Influence of material superficial moisture on insulation-metal electroseparation

The efficiency of electroseparating the constituents of a polyvinyl chloride (PVC)-metal (aluminium or copper) granular mixture depends on the moisture content of the materials. Laboratory research has been accomplished in order to determine the acceptable superficial humidity of the granules to be separated. The experimental study has been carried out on a roll-type laboratory separator with corona-electrostatic field. Ten samples of 50% PVC and 50% aluminum or copper, with a moisture content in the range 0>
