针对高塔造粒生产复合肥存在塔壁结疤、产品结块的问题,开发了高塔熔体复合肥在造粒料浆三相点温度附近造粒的技术,阐述造粒料浆三相点温度的确定方法,以及在三相点附近造粒之优点。由于该造粒技术可使造粒温度比原来降低15℃左右,有效地防止了复合肥产品结块,降低了生产成本。 Aiming at the problem of scarring of tower wall and agglomeration of products in the process of tower granulation production of compound fertilizer, the technology of granulation of tower melt compound fertilizer near the three-phase temperature of granulation slurry has been developed. The method of determining the point temperature, and the advantages of granulation near the triple point. As the granulation technology can reduce the granulation temperature than the original about 15 ℃, effectively prevent the compost fertilizer products caking, reduce production costs.
