ELECTROSTATIC SEPARATION DEVICE FOR SORTING TRIBOELECTRICALLY CHARGED MIXTURES

摘要

The invention relates to an electrostatic separating device in the form of a free-fall separator for sorting triboelectrically charged mixtures of materials. A separate voltage source (9a, 9b,) is attached in such a manner to each of the electrodes forming a pair of electrodes that one of these sources supplies a positive voltage in relation to the earth potential and the other supplies a negative voltage in relation to the earth potential and as a result the potential difference relative to earth is zero in the middle of the separator.
