Abstract
A method and a device to separate conductive particles from a mixture of conductive and non-conductive particles comprising a carbon element extending along and close to but out of contact with a metal drum the carbon element being connected to one terminal of an electric welding machine and the drum to the other terminal so that conductive particles will be welded to the drum to be later scraped off.
Claims5
A method of separating a mixture of conductive particles and non-conductive particles including the steps of feeding said mixture onto an inclined carbon block, vibrating the block providing the block with an electrical potential of one polarity sufficient to weld, feeding these particles over a drum, rotating the drum, providing the drum with an opposite electrical potential, and scraping the conductive particles off of the drum at a point remote from the area of particle feeding.
An apparatus for separating a mixture of conductive particles and non-conductive particles comprising;
- welding means for charging said conductive particles,
- means for depositing said mixture onto a rotating drum at any area on said drum where the particles will fall off said drum,
- said means for depositing and said rotating drum being connected to said welding means at opposite polarities whereby said conductive particles will be welded to and carried on said drum to a point remote from said non-conductive particles and means at said point to remove said conductive particles.
