportioning and temperature-controlled reactions. In the initial stages, specialized equipment purifies, meters, and conveys raw materials at a steady rate, strictly controlling the acid-base balance and reaction temperature to prevent impurity formation caused by improper ratios. The line features dedicated reaction equipment that facilitates the neutralization of raw materials into MAP slurry; the heat generated by the reaction drives self-evaporative dehydration, effectively reducing drying energy consumption and offering significant advantages in terms of energy efficiency, continuous operation, and stability.

The production line offers flexibility in product form to meet diverse market demands. The slurry can be processed via spray drying into powdered MAP—suitable for water-soluble fertilizer production—or fed into granulation equipment to form granular MAP, which meets the needs of direct field application. The formed product undergoes drying, cooling, and screening; off-specification materials are recycled back into the process, significantly enhancing raw material utilization rates.

Additionally, the MAP fertilizer production line is equipped with comprehensive testing and environmental protection systems that monitor key indicators—such as nutrient content and moisture levels—in real-time, ensuring consistent product quality. Thanks to its flexible production capabilities and stable output quality, the line can produce various specifications of MAP, including agricultural-grade and water-soluble grades, catering to a wide range of agricultural cultivation and fertilizer processing applications.
