Title: SHEET-MANUFACTURING APPARATUS AND RAW MATERIAL DEFIBRATING APPARATUS
Abstract:
The present invention reduces accumulation of raw material between the coarse crushing unit and the defibrating unit. A sheet-manufacturing apparatus provided with: a coarse crushing unit for coarsely crushing a raw material, which at least contains fibers, in air to form small pieces; a defibrating unit for defibrating at least the small pieces in air; and a forming unit for forming sheets using the defibration product defibrated in the defibrating unit. The defibration amount, which is the amount defibrated per unit time by the defibrating unit, is greater than or equal to the coarse crushing amount, which is the amount coarsely crushed per unit time by the coarse crushing unit.
