Abstract
The invention relates to a method for producing a nitrogen-potash fertiliser. The inventive method consists in producing a mixture by supplying ammonium nitrate whose moisture content ranges from 15 to 7.5% in a quantity of 9.0-30.0 t/h, potassium chloride in a quantity of 7.0-24.0 t/h and, in addition ammonia in a quantity of 0.3-0.9 t/h.
