Abstract
Official abstract text for this publication.
A processing apparatus includes a powder material supply portion that supplies a powder material containing a first particle group consisting of a plurality of first particles, and a second particle group consisting of a plurality of second particles and having an average particle diameter larger than that of the first particle group, to a fiber-containing material containing a fiber during or after defibrating, and a powder material removing portion that removes at least a portion of the powder material from the fiber-containing material supplied with the powder material. It is preferable that the processing apparatus include a defibrating portion that defibrates the fiber-containing material on an upstream side of the powder material supply portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A processing method comprising: supplying a powder material containing a first particle group consisting of a plurality of first particles, and a second particle group consisting of a plurality of second particles and having an average particle diameter larger than that of the first particle group, to a fiber-containing material containing a fiber during defibrating; agitating the powder material and the fiber-containing material in a dry manner where the powder material and the fiber-containing material are mixed in air; and removing at least a portion of the powder material from the fiber-containing material supplied with the powder material, wherein the fiber-containing material contains a foreign material, the step of agitating the powder material and the fiber-containing material includes adsorbing the foreign material to the powder material, and the step of removing at least the portion of the powder material includes removing the foreign material adsorbed to the portion of the powder material. 2. A sheet manufacturing method comprising: supplying a powder material containing a first particle group consisting of a plurality of first particles, and a second particle group consisting of a plurality of second particles and having an average particle diameter larger than that of the first particle group, to a fiber-containing material containing a fiber during defibrating; agitating the powder material and the fiber-containing material in a dry manner where the powder material and the fiber-containing material are mixed in air; and removing at least a portion of the powder material from the fiber-containing material supplied with the powder material, wherein a sheet is manufactured from the fiber-containing material from which the powder material is removed, and wherein the fiber-containing material contains a foreign material, the step of agitating the powder material and the fiber-containing material includes adsorbing the foreign material to the powder material, and the step of removing at least the portion of the powder material includes removing the foreign material adsorbed to the portion of the powder material. 3. A processing method comprising: supplying a powder material containing a first particle and a second particle having a different composition from that of the first particle, to the fiber-containing material containing a fiber during defibrating; agitating the powder material and the fiber-containing material in a dry manner where the powder material and the fiber-containing material are mixed in air; and removing at least a portion of the powder material from the fiber-containing material supplied with the powder material, wherein the fiber-containing material contains a foreign material, the step of agitating the powder material and the fiber-containing material includes adsorbing the foreign material to the powder material, and the step of removing at least the portion of the powder material includes removing the foreign material adsorbed to the portion of the powder material. 4. A sheet manufacturing method comprising: supplying a powder material containing a first particle and a second particle having a different composition from that of the first particle, to a fiber-containing material containing a fiber during defibrating; agitating the powder material and the fiber-containing material in a dry manner where the powder material and the fiber-containing material are mixed in air; and removing at least a portion of the powder material from the fiber-containing material supplied with the powder material, wherein a sheet is manufactured from the fiber-containing material from which the powder material is removed, and wherein the fiber-containing material contains a foreign material, the step of agitating the powder material and the fiber-containing material includes adsorbing the foreign material to the powder material, and the step of removing at least the portion of the powder material includes removing the foreign material adsorbed to the portion of the powder material.
