Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania aglomeratu z odpadowych strużyn garbarskich, w drodze granulacji w granulatorze talerzowym o działaniu okresowym, z wykorzystaniem mączki kredowej, który polega na tym, że jako materiał sypki, z którego wytwarza się aglomerat stosuje się przesiane, odpadowe strużyny z chromowych i/lub bezchromowych procesów garbarskich, o wilgotności 50 - 65% i uziarnieniu do 10 mm oraz mączkę kredową o wilgotności 0,5 - 5% i uziarnieniu do 0,5 mm, przy czym najpierw do strużyn wprowadza się mączkę kredową w ilości od 1 do 3 kg na każdy 1 kg masy strużyn, po czym miesza się je przez co najmniej 1 - 2 minut, a następnie dalej mieszając dostarcza się do mieszaniny 20 - 90% wodny roztwór szkła wodnego o temperaturze 10 - 30°C w ilości co najmniej 1500 g na 1000 g złoża, kolejno przez 5 - 10 minut prowadzi się dalsze mieszanie wilgotnej pulpy strużyn, mączki kredowej i szkła wodnego, po czym odciska się nadmiar cieczy tak by uzyskać wilgotność pulpy z zakresu 50 - 150% i tak utworzone jednorodne złoże granuluje się w granulatorze talerzowym w czasie 5 - 20 minut, po czym otrzymane aglomeraty suszy się w temperaturze 50 - 65°C przez co najmniej 24 godziny.The subject of the application is a method of producing an agglomerate from waste tannery shavings by granulation in a disc granulator with a periodic operation, using chalk flour, which consists in the use of sieved, waste shavings made of chromium and / or chrome-free tanning processes, with a moisture content of 50 - 65% and grain size up to 10 mm, and chalk flour with a moisture content of 0.5 - 5% and grain size up to 0.5 mm, firstly, chalk flour is introduced into the shavings in an amount from 1 to 3 kg for every 1 kg of the mass of the shavings, after which they are mixed for at least 1 - 2 minutes, and then, with further stirring, a 20 - 90% aqueous solution of water glass with a temperature of 10 - 30 ° C is fed to the mixture in an amount of at least 1500 g per 1000 g of bed, successively for 5-10 minutes further mixing of the wet shredded pulp, chalk flour and water glass, and then the excess liquid is squeezed out so as to obtain the pulp moisture in the range 50 - 150% of the homogeneous bed thus formed is granulated in a disc granulator for 5 - 20 minutes, then the obtained agglomerates are dried at a temperature of 50 - 65 ° C for at least 24 hours.
