Apparatus for polishing cathode plates for metal electrolytic refinery

摘要

Apparatus for polishing metal electrolytic refining cathode plates, in which cathode plates are transported individually by means of a series of transferring and hanging devices, with the cathode plates thus transferred being polished in a polishing mechanism while moved vertically and while their dielectric frame supporters are protected so as not to be subjected to the polishing operation effected by the polishing mechanism.
