Abstract

La présente invention concerne un procédé de préparation d’urée résistante à l’humidité spécifiquement pour un engrais mélangé, caractérisé par : l’ajout d’urée granulaire dans une extrémité avant d’un tambour d’enduction, un disque, ou un mélangeur ayant une fonction de mélange et l’enduction par pulvérisation de l’urée granulaire avec une couche d’un agent résistant à l’humidité dédié ; et l’enduction par pulvérisation de l’urée granulaire avec une couche de poudre d’oxyde de magnésium modifiée dans une extrémité arrière du cylindre d’enduction, du disque, ou du mélangeur ayant une fonction de mélange pour obtenir l’urée résistante à l’humidité spécifiquement pour un engrais mélangé. L’urée préparée par le procédé peut être mélangée de façon stable avec un engrais acide tel que le superphosphate de calcium sans absorber l’humidité, devenir humide ou s’agglomérer.The present invention relates to a method for preparing moisture resistant urea specifically for a mixed fertilizer, characterized by: adding granular urea to a front end of a coating drum, disc, or mixer having a mixing function and spray coating the granular urea with a layer of a dedicated moisture resistant agent; and spray coating the granular urea with a layer of modified magnesium oxide powder in a rear end of the coating cylinder, disc, or mixer having a mixing function to obtain the urea resistant to moisture specifically for a mixed fertilizer. The urea prepared by the process can be stably mixed with an acidic fertilizer such as calcium superphosphate without absorbing moisture, becoming wet, or clumping.
