Title (EN) METHOD FOR PRODUCING GRANULATED CARBAMIDE
(FR) PROCÉDÉ DE FABRICATION DE CARBAMIDE EN GRANULES
(RU) СПОСОБ ПОЛУЧЕНИЯ ГРАНУЛИРОВАННОГО КАРБАМИДА
Abstract: front page image
(EN)The invention relates to methods for producing carbamide-based fertilizers and, more specifically, to methods for producing fertilizers containing carbamide and elemental sulfur. Sulfur-coated granulated carbamide is produced by introducing carbamide granules at a temperature of 20-60ºC into a drum which has blades mounted on the inside surface thereof and rotates at a speed equal to 81-99% of the critical speed of rotation of the drum, and by spraying a sulfur melt onto the surface of the carbamide granules. The melt is sprayed in the direction of the axis of rotation of the drum. The method provides for the even coating of the granules with sulfur.
(FR)L'invention concerne des procédés de fabrication d'engrais à base de carbamide et notamment des procédés de fabrication d'engrais à base de carbamide et de soufre élémentaire. Le carbamide granulé enrobé de souffre est obtenu par l'injection de granules de carbamide à une température de 20-60°С dans un tambour comportant à sa surface interne des pales et tournant à une vitesse égale à 81-99% de la vitesse critique de rotation du tambour et en projetant le soufre en fusion sur la surface des granules de carbamide. La pulvérisation du soufre en fusion se fait dans la direction de rotation de l'axe du tambour. Le procédé permet d'assurer la régularité d'enrobage des granules avec du soufre.
(RU)Изобретение относится к способам получения удобрений на основе карбамида, более конкретно - к способам получения удобрений, содержащих карбамид и элементарную серу. Гранулированный карбамид, покрытый серой, получают, вводя гранулы карбамида с температурой 20-60°С в барабан с лопастями, установленными на его внутренней поверхности, вращающийся со скоростью, составляющей 81-99% от критической скорости вращения барабана, и разбрызгивая расплав серы на поверхность гранул карбамида. Разбрызгивание расплава осуществляют в направлении оси вращения барабана. Способ обеспечивает равномерность покрытия гранул серой.
