A conching machine having at least two rotors (6, 7, 10, 10') respectively arranged in a trough compartment (3, 4, 5) of a conching trough (1), with the trough walls (2, 15, 115) of the conching trough (1) of each rotor (6, 7, 10, 10') being arranged as closely surrounding each other. Of the rotors (6, 7, 10, 10') at least one rotor (6, 7) is designed with radially extending blades (8) and at least one further rotor as a cutter rotor (10, 10') with at least one cutting edge (12).

The fineness of bulk material, particularly of material to be ground, is determined by means of a flow measurement (DIN 66126) and by using a calibration correlation between medium particle size and permeability of the sample. The medium fineness of a continuous flow of bulk material determined in such a way at predetermined intervals of time may be used for adjusting roll mill parameters. In the same way, it is possible to calculate the bulk density, so that a compacting procedure subsequently to a milling procedure can be adjusted accordingly.
