Compound fertilizer liquid ammonia dilute sulfuric acid granulation production line

The compound fertilizer amino acid granulation production line is a piece of equipment used for manufacturing compound fertilizers. Its core principle is to conduct an ammoniaization reaction in a specific reaction device by combining gaseous ammonia (NH₃) with acidic raw materials such as sulfuric acid and phosphoric acid. This reaction generates nitrogen carriers such as ammonium sulfate and mono-phosphate ammonium. At the same time, raw materials such as urea, potassium chloride/sulfate potassium, phosphate rock powder, and trace elements (such as calcium, magnesium, sulfur, etc.) are mixed according to the formula ratio. The heat released during the ammoniaization reaction and the viscosity of the materials are utilized in the granulation equipment to form uniform particles. Then, through subsequent processes such as drying, cooling, screening, coating, and packaging, stable nutrient content and high particle strength compound fertilizers are produced.
The complete production line usually includes raw material pre-treatment units (crushing, screening, metering), amino acid reaction units (ammoniaization reactors, acid mist absorption devices), granulation units (turbine granulators / disc granulators), drying and cooling units (rotary dryers, cooling machines), finished product processing units (screening, coating, metering packaging), and environmental protection auxiliary units (tail gas purification, wastewater recycling system). The coordinated operation of each unit enables continuous and automated production.
