Kontinuierliches Knetapparat.

摘要

A kneading apparatus is constructed as follows. A plurality of rotatable discs (6,9,11) are mounted on a screw shaft (1a) disposed on a hollow cylinder (1), and a plurality of fixed doughnut members (17,18,21) are mounted on an inner wall of the hollow cylinder. The rotatable discs and fixed doughnut members are arranged alternately in an extending direction of the screw shaft. A screw flight (10A) is mounted helically on the rotatable shaft between two adjacent rotatable discs, and a notch (10B) is formed at a downstream end of the screw flight. The notch serves as a passage for material in an acute corner section defined between the more downstream located rotatable disc of the two adjacent ones and the screw flight. Accordingly, there will be little likelihood that the material is trapped in the acute corner section to form an accumulated mass therein and that old material is mixed into material being fed.
