Zusammenfassung:To provide a powdery material separation apparatus capable of efficiently separating at least one or more of powdery materials from a composite powdery material in which two or more powdery materials are composited, with a simple constitution.SOLUTION: A powder separation apparatus includes: a main body part 1 containing an upper side portion 10 of defining a truncated cone-shaped upper side space S1, a lower side portion 20 of defining a lower side space S2 and a sieve part 30 arranged between the upper side portion 10 and the lower side portion 20; an introduction part 50 for introducing a composite powdery material to the upper side space S1; a suction part 60 which is connected to the lower side portion 20, and sucks gas in the main body part 1 to produce an air flow in the main body part 1; and a gas introduction part 70 which is provided on the upper side portion 10 switchably between an open state and introduces gas into the upper side space S1 in the open state. Therein, a state of air flow in the main body 1 is changed by switching the open state and the closed state while sucking the gas in the main body part 1 by the suction part.SELECTED DRAWING: Figure 5 【課題】2以上の粉体が複合化された複合粉体から少なくとも1つ以上の粉体を簡素な構成で効率よく分離することができる粉体分離装置を提供する。【解決手段】円錐台状の上部側空間S1を規定する上部側部分10、下部側空間S2を規定する下部側部分20、および、上部側部分10と下部側部分20との間に配置されたふるい部30を含む本体部1と、複合粉体を上部側空間S1に導入するための導入部50と、下部側部分20に接続され、本体部1内の気体を吸引することで、本体部1内に気流を発生させる吸引部60と、開状態と閉状態とを切り替え可能に上部側部分10に設けられ、開状態において上部側空間S1に気体を導入する気体導入部70と、を備え、本体部1内の気体を吸引部によって吸引している状態で、開状態と閉状態とを切り替えることにより、本体部1内の気流の状態を変化させる。【選択図】図5
