Abstract[English]
A continuous method for making granules of methylene urea-isobutylene diurea (MU-IBDU) includes: injecting an MU-IBDU slurry including water and MU-IBDU particles into a fluid bed granulator, wherein the fluid bed granulator includes seed particles; injecting air into the fluid bed granulator to fluidize the seed particles in an air stream; spraying the MU-IBDU slurry over the fluidized seed particles to form granules of MU-IBDU; and removing the granules of MU-IBDU from the fluid bed granulator. Fertilizer compositions including the MU-IBDU granules are also described.[French]
L'invention concerne un procédé continu de fabrication de granulés de méthylène urée-isobutylène diurée (MU-IBDU), comprenant les étapes suivantes : l'injection d'une suspension de MU-IBDU comprenant de l'eau et des particules de MU-IBDU dans un granulateur à lit fluidisé, le granulateur à lit fluidisé comprenant des particules d'ensemencement; l'injection d'air dans le granulateur à lit fluidisé pour fluidiser les particules d'ensemencement dans un courant d'air; la pulvérisation de la suspension de MU-IBDU sur les particules d'ensemencement fluidisées pour former des granules de MU-IBDU; et le retrait des granules de MU-IBDU du granulateur à lit fluidisé. L'invention concerne également des compositions d'engrais comprenant les granulés MU-IBDU.
