A titanium sponge crushing and sorting device solves the problems of the mode of sorting titanium sponge manually, namely, high labor intensity and inaccurate titanium sponge sorting. The sorting device comprises a screen body. The utility model is characterized in that a rectangular opening is arranged in the center of the screen; a screen piece matched with the opening is arranged on the opening; a blanking trough is arranged on the lower part of the screen body. The utility model has the advantages that titanium sponge is sorted accurately and reliably by adopting the screen piece for size sorting; the titanium sponge smaller than the mesh of the screen piece directly enters the next crusher through the blanking trough; the titanium sponge larger than the mesh of the screen piece is left in the screen body; and an operator just needs to return the titanium sponge in the screen body to the crusher, thus not only reducing the labor intensity of operators, but also improving the work efficiency. In addition, the incidence of equipment breakdown is reduced, and the service life of the equipment is prolonged.
