Abstract:
1. A helical-ribbon mixer having a rotation-symmetrical inner mixing vessel wall ( 2 ), a motor-driven central agitator shaft ( 3 ) therein, on which, on lateral agitator arms ( 5 ), at least one helical ribbon ( 4 ) is held close to the vessel wall downwardly sloping with a circular slope (SZ) in a direction of rotation (D), characterized in that the helical ribbon ( 4 ), vectorially combined circularly and radially, has a helical ribbon angle of slope (SN) relative to the horizontal that is greater than a gliding angle (G) on the helical ribbon ( 4 ) of a material (M) to be mixed; wherein the mixing vessel wall has a first cylinder section ( wherein the helical ribbon ( wherein the helical ribbon ( wherein the helical ribbon ( wherein the helical ribbon (
