The purpose of the invention is to prevent accumulation of particulates on the outside of a net body of a particulate sifter having a cylindrical net body and to extend the lifetime of the net body. To achieve the purpose, in a particulate sifter which is provided with a sieve (21) having a cylindrical net body (26) extending in a horizontal direction and a booster having rotating blades which rotate along the inner surface of the net body (26) and which separates particulates that pass through the net body (26) from particulates and/or foreign substances that do not pass through the net body (26) while agitating the particulates that have flowed inside the sieve (21) with the booster, the sieve (21) is located rotatably around the central axis of the cylindrical net body (26). The sieve (21) may be rotated forcibly by an electric motor as a driving source or may be rotated by kinetic energy of particulate -air mixture agitated by rotating blades without a driving source.
