Patent number: 8926166Abstract: 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.Type: GrantFiled: January 13, 2010Date of Patent: January 6, 2015Assignee: Kobe Steel, Ltd.Inventors: Norifumi Yoshida, Masaaki Uemura, Hiromi Nakano, Katsunobu Hagiwara, Kimio Inoue, Mika Nishida, Kazuhisa Fukutani
