Abstract

The invention relates to methods and apparatuses for producing fertilizers in granular form for example carbamide and ammonium nitrate. The fertilizer in granular form is produced by means of dispersing fertilizer melt in a volume of a granulating tower where drops of melt formed are cooled and are hardened when coming into contact with the rising flow of air. The granules produced are cooled in a separate fluidized bed apparatus with a horizontal movement of granules. In the fluidized bed apparatus separate removal of dust filled air is performed from at least two zones of the apparatus wherein the dust filled cooling air from the first zone of the apparatus in the direction of passage of the granules is directed into a device for purifying the dust filled air and the dust filled cooling air from the subsequent zones of the apparatus is directed into the granulating tower. The technical result consists in reducing the volume of dust filled air arriving for purification from the fluidized bed apparatus and reducing the energy losses and costs involved in the purification of this air as a result.
