The production process of Di-ammonium phosphate involves reacting phosphoric acid with ammonia, followed by cooling, grinding and sieving. It can be obtained by the slurry method or the traditional method, in which the slurry method directly uses dilute phosphoric acid produced by the wet method as raw material, ammoniates it in a neutralization tank or a rapid ammoniation evaporator, and then evaporates and concentrates the neutralized slurry to reduce the water content, and then makes Di-ammonium phosphate in granular form by spraying slurry pelletizing and drying, or makes powdered Di-ammonium phosphate by spray drying and fluidized pelletizing and drying.

Production Process

Raw Material Preparation: Phosphoric acid and ammonia are the primary raw materials.
Neutralization: Phosphoric acid is reacted with ammonia to form a slurry of DAP.
Granulation: The slurry is granulated to form uniform DAP particles.
Drying and Cooling: The granules are dried and cooled to achieve the desired moisture content.
Screening and Packaging: The granules are screened for size consistency, then packaged for distribution.
