摘要
A method of granulating of water soluble fertilizers which contain kieserite with a mass content of between 25 and 100% and which have primary particles within a very wide grain spectrum with a fraction of at least 20% under 0.09 mm, includes the steps of providing a granulating material including kieserite, applying to the granulated material moisturizing liquid, prior to or during applying the moisturing liquid adding to the granulating material soluble and/or somewhat collodial soluble substances from the class of mono-, di- and polysaccharide and/or their simple hydrophilic derivatives in solid form or in a solution in which they provide a main part, in a dose of between 0.1 and 5% dry mass relative to a dry weight of the fresh granulated material, forming the granules, and drying the granules after their formation to a residual moisture of 1 to 6% of kieserite mass contained in them.
