Patent ID: 8251226

Claim:
A method of separating residues from a thermal waste treatment into at least one fine fraction and one coarse fraction by which the residues are evacuated from a waste treatment plant in a dry state and separated into at least two fractions, wherein the residues are subjected to vibrations and conveyed downward in cascades over at least one stage on a plurality of non-perforated plates disposed diagonally offset one beneath the other and on freefall paths lying therein between, wherein the residues are conveyed along the plurality of non-perforated plates by vibrations and wherein, in the region of the freefall paths, the fine fraction is evacuated by wind sieving via a suction of gas flowing in a gas path having a gas horizontal direction opposite to a separation material horizontal direction of a separation path of the residues being separated along the plurality of non-perforated plates, the coarse fraction, except for the fine fraction evacuated by wind sieving, being conveyed along the cascade path.
