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 wapiennej. Sposób charakteryzuje się 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 wapienną o uziarnieniu do 0,5 mm, i wilgotności do 0,05, 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 wapienną 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 granulatora.The subject of the application is a method of producing granulated mineral, calcium fertilizer from loose material, in the form of post-saturation mud, by its granulation, using water to moisturize it during granulation, using limestone flour. The method is characterized by the fact that as bulk material from which the fertilizer is made, post-saturation mud with a moisture content of up to 0.5 and grain size up to 2.5 mm, and limestone powder with a grain size up to 0.5 mm, and humidity up to 0.05 are used, wherein, first, a horizontal post-batch granulator is fed with post-saturation mud in such an amount that the ratio of the volume of introduced mud to the volume of the drum of the granulator is equal to 0.15 - 0.40, then the granulation of mud is carried out at the rotational speed of the granulator drum - 25 rpm for 4 - 10 minutes with simultaneous spraying of the granular bed 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 jet, at a pressure of 10 - 30 kPa in the amount of 100 - 280 parts by weight per 1000 parts by weight of the bed, then on the bed flowing in the drum limestone powder is applied in an amount of 150 - 700 parts by weight per 1000 parts parts by weight of the granulated bed in the drum and granulation continues for a further 4-20 minutes, with water entering the overflowing bed using a set of nozzles fixed axially, inside the granulator drum.
