Which domestic manufacturer of urea granulation nozzles is suitable for a production capacity of 1,500 tons per day, with a particle size of over 96%?

The urea granulation nozzle is one of the key devices in urea production; it is the final device that determines the appearance of the urea product, and it plays a very important role in the quality of urea products. Jintianhua adopts the technology developed by the 11th Research Institute of the Aerospace Industry Corporation. According to the information provided, the ZL-H type urea granulation rotary nozzle unit manufactured by Wenling Global Granulation Spraying Equipment Co., Ltd. features a buffer-type internally rotating isobaric urea granulation nozzle. Its technical advantages include the ability to address fluctuations in the liquid level on the upper and lower parts of the nozzle’s inner wall, thereby achieving pressure balance; it also allows for precise control over the diameter and velocity of the liquid jet, effectively expanding the spraying area. This improves the conditions under which particles are formed, enhances the cooling environment for these particles, and further boosts the appearance and quality of the urea product. The feeding device features a unique design that provides cushioned feeding, ensures stable flow velocity at the nozzle, and prevents overflow. The spray density is evenly distributed, improving the utilization rate of the tower diameter and reducing dust. The tower cross-section has no spraying humps or peaks; it does not stick to the tower walls or bottom, and there is no crossing of the spraying lines. It features high heat exchange efficiency; the discharge temperature in summer is <65°C, and the product does not clump during packaging. Up to 99% of the particles have a particle size of 0.85–2.8 mm; this ensures that the proportion of particles with a size of 1.3–2.3 mm is above 90% in summer, and that the proportion of particles with a size of 1.8–2.8 mm is above 90% in winter. Moreover, the particles are plump and uniformly shaped. Suitable for tower diameters of φ9–20m and urea production capacities of 80,000–520,000 tons per year. Most of the large fertilizer plants I’ve seen use foreign-made products; it’s advisable to inquire more about this, as it is a quite important and critical piece of equipment.
