• Particle shape of copper milled by swing-hammer-type

    In order to apply a shape sorting technique to recover the copper component from printed wiring board (PWB) scrap the particle shape of copper milled by a swing-hammer-type impact mill was experimentally investigated. Copper plate and PWB scraps were used as samples. The effects of mill operating conditions i.e. hammer circumferential speed
