    Abstract: Process and plant for the production of a urea ammonium sulfate granulate. In a first fluidized bed a first spraying liquid is sprayed comprising a urea melt and an aqueous solution of ammonium sulfate, e.g. a (near-) eutectic mixture. The bed temperature is below the crystallization temperature of the sprayed mixture. In a next compartment the granulate is fluidized to form a second fluidized bed. A second spraying liquid comprising a urea melt is sprayed into the second fluidized bed with a bed temperature higher than the bed temperature of the first fluidized bed and lower than the crystallization temperature of the sprayed second spraying liquid.
