Claim 10:
11. A method for classifying a materials mixture comprising several materials or material groups, the method comprising the steps of:
providing a device, in which the materials mixture is to be classified, having a first transport unit and a second transport unit being arranged in a transport direction of the materials mixture downstream of and at a distance to the first transport unit;
transporting the materials mixture from the first transport unit to the second transport unit;
removing the first material or the first group of materials with a first fluid resistance in a first chute being arranged between the first and the second transport unit;
feeding a remaining portion of the materials mixture to the second transport unit;
classifying at least one further material or at least one further group of materials in a second chute being arranged in the transport direction downstream of the second transport unit;
dropping at least a second material or the second group of materials having a second fluid resistance from the third transport unit or through the third transport unit out of the device;
providing a dissipation device arranged above the second transport unit; and
dissipating a first fluid current by the dissipation device.
