Method and apparatus for securing the free flow properties and cooling of flowable, of ammonium nitrate-containing materials

摘要

The present invention relates to a method and a device for securing the free flow properties and cooling of flowable, of ammonium nitrate-containing materials during transportation, storage and in the conveyance of the materials by pipe - and / or tubular lines in and out of containers.The object of the present invention is a change in the original quality of the particles during transport, in the course of storage and reliably to prevent in the case of the delivery, in that an absorption of moisture from the surrounding air is effectively suppressed and thus a change of the free fluidity, a brück education during storage and during the discharging of transport - or storage containers and a change in the morphological properties of the particles is prevented, as well as to achieve a cooling of the filling.The solution of the object is attained by a method and a device for securing the free flow properties and cooling of granular, of ammonium nitrate-containing materials during transportation, storage and in the conveyance of the materials by tubular lines in and out of containers, which is characterized in that the flowable, of ammonium nitrate-containing materials in a dry and cold inert gas phase in a closed system transported, stored and transported and / or cooled.
