Object of the invention is to finely granulate the granular substances with pollutants, such as the contaminated soils and incinerated ashes, adhered and to separate the pollutants from the granular substances efficiently and further to enable the unnoxious granular substances, from which pollutants as above have been separated, to be recycled. After carrying out fine granulation of the granular substances by carrying out a coarse disintegrating treatment on the granular substances with pollutants adhered through the first fine granulation machine 21, the granular substances, which have been finely granulated by the first fine granulation machine, are subjected to, by the second fine granulation machine 22, mutual polishing among the granular substances themselves being acted by mutual rubbing forces of the substance themselves and thus the pollutants, such as heavy metals and dioxin class substances adhering strongly to the surfaces of the granular substances are separated and also the granular substances without containing the pollutants are classified from the granular substances which have already been finely granulated by the first and second fine granulation machines by the vibrational screen 30 and the classification means 50.
