Compound fertilizer extrusion granulation production line

The compound fertilizer extrusion granulation production line is a complete set of specialized equipment system used for industrial production of compound fertilizers. Its core function is to convert basic fertilizer raw materials (such as nitrogen, phosphorus, potassium, etc., which can be combined with trace elements and fillers, etc.) through a continuous process centered on “extrusion granulation” into stable physical properties and evenly distributed granular compound fertilizer products, to meet the requirements of agricultural fertilization for fertilizer storage, transportation, ease of application, and nutrient release. This production line is widely used in the production of compound fertilizers, organic-inorganic compound fertilizers, and biological organic fertilizers, and can be adapted to various raw material formulas (such as urea, monoammonium phosphate, potassium chloride, etc., mixed systems), supporting large-scale production needs of different capacities (usually from 1 to 20 million tons per year).
This production line is not a single equipment, but a continuous production process composed of raw material pre-treatment (such as crushing, screening, mixing), extrusion granulation (the core equipment is usually a pair-roller extrusion granulator or flat mold extrusion granulator), post-treatment (including particle drying, cooling, screening and classification, coating to prevent agglomeration, etc.) and auxiliary systems (such as conveying, dust removal, control system).
The characteristics of the compound fertilizer extrusion granulation production line
Strong adaptability to raw materials, wide application range; stable product quality, excellent particle characteristics (high particle strength, good nutrient uniformity, regular particle shape); low energy consumption, energy-saving and environmentally friendly (low moisture extrusion, less waste gas and wastewater); compact process, flexible operation; simple equipment structure, low maintenance cost.
