Abstract

The invention belongs to the field of fertilizers and relates to a method and apparatus 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 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 fertilizer 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 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 air from the subsequent zones of the apparatus is directed into the granulating tower. The technical result is 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.
