Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania granulowanego perlitu z odpadu perlitowego, który charakteryzuje się tym, że do granulatora talerzowego wprowadza się pył perlitowy i węglan wapnia w takiej ilości, aby stosunek objętości wprowadzonego pyłu perlitowego do objętości węglanu wapnia był z przedziału 1 — 3, po czym prowadzi się granulację przy szybkości obrotowej talerza granulatora 10 — 25 obrotów/minutę w czasie 5 — 20 minut z równoczesnym natryskiwaniem granulowanego złoża roztworem wodnym lignosulfonianu o stężeniu 30% — 90% jako substancją nawilżającą o temperaturze 10°C — 21°C, w ilości 2 — 5 części wagowych na 10 części wagowych złoża, po czym na przesypujące się w bębnie złoże nanosi się dodatkową porcję węglanu wapnia w ilości 1 — 2 części wagowych na 10 części wagowych początkowo dostarczonego perlitu i węglanu wapnia i kontynuuje granulację przez kolejnych 5 — 10 minut.The subject of the application is a method for producing granulated perlite from perlite waste, which is characterized in that perlite dust and calcium carbonate are introduced into a disc granulator in such an amount that the ratio of the volume of the introduced perlite dust to the volume of calcium carbonate is in the range of 1 - 3, then granulation is carried out at the rotational speed of the granulator disc of 10 - 25 rpm for 5 - 20 minutes with simultaneous spraying of the granulated bed with an aqueous solution of lignosulfonate with a concentration of 30% - 90% as a moisturizing substance at a temperature of 10°C - 21°C, in the amount of 2 - 5 parts by weight per 10 parts by weight of the bed, then an additional portion of calcium carbonate is applied to the bed flowing in the drum in the amount of 1 - 2 parts by weight per 10 parts by weight of the initially supplied perlite and calcium carbonate and granulation is continued for the next 5 minutes. 5 — 10 minutes.
