Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania granulowanego nawozu mineralnego wapniowego, z materiału sypkiego, w postaci błota posaturacyjnego, w drodze jego granulacji, z użyciem wody do jego nawilżania podczas granulacji z wykorzystaniem mączki dolomitowej, który polega na tym, że jako materiał sypki, z którego wytwarza się nawóz stosuje się błoto posaturacyjne o wilgotności do 0,5 i o uziarnieniu do 2,5 mm, oraz mączkę dolomitową o wilgotności do 0,03 i rozmiarze ziaren do 0,5 mm przy czym najpierw do poziomego granulatora bębnowego o pracy okresowej wprowadza się błoto posaturacyjne w takiej ilości, aby stosunek objętości wprowadzonego błota do objętości bębna granulatora był równy 0,15 - 0,40, po czym prowadzi się granulację błota przy szybkości obrotowej bębna granulatora 10 - 25 obrotów/minutę w czasie 4 - 10 minut z równoczesnym natryskiwaniem granulowanego złoża wodą o temperaturze 10 - 21°C, wprowadzanym w postaci kropel o średnicy do 6 mm lub w postaci strugi, pod ciśnieniem 10 - 30 kPa w ilości 100 - 280 części wagowych na 1000 części wagowych złoża, następnie na przesypujące się w bębnie złoże nanosi się mączkę dolomitową w ilości 150 - 700 części wagowych na 1000 części wagowych zgranulowanego złoża w bębnie i kontynuuje granulację w czasie kolejnych 4 - 20 minut, przy czym wodę wprowadza się nad przesypujące się złoże za pomocą zestawu dysz umocowanych osiowo, wewnątrz bębna.The subject of the application is a method for the production of granulated calcium mineral fertilizer from loose material, in the form of post-saturation mud, by means of its granulation, with the use of water for moisturizing it during granulation with the use of dolomite flour, which consists in the fact that as loose material from which it produces fertilizer, post-saturation mud with a moisture content of up to 0.5 and grain size up to 2.5 mm, and dolomite flour with a moisture content of up to 0.03 and grain size up to 0.5 mm, with mud first introduced into the horizontal drum granulator with periodic work post-saturation in such an amount that the ratio of the volume of introduced mud to the volume of the granulator drum is equal to 0.15 - 0.40, followed by granulation of mud at a rotational speed of the granulator drum of 10 - 25 rpm for 4 - 10 minutes with simultaneous spraying granulated bed with water at a temperature of 10 - 21 ° C, introduced in the form of droplets with a diameter of icy up to 6 mm or in the form of a stream, at a pressure of 10-30 kPa in an amount of 100 - 280 parts by weight per 1000 parts by weight of a bed, then dolomite flour in the amount of 150 - 700 parts by weight per 1000 parts by weight is applied to the bed flowing in the drum. granulated bed in the drum and granulation continues over the next 4 - 20 minutes, with water being introduced to the overflowing bed using a set of nozzles fixed axially, inside the drum.
