Abstract
A process for preparing an elemental sulphur-containing fertilizer is disclosed. The process uses a dispersion mill, wherein a rotor turns within a slotted stator, to wet mill elemental sulphur in a liquid (preferably an aqueous liquid), thereby providing a dispersion of milled elemental sulphur in the liquid. The dispersion is combined with further components to provide a mixture of elemental sulphur and further components, and the mixture is granulated in a granulator unit to provide granulated elemental sulphur-containing fertilizer.
