Abstract

Cette invention concerne un procédé de fabrication d'un engrais contenant du soufre élémentaire. Ce procédé fait intervenir un broyeur à dispersion dans lequel un rotor tourne dans un stator à fentes pour humidifier du soufre élémentaire dans un liquide (de préférence un liquide aqueux) et obtenir ainsi une dispersion de soufre élémentaire moulu dans le liquide. Cette dispersion est combinée à d'autres composants pour donner un mélange de soufre et d'autres composants, lequel mélange est granulé dans une unité de granulation pour donner un engrais contenant du soufre élémentaire granulé.
