PRODUCTION LINE FOR PRODUCING LIME-AMMONIUM NITRATE Russian patent published in 2007 - IPC C05G1/08

Abstract RU 2309135 C2

FIELD: mineral fertilizers.

SUBSTANCE: invention relates to manufacturing mixed fertilizers from ammonium nitrate with limestone or calcium carbonate. Production line comprises ammonium nitrate-limestone mixing unit, wherein volume of the mixing unit case space is assumed lesser than or equal to volume found from formula: V_is = P_min·T_gc wherein V_is relates to internal space volume, m³, P_min minimum design productivity of lime-ammonium nitrate, m³/min, and T_gc minimal time for gasless contacting of limestone with ammonium nitrate melt, min. Minimal contact time without gas release for "ammonium nitrate melt-limestone" system is 5.24 min.

EFFECT: enabled gasless contacting of ammonium nitrate melt-limestone system due to properly selected unit space volume.
