METHOD OF PREPARING POROUS GRANULAR AMMONIUM NITRATE Russian patent published in 1998 - IPC

Abstract RU 2121969 C1

FIELD: manufacture of porous and explosion-proof explosives. SUBSTANCE: in concentrated of formula: NH4NO3 prior to granulation stage, is added sugar production waste, namely saccharose containing sugar beet molasses. In order to prepare porous ammonium nitrate, 0.05-0.15 wt % (calculated in terms of saccharose) molasses solution should be added to obtain product. Characteristics of the product: imbibing capacity of granules is 9.7-13.5 g/100 g; retaining capacity is 5.5+-0.5%; H2O content is 0.35-0.60%; strength of granules is 500-700 g per granule. The resulting granules have high strength and are explosion-proof. EFFECT: more efficient preparation method. 2 tbl
