Abstract

A separating device separates liquid absorbent fibers from a material including the liquid absorbent fibers of an absorbent article and impurities. The separating device includes: a case; an insertion port for inserting the material into the case on an airflow; a rotation member in the case for agitating and opening the material; and a discharge port for discharging the liquid absorbent fibers from inside the case on an airflow. The rotation member has a revolving axis with an axial direction along a predetermined direction from the insertion port to the discharge port, and a shaft member rotating around a rotating axis that has been set with an axial direction along the predetermined direction, while revolving around the revolving axis. The shaft member has protruding sections protruding outward and intersecting with an axial direction of the shaft member.
