A method and terms of process of dehydration and granoulooutvorennya azotno-caltsievo-gouminovih sircovmisnih fertilizers is definite with application of technique of psevdozridgennya, with the coefficient of the use of warmth over 60% at znevodenni. Technological parameters, at which dehydration of the liquid geterogennoi system with formation of spatial to framework from microcristaliv of sulfate to the ammonium in which the distributed macroparticles of carbonate of calcium and besieging on him colloid particles to goumatou potassium and forming of spatial structure of granules, are definite. In a theory ob–rountovano and it is experimentally confirmed, that at dehydration of the liquid systems of created on the basis of solution of termolabilnogo sulfate to the ammonium, deleting of moisture is a limiting stage. With the purpose of intensification of masoobminou a new construction of gas-distributing device and chamber of granoulyatora is developed, to allowed to realize the stroumenevi-poulsatsiynih mode of psevdozridgennya and by a volume interfusion of particles with frequency 5.7 Hertzs. It allowed to multiply intensity of evaporation of moisture from working solution in adequately to multiply 1,8.2 that the productivity at the granoulooutvorennyam theses of reduction of coefficient of granoulooutvorennya ??92%. The technological parameters of formation of granular azotno-caltsievo-gouminovih sircovmisnih fertilizers are definite with the layer structure of granules of sferopodibnoi form, rozmirom 1,5.4,5 mm and durability more than 10Н on a granule. Adequacy of mathematical model of formation of mineral gouminovih fertilizers is tested at application of the storoumenevo-poulsatsiynogo mode of psevdozridgennya and the method of computation of power of new cents of granulation necessary for stabilization to general dispersion composition of granules vehicle at the set mode of unloading of product is developed. As a result of researches there is the developed construction of granoulyatora with a psevdozridgenim layer for the receipt of azotno-caltsievo-gouminovih sircovmisnih fertilizers. A method and algorithm of computation of industrial granoulyatora is developed. The formulated technological bases are the that developed printsipovaa chart of industrial module Product Description popup.authors Гайдай С. Корнієнко Я.М, Ладієва Л.Р. Магазій М.П. Мельник М.
