KNEADING ROTOR AND BATCH-TYPE KNEADING MACHINE

In kneading rotors (4, 5), a twist angle (θL) of long wing (13 to 15) constituting kneading wings (13 to 18) is between 38 degrees and 53 degrees inclusive. The long wing (13 to 15) includes, between the long wings and an inner surface of a casing, wing tops (13a to 15b) configured to form, along a...

Zusammenfassung:	In kneading rotors (4, 5), a twist angle (θL) of long wing (13 to 15) constituting kneading wings (13 to 18) is between 38 degrees and 53 degrees inclusive. The long wing (13 to 15) includes, between the long wings and an inner surface of a casing, wing tops (13a to 15b) configured to form, along a wing longitudinal direction, a first tip clearance (L), and a second tip clearance (S) narrower than the first tip clearance (L) in width. A central angle (θc) of the long wing (13 to 15) forming the second tip clearance (S) is between 5 degrees and 10 degrees inclusive.
