Polishing recovery system

The utility model discloses a polishing recovery system. The polishing recovery system comprises an outer frame, a motor, a rotating wheel, an air curtain, an absorption tank and an outer cover, wherein the motor, the rotating wheel, the air curtain, the absorption tank and the outer cover are arranged on the outer frame, the rotating wheel is located in the outer cover and fixedly connected with a rotating shaft of the motor, the absorption tank is arranged below the rotating wheel, an inlet is formed between the outer cover and the outer frame, the air curtain is connected with the outer cover to seal the inlet, and a working inlet is formed in the air curtain. According to the polishing recovery system, because the air curtain is arranged, chippings or precious metal scraps generated in polishing are prevented from leaking out of the absorption tank, and waste of materials is effectively avoided; because the pneumatic motor replaces an original electric motor and will not generate heat when working continuously, an air conditioner of a working room can operate normally, and electricity is saved.
