The utility model crushes the waste lithium batteries through the crushing device, and under the action of water, the compounds on the metal residue fall off. Under the action of the vibrating screen, water and compounds enter the compound collection pool through the vibrating screen, and large pieces of metal slag fall from the surface of the vibrating screen into the metal slag collection pool, thereby realizing the separation of the crushed materials.
