Abstract:
Electrostatic separator having a center for separating a triboelectrically charged mixture of substances, comprisinga pair of electrodes with each electrode having an opposite polarity vertically arranged in a housing, with a separating space being formed between said electrodes;wherein the electrodes comprise two electrode pairs positioned closely adjacent to each other, and said two pairs of electrodes being separated from each other by a nonconductive wall in such a way that the electrodes having the same polarity are in each case aligned, thereby forming two separation zones;each separation zone having an outlet for the intermediate material, an outlet for the positively charged material, and an outlet for the negatively charged material;an inlet chute for the separating space through which the mixture to be separated is freely dropping into the separating space;a separate voltage source being connected to each of said electrodes in such a way that one voltage source supplies a positive voltage against ground potential and another voltage source supplies a negative voltage against ground potential, causing a potential difference against ground to be equal to zero in the center of the separator, and said separating space containing said potential difference and causing separation products to be formed;whereby at least two final product outlets are present and the remaining material outlets are selectively connected via conveyor system with said inlet chute of one of the two separating spaces.
