The fertilizer granule polyurethane coating production line refers to a cluster of industrialized continuous production equipment and process systems specifically designed for coating polyurethane materials on fertilizer granules (such as urea, compound fertilizer, slow-release fertilizer, etc., solid granules). Its core function is to form a uniform and dense polyurethane film on the surface of fertilizer granules through standardized and automated processes, thereby optimizing the performance of the fertilizer. This production line is a key industrial equipment connecting basic fertilizers with high-performance polyurethane-coated fertilizers, and is widely used in large-scale production of high-end slow-release fertilizers and special fertilizers for economic crops in modern agriculture. The production line mainly consists of raw material pre-treatment system: preheating polishing equipment, coating system, post-treatment system, screening device, packaging equipment, etc.

Characteristics of the fertilizer granule polyurethane coating production line:
(1) Precise process, ensuring coating quality;
(2) Intelligent automation, improving production efficiency;
(3) Environmental protection and energy-saving design, meeting green production requirements;
(4) Strong product adaptability, meeting diverse needs;
(5) High quality stability, reducing production costs;
(6) Safe and reliable operation, ensuring production continuity.
