Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania aglomeratu ze strużyn garbarskich na, drodze aglomeracji w granulatorze talerzowym o działaniu okresowym, z użyciem wodnego roztworu szkła wodnego oraz mączki dolomitowej. Przedmiotowy sposób polega na tym, że jako materiał sypki, z którego wytwarza się aglomerat stosuje się odpadowe strużyny z chromowych i bezchromowych procesów garbarskich oraz mączkę dolomitową, przy czym najpierw do granulatora wprowadza się strużyny, a w następnej kolejności dolomit. Mieszanie złoża zachodzi podczas obrotów talerza w czasie 2 - 5 minut. Następnie granulację prowadzi się przez 5 - 20 minut z równoczesnym natryskiwaniem granulowanego złoża wodnym roztworem szkła wodnego o temperaturze 10 - 30°C. Po zaprzestaniu nawilżania kontynuuje się granulację w czasie kolejnych 3 - 10 minut. Po zakończeniu granulacji uzyskane aglomeraty poddaje się suszeniu w temperaturze 50 - 65°C.The subject of the application is a method of producing an agglomerate from tannery shavings by agglomeration in a disc granulator with a batch operation, using an aqueous solution of water glass and dolomite flour. The method in question is that waste shavings from chrome and chrome-free tanning processes and dolomite flour are used as the bulk material from which the agglomerate is produced, and the shavings are introduced into the granulator first, and then dolomite. The mixing of the bed takes place during the rotation of the plate for 2 - 5 minutes. Then, the granulation is carried out for 5-20 minutes with simultaneous spraying of the granulated bed with an aqueous solution of water glass at a temperature of 10-30 ° C. After the humidification is stopped, the granulation is continued for a further 3 - 10 minutes. After the granulation is completed, the obtained agglomerates are dried at 50-65 ° C.
