Abstract
A batch type kneader (1) is provided with a chamber (3) having a material supply port (5) which can be closed, a pair of rotors (4A, 4B) which are disposed in the chamber (3) so as to be rotatable in opposite directions, and wings (10) provided over the outer circumferential surfaces (10A) of the rotors (4A, 4B) in such a way that they (10) mesh with each other. In this kneader (1), a ratio S/D of a clearance S between the outer circumferential surfaces (10A) of the wings (10) of the rotors (4A, 4B) and an interior wall surface of the chamber (3) to an inner diameter D of the chamber (3) is set in the range of 0.01-0.02. The lands on the wings of the rotors have chamfers.
