To provide an apparatus for recovering slag from waste capable of inexpensively producing firm aggregate and effectively utilizing the combustion heat of the waste as clean gas.
This slag recovering apparatus having forming devices 1, 11 for molten slag for subjecting the waste (d) to a high-temp. treatment, a water granulating device 7 for water cooling the resulted molten slag a to form water granulated slag (b) and a rotary kiln 16 for crystallizing the water granulated slag (b) is provided with a slag crushing device 14 before or behind the rotary kiln 16. The rotary kiln 16 which recovers the heat generated by the high-temp. treatment of the waste by a ceramic heat exchanger 18 and uses the heat as a heat source is preferable. At this time, a fan 15 for feeding the hot air as the heat source is preferably installed upstream of the rotary kiln 16. A dust collector to be exclusively used for removing the dust component in exhaust gases may be installed to the rotary kiln 16.
