PRODUCTION OF LIME-AMMONIUM NITRATE BASED ON CHALK, NITRATE AND AMMONIUM SULFATE

The article studies the process of obtaining carbonate-ammonium nitrate (CAN) based on mixing melt ammonium (NH4NO3) with chalk (СаСО3) and sulfate (NH4)2SO4). For granulation nitrate-sulfate-carbonate prilling method is applied using a tower. Determined composition properties new types fertilizers. It shown that ratio NH4NO3 : СаСО3 (NH4)2SO4 = 100 24 1 product contains 28,03% N, SO3 – 0,50%, 10% СаО has granule strength 6,03 MPa, which much higher than pure granules (1,32 MPa). Porosity absorption AN 22,0% 4,82 g. With an increase in proportion to ratio, porosity absorbency LAN 6,11% 2,57g, respectively. was revealed use (NH4)2SO4, additive at mass from 2 0,5 58 allows temperature onset decomposition by 2-6,7 1-1,3 times reduce 2,7-4,8 times.
