To provide a powder sorter with improved powder sorting efficiency, a powder sorting device and a moving member.
By a sieve member F provided in the powder sorter 2 moved back and forth in the horizontal direction, the powder of a prescribed size is sorted into powder which has fallen from a mesh f0 and the powder left on the mesh f0. Since a difference between the maximum width of the moving member 1A mounted on the sieve member F inside the powder sorter 2 and the minimum width of a movable area is configured to be smaller than the amplitude of the powder sorter 2, the moving member 1A is flipped by the inner wall of the powder sorter 2 and moved. Thus, the moving area and moving speed of the moving member 1A are increased and the sorting efficiency is improved.
