  • Reduction of biuret and free ammonia during a method for producing fertilizer granulates containing urea
    Patent number: 7753985
    Abstract: The invention relates to a method for producing a fertilizing agent containing urea, by means of synthesis step, an evaporation process, and a granulation unit. According to said method, a self-regulating centrifugal pump is used to reduce the dwell time and to optimize the positioning of the components of the method for transporting the product flow of the evaporation process to the granulation unit.
