| Abstract: | In the process of production of compound fertilizers by tower melt granulation, the factors affecting the formation of hiuret include mainly the heating temperature of mixtures, residence time, and the moisture and nitrogen content of materials. In the light of these influencing factors, neasures are proposed for lowering the biuret content. After renovation the effect is remarkable, and the mass fraction of biuret in the product can be controlled at 0.9% - 1.3%. |
