| 摘要 |
A particle separator for the separation of particulate mixtures comprising species that exhibit difference in electrical conductivity, comprising: a conductive surface including a separation zone over which said species move at a predetermined velocity, the conductivity of which is reduced over time through surface contamination; feeder means for feeding said species to said separation zone; an electrode arrangement spaced apart from said conductive surface and capable of inducing charge in conducting species as they move across said separation zone and lifting said conducting species from said conductive surface once charged; cleaning means located other than within said separation zone for producing a conductive surface free from surface contamination; and drive means for movement of said conductive surface relative to said electrode arrangement in order to bring said conductive surface free from surface contamination into a position where it constitutes said separation zone.
