Metal powder collecting device of waste friction materials when friction materials on brake pads for automobiles are made available

摘要

The present invention relates to a metal powder recovery device for waste friction material generated during the processing of friction material for brake pads for automobiles. When the magnet feeder 12 supplies the waste friction material in the supply tank 10 to the vibrating screen 14, vibrating While being transported along the screen 14, light general waste friction material or particulate metal is scattered by the hot air from the air supply fan 16 and heater 18, and the heavy particulate metal powder compared to the general waste friction material is the first cyclone dust collector 26. In addition, the lightweight general waste friction material passes through the first cyclone dust collector 26 and is collected by the second cyclone dust collector 28, and heavy metals are collected by their own weight by the vibrating screen 14 and the discharge pipe at the bottom of the 20. It is designed to be able to recover copper-based metal from the waste friction material by dropping and discharging along the line.
