Compound fertilizer liquid ammonia dilute sulfuric acid granulation production line Core Definition & Purpose

Compound fertilizer liquid ammonia dilute sulfuric acid granulation production line Key Process Flow

1. Neutralization Reaction: Liquid ammonia and dilute sulfuric acid react in a reactor to generate ammonium sulfate slurry (or crystals), releasing heat to provide energy for subsequent processes.
2. Raw Material Mixing: The ammonium sulfate product is mixed with phosphorus, potassium, and other nutrient additives (such as trace elements) in a certain proportion to ensure the nutrient content meets the compound fertilizer standard.
3. Granulation: The mixed material is sent to granulation equipment (such as a drum granulator, disc granulator) to form wet granules. The granulation process often relies on the adhesion of the material itself or the addition of a small amount of binder.
4. Drying & Cooling: Wet granules are dried by a dryer (using hot air) to reduce moisture, then cooled to room temperature by a cooler to avoid caking.
5. Screening & Returning: The cooled granules are sieved. Qualified granular products are packaged as finished products, while unqualified particles (too large or too small) are crushed and returned to the granulation process for reuse.
6. Dust & Wastewater Treatment: Equipped with dust collectors and wastewater treatment equipment to meet environmental protection requirements during production.

Compound fertilizer liquid ammonia dilute sulfuric acid granulation production line Core Characteristics

• Raw Material Advantages: Liquid ammonia and dilute sulfuric acid are low-cost and widely available, reducing the production cost of compound fertilizers.
• Product Features: The produced granular compound fertilizers have uniform particle size, high nutrient content, and good fluidity, which are convenient for storage, transportation, and mechanical fertilization.
• Applicability: Suitable for large-scale industrial production, and can flexibly adjust the N-P-K ratio to produce compound fertilizers for different crops (such as rice, wheat, vegetables) and soil types.
