MIXER BARS CLEANING IN A RADIAL OR AXIAL MANNER

摘要

The invention relates to a mixer-kneading device for carrying out mechanical, chemical and/or thermal processes, consisting of mixing elements (A, R) disposed on a shaft (2, 3), extending approximately in the longitudinal direction of the shaft (2, 3) or being somewhat inclined and comprising at least one scraping edge (14, 18, 21). Said mixer-kneading device is characterised in that clearance angles (w1 - w6) are formed, respectively, in a direction leading away from the scraping edge (14, 18, 21) and which is opposite to the direction of movement of the mixer element.
