Abstract
A defibrating apparatus includes a screen and housings, and side walls of the housings have inner surfaces that define the inner surface of a discharge path. Let communication hole be any through-hole that interconnects the defibrating chamber and the discharge path, and let discharge path-side opening edge be the opening edge, close to the discharge path, of the through-hole, then the screen has through-hole rows, each of which is formed by a plurality of communication holes arranged at an interval in a circumferential direction, and the through-hole row is provided at a position where the discharge path-side opening edge of the communication holes is overlapped with the inner surface as seen in a radial direction.

A defibrating apparatus comprising:
- a rotational body rotatable around a center at an axis of a rotational shaft;
- a defibrating chamber that stores the rotational body which when rotated, causes a defibrated material to be formed from a raw material containing fibers;
- a discharge path that communicates with the defibrating chamber, and receives the defibrated material discharged from the defibrating chamber;
- a circular annular wall that is provided at an interval from the rotational body in a radial direction of the rotational body, and that defines the defibrating chamber;
- a housing that forms the discharge path;
- and
- a plurality of through-holes provided in the annular wall, the plurality of through-holes penetrating the annular wall in the radial direction,
- wherein the discharge path has a width in an axial direction along the axis, and extends in a circumferential direction of the annular wall,
- the housing has a side wall extending in the circumferential direction, and the side wall has an inner surface that defines the discharge path,
- let a communication hole be any of the through-holes which interconnect the defibrating chamber and the discharge path, and let a discharge path-side opening edge be any of opening edges, close to the discharge path, of the through-holes, then
- the annular wall has a communication hole group which is formed by a plurality of communication holes, each of which is the communication hole, which are arranged at intervals in the circumferential direction, and
- the communication hole group is provided at a position where the discharge path-side opening edge of the communication hole is overlapped with the inner surface as seen in the radial direction.
