    摘要： A machine, particularly for producing cellulose fiber from waste paper with characteristics and yield comparable to virgin fiber, includes at least one conveyor body which is adapted to receive the waste material from which to obtain cellulose fiber; and at least one drum which contains inside it grinders adapted to grind the waste material for the production of the cellulose fiber, and which communicates with the conveyor body. The grinders include a grinding hammer which is arranged on the bottom of the drum and can rotate by way of a motor about a rotation axis.

    摘要： A raw-material feeding device includes: a storage section that includes a bottom section and a side wall standing from the bottom section and that stores, in a storage space surrounded by the bottom section and the side wall, small pieces of raw material constituted by a material containing fibers; a stirring section that is provided in the bottom section at a position facing the storage space, that includes a blade which rotates about a rotational axis extending in a direction in which the side wall stands, and that stirs the raw material in the storage space by rotating the blade; a first discharging section that is provided in the side wall so as to communicate with the storage space, that includes a first tubular body rotating about a first axis intersecting the rotational axis, and that discharges, upon rotation of the first tubular body, the raw material in the storage space to a processing section; and a second discharging section that is provided in the side wall at a position different from a position at which the first tubular body is provided so as to communicate with the storage space, that includes a second tubular body rotating about a second axis intersecting the rotational axis, and that discharges, upon rotation the second tubular body, the raw material in the storage space to the processing section.

    摘要： A processing device, a sheet manufacturing apparatus, a processing method, and a sheet manufacturing method enable quickly removing color material when color material is contained in a material containing fiber. A processing device has a defibrator configured to defibrate, in air, fibrous material containing fiber; and a particle supply device configured to supply particles of dry ice to the material containing fiber during defibration or after defibration. The material containing fiber contains color material; and the particles work to separate the color material for the fibers by colliding with the color material contained in the material containing fiber.

    摘要： A paper recycling device includes a dry type defibrator unit, a first transport unit, a classifier unit, and a paper forming unit. The first transport unit is configured to transport using air flow the defibrated material after being defibrated by the dry type defibrator unit. The classifier unit is configured classify by an air flow the defibrated material after being transported by the first transport unit. The paper forming unit is configured to form second paper with the defibrated material after being classified by the classifier unit. The first transport unit includes a transport pipe configured to move the defibrated material, with a cross section surface area of a portion of the transport pipe on a side closer to the classifier unit being smaller than a cross section surface area of a portion of the transport pipe on a side closer to the dry type defibrator.
