装置。 A sealing device in a rotating part of a powder processing device that seals between a through hole formed in a stationary side member such as a casing containing powder and a rotating shaft disposed on the axis of the through hole. A first annular seal member fitted into the through hole is provided so as to come into contact with the inner circumferential surface of the through hole, while a portion of the rotating shaft is located on the side of the powder body from the first seal member. A second seal member is provided that is fitted so as to be in contact with the outer circumferential surface, and these two seal members are brought into elastic contact so as to be slidable around the axis of the rotating shaft, and the sliding contact portion of these two seal members and A sealing device for a rotating part of a powder or granular material processing apparatus, characterized in that an annular gap is formed between the inner circumferential surface of the through hole and the gap is filled with grease.
