摘要:
An electrostatic separator of the free-fall type for classifying triboelectrically charged substance mixtures. This separator has a separate voltage source connected to each of the electrodes forming a pair of electrodes in such a way that the one voltage source supplies a positive voltage against ground potential and the other voltage source supplies a negative voltage against ground potential. This causes the potential difference against ground to be equal to zero in the center of the separator.

An electrostatic free-fall separator has roller-shaped field electrodes which are formed as hollow rollers closed at both their ends without forming sharp edges and having horizontally extending longitudinal axes arranged at a field distance parallel to one another.
