Commodity property of carbonate-ammoniumnitratefertilizers on a basis of ammonium nitrate melt and limestone

The article studies the process of obtaining carbonate-ammonium nitrate (CAN) based on the mixing of melt ammonium nitrate (NH4NO3) with limestone from the Karmana deposit. In this case, the mass ratio of NH4NO3: CaCO3 varied from 100: 5 to 100: 80. For them, the composition, strength, caking capacity, porosity, absorption of dezilnogo fuel, hygroscopic points, sorption capacity and the dissolution rate of the granules were determined. Any amount of limestone flour dramatically reduces caking, porosity, absorption of diesel fuel, increases strength and dissolution rate of nitrate granules. The results of the sorption capacity of the CAN granules show that both samples with a moisture content of 5-6% do not lose their initial friability. It should be noted that when an AN reaches 3.5% of absorbed moisture, it starts to crumble, losing its friability. Therefore, for storage of fertilizers on the basis of the AN need to pack them in paper or plastic bags
