Double-helical mixer

摘要

A mixer for concrete mixing machines with a mixing trough has at least one mixer shaft which is mounted in the mixing trough and around which support helices are guided, which are attached to mixing arms in each case and on which mixing tools are attached via attachment means, such that they are adjustable. The support helices are formed from two rods or pipes in each case which run parallel to one another at a distance and to which the mixing tools are attached.
