  • Patent number: 6227697
    Abstract: A mixer including a mixing vat (2), a mixer rotor (8) rotatable by a drive motor (6) around an essentially vertical axis of rotation (10) and a first mixing tool (14) mounted on the mixer rotor (8) so as to rotate around a first axis. Additionally located on the mixer rotor (8) is at least one further mixing tool (24), the mixing tools extending from above down into the mixing vat (2) or into the mixed substance. In order to optimize thorough mixing of the substances being mixed with minimum expense for construction, the mixer rotor (8) is provided with a set of gears (22) by which the first mixing tool (14) and a second rotatable mixing tool (18) are coupled such that the rotational speed of the second mixing tool (18) is greater than the rotational speed of the first mixing tool (14) by a predetermined factor.
