Abstract

Official abstract text for this publication.

A processing device has a fibrillation portion fibrillating fiber-containing materials containing fibers in the air, a particle supply portion supplying particles having Mohs' hardness of 2 or more and 5 or less to the fiber-containing materials during or after the fibrillating at the fibrillation portion for collision of the particles and the fiber-containing materials, and a particle removal portion removing the particles from the fiber-containing materials to which the particles are supplied.

First claim

Opening claim text (preview).

What is claimed is: 1. A processing device comprising: a raw material supply portion supplying fiber-containing materials containing fibers; a fibrillation portion fibrillating the fiber-containing materials containing the fibers in air; a particle supply portion supplying particles having Mohs' hardness of 2 or more and 5 or less to the fiber-containing materials during or after the fibrillating at the fibrillation portion for collision of the particles and the fiber-containing materials; and a particle removal portion removing the particles from the fiber-containing materials to which the particles are supplied in the particle supply portion, the particle supply portion containing a blower, the raw material supply portion being arranged upstream relative to the fibrillation portion, the particle supply portion, and the particle removal portion in a transporting direction of the fiber-containing materials, the particle supply portion connecting to the fibrillation portion, being disposed in the fibrillation portion, or being arranged downstream or upstream relative to the fibrillation portion in the transporting direction, the particle removal portion being arranged downstream relative to the fibrillation portion and the particle supply portion in the transporting direction. 2. The processing device according to claim 1 , wherein the blower ejects the particles such that the fiber-containing materials contact the particles while the fiber-containing materials are being stirred by ejection of the particles. 3. The processing device according to claim 1 , wherein the particle removal portion has a net-like body having an opening which allows passage of the particles but regulates passage of the fibers. 4. The processing device according to claim 1 , wherein the particle removal portion is configured so as to remove the particles by centrifugal separation.
