A method and an apparatus for continuously manufacturing non-fired pellets, which comprise: continuously supplying green pellets containing a carbonating binder into a vertical type reactor to continuously pass the green pellets sequentially through a predrying zone, a carbonating zone and a drying zone in the vertical type reactor; blowing a predrying gas having a relative humidity of up to 70% and a temperature of from 40 DEG to 250 DEG C. into the predrying zone to predry the green pellets therein until the water content of the green pellets in the predyring zone falls within the range of from 1 to 7 wt. %; blowing a carbonating gas comprising carbon dioxide gas of from 5 to 95 vol. % and saturated steam of from 5 to 95 vol. % and having a temperature of from 30 DEG to 98 DEG C. into the carbonating zone to carbonate the carbonating binder contained in the green pellets therein; and blowing a drying gas at a temperature of from 100 DEG to 300 DEG C. into the drying zone to harden the green pellets therein, thereby continuously manufacturing non-fired pellets. |
