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 gipsu. Sposób ten 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 gips o wilgotności do 0,23 i uziarnieniu 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, wprowadzaną w postaci kropel o średnicy do 6 mm lub w postaci strugi, pod ciśnieniem 10 - 30 kPa w ilości 100 - 250 części wagowych na 1000 części wagowych złoża, następnie na przesypujące się w bębnie złoże nanosi się porcję-gipsu w ilości 150 - 700 części wagowych na 1000 części wagowych zgranulowanego złoża w bębnie i kontynuuje granulację w czasie kolejnych 4 - 10 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 calcium mineral fertilizer from loose material, in the form of post-saturation mud, by its granulation, using water to moisturize it during granulation, using gypsum. This method consists in the fact that as bulk material from which the fertilizer is made, post-saturation mud with humidity up to 0.5 and grain size up to 2.5 mm, as well as gypsum with moisture content up to 0.23 and grain size up to 0.5 mm are used. first, a post-saturation mud is introduced into the horizontal drum granulator with periodic operation 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, then the granulation of mud is carried out at a rotational speed of the granulator drum of 10 - 25 turns / minute 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 stream, at a pressure of 10 - 30 kPa in an amount of 100 - 250 parts by weight on 1000 parts by weight of the bed, then a portion of gypsum in the amount of 150 - 700 parts by weight per 1000 parts by weight granulated is applied to the bed that flows in the drum. ego deposits in the drum and continues granulation for another 4 - 10 minutes, with water being introduced to the overflowing bed using a set of nozzles fixed axially, inside the granulator drum.
