    Abstract: 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.

    Abstract: The sheet manufacturing apparatus includes: a rough crushing unit that roughly crushes a raw material containing fibers; and a defibration unit that defibrates the roughly crushed raw material in a gas atmosphere. In addition, the sheet manufacturing apparatus includes: first and second web formers that accumulate defibrated substances obtained through a defibrating process and form webs; and a sheet former that forms a sheet of the second web. In addition, the sheet manufacturing apparatus includes: a vaporization-type humidifying unit that humidifies a space in which the raw material is roughly crushed by the rough crushing unit; and a mist-type humidifying unit that humidifies the webs that are formed by the first and second web formers.

    Abstract: A sheet manufacturing apparatus includes a defibration unit and a sheet forming unit. The defibration unit includes a rotating unit and a housing including a cover portion and a fixing unit attached to the cover portion and spaced apart from the rotating unit in a direction perpendicular to an axial direction of the rotating unit so as to form a gap between the rotating unit and the fixing unit. The defibrating unit is configured to cause the rotating unit to rotate and dry-defibrate a defibration object. The sheet forming unit is configured to form a sheet by depositing defibrated material. The rotating unit includes rotating plates base sections located on a side of a central rotation axis and protruding sections protruding out in a direction drawing away from the central rotation axis, and the rotating plates is stacked such that the protruding sections are in contact in the axial direction.
