Compound fertilizer high tower granulation production line

The high tower granulation production line for compound fertilizers is a specialized industrial equipment and process integration system that focuses on continuous and large-scale production of granular compound fertilizers. Its core principle is to utilize the vertical space advantage of the high tower (typically 50-100 meters in height), and through the spray granulation device at the top of the tower, the nitrogen, phosphorus, potassium and trace element compound fertilizer slurry that has been heated and uniformly mixed is sprayed down. During the falling process of the slurry, it fully contacts the upward-flowing low-temperature air in the tower, completing heat transfer and cooling, and gradually solidifying into spherical or nearly spherical particles. Finally, through the subsequent processes of conveying, screening, cooling, coating and other procedures, it forms finished compound fertilizers that meet quality standards. This production line usually includes raw material pre-treatment unit (crushing, batching, mixing), slurry melting unit (heating, stirring, homogenization), high tower granulation unit (spray device, tower body, air flow regulation), particle post-treatment unit (screening, impurity removal, cooling, anti-caking coating), and automatic control system (parameter monitoring, process linkage, quality traceability). The units operate collaboratively to achieve continuous and standardized production of compound fertilizers. Its core advantages lie in that the granulation process does not require additional adhesives, and the finished particles have high roundness, high strength, uniform nutrient distribution, wide adaptability to raw materials, good environmental performance, high automation level, relatively small floor area, and is suitable for the large-scale production of high-concentration, multi-functional compound fertilizers.
