Abstract
Inventia se refera la un procedeu de obtinere a unor granule de uree prin granulare sau pulverizare, conform caruia la uree supusa granularii sub forma de topitura sau solutie apoasa, se adauga oxid de magneziu ca atare sub forma de dolomita calcinata selectiv sau complet, într-o cantitate corespunzînd la 0,1...2% în greutate MgO calculata fata de uree.The invention relates to a process for obtaining urea granules by granulating or spraying, according to which in urea granulated as a melt or aqueous solution, magnesium oxide is added as such in the form of selectively or completely calcined dolomite, an amount corresponding to 0.1-2% by weight of MgO calculated from urea.
