PROBLEM TO BE SOLVED: To provide a selector for effectively selecting a selection object from an admixture including a plurality of selection objects.SOLUTION: A selector 100 comprises: a vibration screen having a grid plate-like screen part 101 supported in a state of being juxtaposed in a plurality in one direction at an interval at which a grid bar of a shape of projecting upward in an inverse V shape, drops a long length fine line-shaped first selection object, while selecting selection objects from the admixture included in a state of separating at least a long length fine line-shaped first selection object, a long length thick line-shaped second selection object and a long length dispersive third selection object, and an excitation part 102 for adding vibration to the screen part 101, in which the screen part is arranged in a state of inclining the extension direction of the grid bar from the horizontal direction so that the long length thick line-shaped second selection object is carried along the extension direction of the grid bar; and an air-blowing part 104 for blowing wind for dispersing the long length dispersive third selection object to the vibration screen. |
