摘要：
The invention relates to the method of nitrogen-sulphur granular fertilizer formulation from ammonium nitrate, ammonium sulphate and/or aluminium ammonium sulphate and/or aluminium sulphate, sulphuric acid, and ammonia, wherein a slurry is formed first from the mentioned components and, then, this slurry is granulated with a recycle and other inorganic components directly and/or after thickening at a temperature of 70 to 130 °C. In a continuous forced-mixing reactor of power of 1.5 to 25 kW/m 3 ; such slurry features the pH of 6.1 to 7.5 at the reactor output and the ratio of ammonium nitrate to ammonium sulphate 1.1 to 1.75 at the reactor output. For the mentioned method, the equipment comprising a mixing tank (1), to which a reactor (2) is connected, followed by a thickener (6) is used, wherein the reactor (2) is provided with a propeller and/or turbine stirrer.
