The Technology of Obtaining of New Kinds of NPKS Fertilizers

Purpose: agriculture, the production of mineral fertilizers.

Brief description: a low-waste energy-saving technology that ensures the export-oriented highly concentrated complex sulfur-containing fertilizers and eliminates the formation of large-tonnage waste – phosphogypsum in the process of production has been developed .

Benefits:

– expanding the range and improving the quality of the product (improving the physical properties of the granules),

– increasing the degree of use of nutrients by reducing the rate of leaching of nitrogen from the soil;

– the presence of sulfur in the composition of fertilizers (up to 8%), the shortage of which is currently observed in most soils;

– a decrease in the volume of large-scale waste generated – phosphogypsum by eliminating the stage of its intermediate separation;

– the reduction of expenditure standards for phosphate raw materials per unit of output (on average up to 25-30%) when transferring existing plants to the production of complex fertilizers.
