A mixer comprises a mixing drum with blades and a rotary drive. It is equipped with an auxiliary working body – a rotor with blades in the form of curved surfaces of revolution mounted in the cavity of the drum on a shaft of wheel of a planetary gear secured in the bottom of the drum from the outside and mounted on the drum shaft. One of toothed wheels of the planetary gear is mounted with possibility of movement only in the direction opposite to the direction of rotation of the drum at a speed greater than the speed of rotation of the drum. |
