Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To prevent noise from an apparatus for separating and withdrawal various electronic parts of a disassembled printed circuit board without braking the original form, when separating metal parts such as an aluminum fin at a high speed revolution in order to raise the purity of a material.
