Abstract
A separating device that separates particulate superabsorbent polymers and liquid absorbent fibers included in a material of an absorbent article. The device includes: a belt member that moves along a predetermined moving direction while receiving the falling material on an upper surface; and an airflow supply mechanism that supplies an airflow in a direction opposite to the moving direction of the belt member, along the upper surface from a downstream side of the moving direction relative to a position where the material falls. In a case the superabsorbent polymers are sent to the downstream side of the moving direction by movement of the belt member, the airflow rolls the liquid absorbent fibers on the upper surface of the belt member and forms fiber balls while regulating movement of the liquid absorbent fibers to the downstream side of the moving direction, to separate the liquid absorbent fibers and the superabsorbent polymers.
