Manufacturing Process Flow of Calcium Ammonium Nitrate

The production of Calcium Ammonium Nitrate CAN White granular agriculture is a sophisticated chemical engineering process, meticulously designed to ensure high purity, consistent granularity, and optimal nutrient balance. The typical process flow involves several critical stages, adhering to stringent quality control measures at each step.

1. Raw Material Preparation:
   • Nitric Acid Production: Ammonia (NH₃) is catalytically oxidized with air to produce nitric oxide, which is subsequently oxidized and absorbed in water to yield nitric acid (HNO₃). This is a foundational material.
   • Limestone/Dolomite Preparation: High-grade calcium carbonate (CaCO₃) or dolomite (a mixture of calcium and magnesium carbonates) is quarried, crushed, and then pulverized into a fine powder to maximize surface area for efficient reaction.
2. Neutralization & Reaction:
   • Ammonium Nitrate Formation: Nitric acid reacts with gaseous ammonia in a precisely controlled, highly exothermic neutralization reaction to form a concentrated ammonium nitrate (NH₄NO₃) solution.
   • Calcium/Magnesium Nitrate Formation: Simultaneously, a controlled portion of the nitric acid reacts with the finely ground limestone or dolomite to produce a calcium nitrate (Ca(NO₃)₂) and potentially magnesium nitrate (Mg(NO₃)₂) solution.
3. Mixing and Granulation:
   • The ammonium nitrate and calcium/magnesium nitrate solutions are combined in specific, pre-determined ratios. This blend is then fed into a specialized granulator (e.g., a pan granulator, rotary drum granulator, or fluid bed granulator).
   • Within the granulator, fine particles are agglomerated into larger, uniform granules. This is typically achieved by spraying the concentrated solution onto a bed of recycled fines and tumbling them to build up layers, often assisted by steam or a binder. The casting process ensures homogeneity.
4. Drying and Cooling:
   • The newly formed, wet granules are conveyed to a rotary dryer where hot air reduces the moisture content to below 0.5%, critical for preventing caking and ensuring product stability.
   • Following drying, the granules are rapidly cooled in a fluid bed cooler or rotary cooler to solidify them, prevent agglomeration, and prepare them for subsequent processing.
5. Screening and Coating:
   • Granules are passed through precision screens to classify them by size. Oversized and undersized particles are separated, with the latter often recycled back into the granulation stage, ensuring tight control over particle size distribution.
   • The properly sized granules are then coated with an anti-caking agent (e.g., a blend of mineral oil and amine) to improve flowability, reduce dust, and enhance storage stability. This coating also contributes to the corrosion resistance of the granules themselves.
6. Quality Control and Packaging:
   • Throughout the process and on the final product, continuous testing is conducted for nutrient content, moisture, particle size distribution, crushing strength, and chemical purity. These tests adhere to international standards such as ISO 9001 and often ANSI/ASABE for agricultural product specifications.
   • The finished, quality-assured product is then packaged into various formats, including 25kg, 50kg bags, or 1000kg bulk bags (FIBCs), or prepared for bulk vessel shipment, optimized for logistics and end-user requirements.

This meticulous manufacturing process ensures that the final product, Calcium Ammonium Nitrate CAN White granular agriculture, consistently meets stringent quality requirements. The target industries for this high-quality granular product predominantly include broad-acre cropping, horticulture, viticulture, fruit orchards, and pasture management. Products manufactured under such controlled conditions boast a typical service life of 2-3 years when stored correctly in cool, dry conditions, maintaining their physical and chemical properties and delivering consistent performance in typical application scenarios like energy saving for efficient crop growth and corrosion resistance to agricultural machinery.
