Abstract

The invention concerns a method for continuously producing granulated fertilizer comprising the following steps: a) producing a mixture comprising lignite, magnesia oxide, at least one nutritive compound selected among nitrogen-containing nutritive compounds, phosphorus-containing nutritive compounds, potassium-containing nutritive compounds, carbon chain nutritive compounds of plant and/or animal origin and mixtures thereof, and the granules recycled at step e); b) granulating in an acid medium in the presence of water, overheated water vapour, sulphuric acid and the mixture obtained in a) until granules having a moisture content ranging between 3 to 19 wt. %, based on the weight of the granules, are obtained; c) drying the granules obtained in b) until a moisture content ranging between 0.1 and 15 wt. %, based on the weight of the granules, are obtained; d) sieving the granules and separating the granules; e) recycling in step a) oversized granules, preferably after grinding, and undersized granules. The invention also concerns a fertilizer material in the form of granules obtainable by said method.
