DEFIBRATING DEVICE AND SHEET MANUFACTURING APPARATUS

A defibrating device and sheet manufacturing apparatus attract and remove metal fragments when metal fragments are mixed with fibrous material. A defibrating device has a main unit with a defibration section configured to defibrate fibrous material， and a swirl section configured to produce a rotational current， and by the rotational current cause the fibrous material to rotate and flow into the defibration section. The main unit has a magnet unit that is disposed to the swirl section， and has a magnet that attracts by magnetic force metal fragments conveyed with the fibrous material to the swirl section.
