    • PROBLEM TO BE SOLVED: To provide a screening method by slit bars and a screening device suppressing and further preventing adhesion of lithic raw material to slit bars with a simple mechanism, and increasing screening accuracy compared with a conventional one.
      SOLUTION: In the screening method using multiple slit bars 12 having spaces 11 from the upstream side to the downstream side, and tiltedly sliding down the lithic raw material on the slit bars 12 for screening, the surface layer of the slit bar 12 is composed of a rubber-like elastic body 13, and metallic wires 14 are disposed inside the rubber-like elastic body 13. The outer diameter of the slit bar 12 is 8-20 mm, and the thickness of the rubber-like elastic body 13 is 2.5 mm or more.
