Abstract

Sposób wytwarzania granulowanego nawozu organiczno - wapniowego, z materiału sypkiego, w postaci błota posaturacyjnego i mączki drobnoziarnistej kredy, na drodze ich granulacji, z użyciem wodnego roztworu melasu do ich nawilżania podczas granulacji, polegający na tym, że jako materiał sypki stosuje się błoto posaturacyjne o wilgotności do 0,5 i o uziarnieniu do 2,5 mm oraz mączkę drobnoziarnistej kredy 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 10 - 70% wodnym roztworem melasu o temperaturze 15 - 55°C, wprowadzanym 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 0,125 - 0,3 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 się w sposób ciągły, mączkę drobnoziarnistej kredy 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).A method of producing granulated organic - calcium fertilizer from loose material, in the form of post-saturation mud and fine-grained chalk flour, by granulation, using an aqueous molasses solution for moisturizing them during granulation, consisting in the use of post-satiation mud as bulk material humidity up to 0.5 and grain size up to 2.5 mm, and fine-grained chalk with moisture content up to 0.05 and grain size up to 0.5 mm, where the granulation is carried out in a plate of the granulator (1) rotating at a speed of 8 - 25 rpm min, into which the post-saturation mud with simultaneous wetting of the post-saturation mud bed is introduced continuously, with a constant efficiency, by means of a nozzle set with 10 - 70% aqueous molasses solution at a temperature of 15 - 55 ° 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 rate of the moisturizing liquid is 0.125 - 0.3 efficiency of the supplied mud, then the granules produced are transferred by gravity, in a continuous way, through the inclined side of the granulator plate (1) to the granulator plate (2) rotating at a speed of 6-20 rpm, where the powdering process is carried out, in during which a fine flour of fine-grained chalk is applied to the pouring moist and granulated bed in a continuous manner with a capacity of 0.15-0.55 the amount of bed supplied to the granulator plate (2) from the granulator plate (1), and then obtained during powdering surface dry, non-sticky granules are continuously poured from the granulator plate (2) through the inclined side, with continuous disk disc granulators 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).
