Abstract
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.
