Claim 9:
10. A device for classifying a materials mixture consisting of several materials or groups of materials, the device comprising:
a first transport unit to which the materials mixture can be fed by a feed device;
a second transport unit, which is arranged downstream in a transport direction of the materials mixture and at a distance from the first transport unit;
a first chute being provided between the first transport unit and the second transport unit, via which a first material or a first group of materials with a first fluid resistance can be separated from the materials mixture;
at least one third transport unit being arranged downstream in the transport direction of the materials mixture from the second transport unit;
wherein between the second transport unit and the third transport unit a passage for the materials or groups of materials is formed;
a second chute downstream of the second transport unit, through which at least the second material or the second group of materials having a second fluid resistance can be separated from the materials mixture, wherein the second chute is arranged between the second transport unit and the third transport unit or runs through the third transport unit and that the third transport unit is material-permeable and/or permeable for a further fluid current; and
a dissipation device, by which a first fluid current can be dissipated, and that the dissipation device comprises an adjustable flap configured to be open and closeable.
