The fertilizer granule urea-formaldehyde coating production line is a complete production system that focuses on urea-formaldehyde (UF) slow-release fertilizer granules as the core processing object. Through a continuous and automated equipment combination and process flow, it realizes the “enhancement of coating function” for urea-formaldehyde fertilizer granules. Its core purpose is to form a uniform and dense functional coating layer on the surface of urea-formaldehyde granules (common materials include modified resins, polymer emulsions, inorganic mineral coating agents, etc.), further regulating the release rate of nitrogen in urea-formaldehyde fertilizer (compensating for the limitations of a single urea-formaldehyde release cycle), improving the particle’s anti-caking and erosion resistance, and reducing the leaching loss of fertilizer in the soil. Ultimately, it produces “more stable release performance and stronger environmental adaptability” urea-formaldehyde coated slow-release fertilizer granules. This production line consists of a batching system, a reactor, a granulator, a dryer, a cooler, screening equipment, coating machine, and packaging equipment.
