Abstract
Official abstract text for this publication.
Provided is a kneading rotor, a batch kneader and a method of kneading materials capable of obtaining kneaded materials with higher quality in comparison to conventional kneaded materials when the materials to be kneaded are kneaded in a high temperature state. The kneading rotor comprises a rotor portion which is disposed in a kneading chamber of a chamber of a batch kneader, and applies shear force, by using a plurality of kneading blades, to materials to be kneaded which pass through a tip clearance. A first long blade of the plurality of kneading blades has an apex for forming, with the inner surface of the chamber forming the kneading chamber, three-staged tip clearances of different sizes configured from a combination of a large tip clearance, a mid tip clearance that is smaller than the large tip clearance, and a small tip clearance that is smaller than the mid tip clearance so as to be arranged in the longitudinal direction of the first long blade. Each of a second long blade, a first short blade and a second short blade of the plurality of kneading blades has an apex for forming, with the inner surface of the chamber forming the kneading chamber, a tip clearance of a size that is larger than or equal to the small tip clearance and smaller than or equal to the large tip clearance.
First claim
Opening claim text (preview).
The invention claimed is: 1. A kneading rotor inserted rotatably into a kneading chamber of a chamber of a batch kneader, comprising: a rotor portion which has a plurality of kneading blades on its peripheral surface, is disposed in the kneading chamber so as to form a tip clearance between apexes of the kneading blades and an inner surface of the chamber forming the kneading chamber, and applies shear force, by using the kneading blades, to materials to be kneaded which pass thro…
