Operating method for a separator and separator

A separator for classifying, comprising:

• a separating gas supply comprising a water infeed for generating superheated steam as separating gas, and
• an adjusting or regulating means designed in such a way that the temperature of the superheated steam as separating gas is adjusted to be so low that in particular no condensation of the superheated steam occurs in the separator;
• wherein a pressure difference is generated by a compressor to convey the flow of the separating gas;
• and
• wherein a defined water quantity in the liquid state is supplied downstream from the compressor as a function of the temperature of the superheated steam downstream from the separator.

An operating method for a separator for classifying, the method comprising:

• supplying superheated steam to a separator as a separating gas, wherein a temperature of the superheated steam as the separating gas is selected to be so low that no condensation of the superheated steam occurs in the separator;
• wherein the superheated steam is generated by a supply of liquid water;
• wherein a pressure difference is generated by a compressor to convey a flow of the separating gas in a cycle;
• wherein a defined liquid quantity is supplied downstream from the compressor as a function of the temperature downstream from the separator;
• supplying a separating material to the separator via a separating material feed in a metered manner into a separator housing;
• wherein separating material that is coarse leaves the separator through a coarse material gate;
• and
• wherein separating material that is fine passes through a separator wheel and is conveyed into a filter supplied with superheated steam and leaves the filter through a fine material gate.
