Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania granulowanego nawozu siarkowo-wapniowego na bazie reagipsu, w którym kompozycję rozdrobnionych na proszek stałych składników nawozu wprowadza się do granulatora, homogenizuje, zwilża się wodą podczas mieszania i formuje z niej granule, które następnie frakcjonuje się, suszy, chłodzi oraz konfekcjonuje frakcje granul o żądanej wielkości, polega na tym, że granulowaniu poddaje się kompozycję zawierającą co najmniej 60% wag. reagipsu w postaci proszku o średniej wielkości cząstek poniżej 100 µm oraz o wilgotności do 9% w temperaturze 50°C, co najmniej 10% wag, mikronizowanego siarczanu amonu o średniej wielkości cząstek poniżej 60 µm, przy czym co najmniej 80% tych cząstek ma wielkość 10 - 50 µm, do 10% wag. siarki koloidalnej o średniej wielkości cząstek poniżej 65 µm oraz ewentualnie 0,05 do 0,15% wag. nietoksycznego barwnika dopuszczalnego do stosowania w barwieniu nawozów, którą to kompozycję po homogenizacji zwilża się wodą podczas mieszania, a po uformowaniu granul i podzieleniu ich na frakcje, suszy się frakcję właściwą 1 - 6 mm w temp. do 100°C.The subject of the application is a method of producing granulated sulfur-calcium fertilizer based on reactips, in which the composition of powdered solid fertilizer components is introduced into the granulator, homogenized, moistened with water during mixing and granules are formed from it, which are then fractionated, dried, cooled and confectioning granules fractions of the desired size, consists in granulating a composition containing at least 60 wt. powder in the form of a powder with an average particle size less than 100 µm and a moisture content of up to 9% at 50 ° C, at least 10% by weight, micronized ammonium sulfate with an average particle size less than 60 µm, at least 80% of these particles 10 - 50 µm, up to 10 wt. colloidal sulfur with an average particle size below 65 μm and optionally 0.05 to 0.15 wt. non-toxic dye acceptable for use in dyeing fertilizers, which composition after homogenization is moistened with water during mixing, and after forming the granules and dividing them into fractions, the specific fraction 1 - 6 mm is dried at 100 ° C.
