Abstract
A process for production of a granular urea product in a fluidized-bed where: small droplets () of fresh urea melt are contacted with a cooling medium to form solid particles, said solid particles () are contacted with droplets of urea melt () which are larger than said germ particles, the solid particles and said droplets forming together larger solid particles (), and said solid particles further increasing their size step by step and upon contact with droplets of urea melt, until the solid particles reaches a given size, and said solid particles are then subject to a further growing process by contact with liquid droplets now smaller than the solid particles, until a desired size of the granular product is reached.
