  • the mixer is used for the production of mixtures of liquid, powdery or granular components as well as dry and / or moist mixtures, reference being made in particular to concrete mixtures. Due to the predetermined speed difference by means of the gearbox adaptation to the most diverse operating conditions in practice is not readily possible, or there are significant structural changes and measures for a conversion each required. While the speed of the single drive motor can be varied during operation, but the speed difference of the mixing tools remains unchanged.
