Document Type and Number:
WIPO Patent Application WO/2010/082580
Kind Code:
A1
Abstract:
A kneading rotor, a batch kneader, and a material kneading method which are, when used to knead a material to be kneaded in a high-temperature condition, capable of providing a kneaded product having better quality than conventional kneaded products. A kneading rotor is provided with a rotor section which is disposed within a kneading chamber of a chamber of a batch kneader and applies shear force by kneading blades to a material to be kneaded which passes through tip clearances. A first long blade of the kneading blades has top ridges which form tip clearances of different sizes in three stages. The tip clearances are a large tip clearance, a medium tip clearance, and a small tip clearance which are arranged in the longitudinal direction of the first long blade, between the top ridges and the inner surface of the chamber in which the kneading chamber is formed. Among the kneading blades, a second long blade, a first short blade, and a second short blade each have a top ridge which forms a tip clearance of a size not smaller than the size of the small tip clearance but not greater than the size of the large tip clearance.
