Abstract
Procédé de granulation du chlorure de potassium, du nitrate de potassium, du sulfate de potassium, du carbonate de potassium, de la langbéinite ou de leurs mélanges, en vue d'obtenir des granulés, caractérisé en ce qu'il consiste à mélanger le sel de potassium avec de l'eau et avec un liant qui est un phosphate mono- ou diacide d'ammonium, de sodium ou de potassium, à raison de 15 à 150 kg par tonne de sel de potassium, à granuler le mélange et à le sécher. Obtention de granulés de sels de potassium de dimensions relativement importantes ayant une résistance mécanique permettant leur utilisation dans des engrais composés.
