Abstract

Sposób wytwarzania granulowanego nawozu wapniowego, z materiału sypkiego, w postaci błota posaturacyjnego i mączki wapiennej, na drodze ich granulacji, z użyciem wody do ich nawilżania podczas granulacji, polegający tym, że jako materiał sypki stosuje się błoto posaturacyjne o wilgotności do 0,5 i o uziarnieniu do 2,5 mm oraz mączkę wapienną o wilgotności do 0,05 i uziarnieniu do 0,5 mm, przy czym granulację prowadzi się w talerzu granulatora (1) obracającego się z prędkością 8 - 25 Obr/min, do którego wprowadza się w sposób ciągły, ze stałą wydajnością, błoto posaturacyjne z jednoczesnym nawilżaniem złoża błota posaturacyjnego za pomocą zestawu dysz wodą o temperaturze 10 - 21°C, wprowadzaną w postaci kropel o średnicy do 6 mm lub w postaci strugi, pod ciśnieniem 10 - 30 kPa, w ilości takiej, że wydajność przepływu cieczy nawilżającej wynosi 0,15 - 0,35 wydajności dostarczanego błota, następnie wytworzone granule przesypuje się grawitacyjnie, w sposób ciągły, poprzez nachyloną burtę talerza granulatora (1) do obracającego się z prędkością 6 - 20 obrotów na minutę talerza granulatora (2), gdzie prowadzi się proces pudrowania, w czasie którego na przesypujące się wilgotne i zgranulowane złoże nanosi w sposób ciągły, mączką wapienną z wydajnością wynoszącą 0,15 - 0,55 ilości złoża dostarczanego do talerza granulatora (2) z talerza granulatora (1), po czym otrzymane w trakcie pudrowania suche powierzchniowo, niezlepiające się granulki przesypuje się w sposób ciągły z talerza granulatora (2) przez pochyloną burtę, przy czym stosuje się granulatory talerzowe o pracy ciągłej pochylone do poziomu pod kątem 41 - 49°, przy czym objętość talerza granulatora (2) jest 1,5 - 2 razy większa od objętości talerza granulatora (1).The method of producing granulated calcium fertilizer from loose material, in the form of post-saturation mud and limestone flour, by granulation, using water to moisturize them during granulation, consisting in the use of post-saturation mud with a moisture content of up to 0.5 o grain size up to 2.5 mm and lime flour with moisture content up to 0.05 and grain size up to 0.5 mm, whereby granulation is carried out in a plate of the granulator (1) rotating at a speed of 8 - 25 RPM, into which it is introduced in continuous, with constant efficiency, post-saturation mud with simultaneous moistening of the post-mud deposit using a set of nozzles with water at a temperature of 10 - 21 ° C, introduced in the form of droplets with a diameter of up to 6 mm or in the form of a stream, at a pressure of 10 - 30 kPa, in an amount such that the flow efficiency of the moisturizing liquid is 0.15 - 0.35 the efficiency of the supplied mud, then the granules are poured vitally, continuously, through the inclined side of the granulator plate (1) to the granulator plate rotating at a speed of 6 - 20 revolutions per minute (2), where the powdering process is carried out, during which it is applied to the pouring wet and granulated bed in a way continuous with limestone powder with a capacity of 0.15-0.55 the amount of bed delivered to the granulator plate (2) from the granulator plate (1), after which the dry, non-sticky granules obtained during powdering are poured continuously from the granulator plate (2) through the inclined side, with continuous plate granulator inclined to the level at an angle of 41 - 49 °, the volume of the granulator plate (2) is 1.5 - 2 times the volume of the granulator plate (1).
