Triboelectric separation of differently composed material mixtures of non-conducting materials, especially plastics

摘要

The method involves conditioning reprocessed qualitative and quantitative differently composed non-conducting materials. The conditioned non-conducting material particles are strongly charged by intensive contact with an electrically conducting surface, which has been brought to a determined external positive or negative potential. The material specific positive or negative charged non-conducting material particles can then be sorted in an electrostatic field of the charge.
