Technologies for obtaining new types of complex NPKS fertilizers

Purpose: agriculture, production of mineral fertilizers Brief
description: a low-waste energy-saving technology has been developed, which ensures the production of export-oriented highly concentrated complex sulfur-containing fertilizers and the elimination of the formation of large-scale waste – phosphogypsum in the p
rocess of th
eir production. – increasing the degree of use of nutrients by reducing the rate of nitr
ogen leaching from the soil; – the presence of sulfur in the fertilizer (up to 8%), the deficit of w
hich is currently observed in most soils; – reducing the volume of the generated large-tonnage waste
– phosphogypsum by eliminating the stage of its intermediate allocation; – reduction of consumption rates for phosph
ate raw materials per unit of production (on average up to 25-30%) when transferring existing production facilities to the production of complex fertilizers.
