PROBLEM TO BE SOLVED: To provide a wind-power screening apparatus that can securely screen light-weight objects from heavy-weight objects.SOLUTION: A support part 10 that extends in a supply direction from the terminal part of a feeder 3 that supplies a waste mixture D including heavy objects d1 and light-weight object d2 into a wind tunnel 5 to support the waste mixture D is formed at the terminal part. The support part 10 comprises a plurality of teeth 11 provided in series in the width direction of the feeder 3, where the teeth 11 are tapered from the terminal part toward the supply direction of the feeder 3. When the heavy objects d1 are to be separated from the light-weight object d2, both the time to separate the heavy objects d1 from the light-weight object d2 with air streams by these teeth 11 and the distance in the supply direction where the separation is performed lengthen, so that the separation can be performed gradually according to sizes of the heavy objects d1. The above prevents light-weight object d2 from being entangled with the heavy objects d1 to drop with the result that the light-weight object d2 can be accurately screened from the heavy objects d1. 【課題】重量物から軽量物を確実に選別することができる風力選別装置を提供する。【解決手段】重量物ｄ１と軽量物ｄ２ｔも含む混合廃棄物Ｄを風洞部５の内部に供給するフィーダ３の終端部には、当該終端部から供給方向へ延びて、混合廃棄物Ｄを支持する支持部１０が形成され、支持部１０は、フィーダ３の幅方向に沿って複数並設された歯部１１を備え、歯部１１は、フィーダ３の終端部から供給方向へ向かうに従って先細りとなる。この歯部１１により、空気流によって重量物ｄ１と軽量物ｄ２とを分離する時間及び当該分離が行われる供給方向に沿った距離が共に長くなり、重量物ｄ１の大きさに応じて当該分離を徐々に行うことができる。以上により、軽量物ｄ２が重量物ｄ１に巻き込まれて落下することを抑制する結果、重量物ｄ１から軽量物ｄ２を確実に選別することが可能となる。【選択図】図１
