FIELD: methods of granulation of carbamide, for example in fluidized layer and fluidized-bed granulators. ^ SUBSTANCE: proposed method includes forming fluidized bed of seeding particles (S1) of agent to be granulated with essentially horizontal plane (P) and delivery of continuous flow (L) of fluid medium containing mother liquor at simultaneous forming of solid vortex (V) in fluidized bed with essentially horizontal axis, upper zone (Z1) where seeding particles are humidified and solvent contained in mother liquor is evaporated and lower zone (Z2) where mother liquor is hardened. ^ EFFECT: possibility of obtaining granules in narrow range of granulometric composition. ^ 16 cl, 5 dwg |
