Flake copper powder production ball mill

Feb 01, 2009 Feb 01, 2009 Above-mentioned spherical copper powders, ZrO 2 ball milling media and dispersing agent, i.e. sodium dodecyl sulfate, were mixed in a container fixed on a planet-type grinding mill rotating at a rate of 250 rpm for 8–12 h, so that the precursor particles were processed to flake copper particles. The flake copper powders were recovered from
