PROBLEM TO BE SOLVED: To provide a sieve device efficiently separating the mixture of particles of large and small size, and eliminating clogging of sieve mesh. SOLUTION: This sieve device comprises a mesh part formed in a vertical bowl type which is opened upward, having mesh holes selectively passing only small-size particles in the supplied mixture of particles of small and large size; and a first rotary drive part rotating the mesh part around its axial center. The small-size particles are discharged to the outside of the mesh part through the mesh holes by a centrifugal force imparted to the mesh part. The large-size particles are discharged from the upper periphery part of the mesh part. COPYRIGHT: (C)2005,JPO&NCIPI
