POWDER SORTING DEVICE

摘要

A powder sorting device having a cylindrical mesh-like body capable of suppressing the accumulation of a powder on the outer side top part of the mesh-like body and increasing the life of the mesh-like body. The device comprises a sieve (21) disposed in a sieve casing into which the powder flows and having the cylindrical mesh-like body (26) extending in the horizontal direction and a booster disposed in the mesh-like body (26) and having a rotating blade rotating along the inner surface of the mesh-like body (26). The powder flowing into the sieve (21) is sorted into the powder and/or foreign matters not passing the mesh-like body (26) and the powder passing the mesh-like body while agitating the powder by the booster. The sieve (21) is disposed rotatably around the center axis of the cylinder of the mesh-like body (26). The sieve (21) may be forcibly rotated by a motor as a drive source, or the drive source may be abolished and the sieve may be rotated by the kinetic energy of a mixture agitated by the rotating blade.
