Abstract
Sposób wytwarzania nawozu mocznikowo-superfosfatowego, polega na dodawaniu mocznika do pulpy superfosfatowej zawierającej diwodorofosforan(V) wapnia i wodzian siarczanu(VI) wapnia lub tylko diwodorofosforan(V) wapnia otrzymanej w wyniku rozkładu rudy fosforanowej kwasem siarkowym(VI) lub fosforowym(V) lub ich mieszaniną według znanych rozwiązań technologicznych i następnie granulacji mieszaniny znanymi technikami bez lub w obecności dodatków zawierających makro- czy też mikroelementy, z zawrotem produktu, z kolei suszeniu, segregacji i chłodzeniu produktu. Sposób charakteryzuje się tym, że do ochłodzonej do temperatury 40 - 70°C pulpy superfosfatowej przed granulacją dodaje się mocznik w ilości odpowiadającej stosunkowi masowemu N do P2O5 od 0,5:1 do 2,5:1 i miesza się reagenty w czasie wystarczającym do rozpuszczenia mocznika. Korzystnie przed granulacją pulpę superfosfatową wraz z mocznikiem poddaje się zagęszczaniu przez odparowanie wody.The method of producing urea-superphosphate fertilizer consists in adding urea to superphosphate pulp containing calcium dihydrogen phosphate and calcium sulphate hydrate (VI) or only calcium dihydrogen phosphate obtained by the decomposition of phosphate ore with sulfuric (VI) or phosphoric (V) acid or a mixture thereof according to known technological solutions and subsequent granulation of the mixture by known techniques without or in the presence of additives containing macro- or microelements, with product recycling, in turn drying, segregation and cooling of the product. The method is characterized in that urea is added to the superphosphate pulp cooled to 40-70 ° C before granulation in an amount corresponding to the mass ratio N to P2O5 from 0.5: 1 to 2.5: 1 and the reagents are mixed for a sufficient time dissolving urea. Preferably, before granulation, the superphosphate pulp together with urea is concentrated by evaporation of water.
