A method for roller-granulating potassium-sulphate, using starch as an aid to granulation, the method involves dry activation-grinding of some of the potaasium-sulphate, moistening the material to be granulated with practically pure water, building u[ the green granules by rolling upon a granulating pan or in a tumbling barrel, and drying the said green granules, at a temperature of between 105 and 120C, to a residual moisture of between 0.1 and 0.5% in order to improve the wet ability of the primary particles, and to reduce the amount of water needed for moistening , a soluble salt of lignin-sulphonic acid is added in an amount of between 0.1 and 1kg/t of fresh material to be granulated
