For the granulation of nitrate-sulfate-carbonate melt, the prilling method is applied using a granulation tower. The composition and properties of new types of fertilizers were studied. It is shown that with the ratio NH4NO3: СаСО3: (NH4)2SO4 = 100: 24: 1 the product contains 28,03% - N, 0,50% - SO3, 10% - СаО and has a granule strength of 6.03 MPa, which is much higher than the strength of pure NH4NO3 granules (1.32 MPa). The absorption of pure AN granules is 4.82 g. With an increase in the proportion of chalk and ammonium sulfate to the NH4NO3: СаСО3: (NH4)2SO4 = 100: 24: 1 ratio, the absorbency of the LAN granules is 2.57g.
