摘要

Mixer-kneading device comprises mixing elements (A, R) arranged on shafts (2, 3) extending in the longitudinal direction of the shaft or slightly inclined and having a scraping edge. Clearance angles are formed in a direction leading away from the scraping edge and opposite to the direction of movement of the mixer element.
