Valuable metal recovery method of waste PCBs (Printed Circuit Boards)

摘要

The present invention relates to a valuable metal recovery method of waste PCBs (Printed Circuit Boards), the purpose of the waste PCBs that can easily recover the valuable metals from the waste PCBs by using a physical screening method using a vibration inclined plate It is to provide a valuable metal recovery method.;The present invention by using a hammer mill (impact crusher) to crush the waste PCBs so that the metal component is spherical, non-metallic particle shape is non-spherical and at the same time separate the metal component and non-metallic component, the vibration device in the lower center The angle of inclination of the vibrating inclination plate equipped with is adjusted to 0 ~ 50 ° with respect to the horizontal direction, and vibrates the vibrating inclination plate by using the vibrating device, and supplies waste PCBs pulverized material onto the inclination plate to vibrate by the vibration of the inclination plate. It is to provide a valuable metal recovery method of the waste PCBs (Printed Circuit Board) to collect the pulverized product falling into the lower side of the inclined plate separated into a metal component and a non-metal component in a recovery container.
