When a predetermined period of time has elapsed and the mixing progresses, a so-called ``collaboration phenomenon'' may occur in which the materials to be mixed are well-balanced in the mixing tank and rotate together with the rotating mixing blades. When this phenomenon of co-mixing occurs, the substances to be mixed are not mixed with each other even though the mixing blades are rotating.
Therefore, a sufficient mixing effect cannot be achieved.

Therefore, it was not possible to uniformly eliminate the ``co-rotation phenomenon''.

The present invention provides a mixing method characterized by returning the mixing tank to its original arrangement after discharging the mixture to the outside of the tank.

, 43 and 44 into the kneading tank 2. As for the order of addition, first the sand is added, then the cement and the kneading water are added respectively. The mixture is kneaded evenly within a predetermined period of time from the start of the addition to the end of the addition. After kneading for a predetermined time, the hydraulic cylinder is driven as described above to sequentially incline the tank bottom 31 to a desired angle. After kneading in this inclined state for a required time, the tiltable leg table 12 is driven again to return the tank bottom 31 to the horizontal state yE, and then a required amount of gravel is thrown in to perform cross-tracking. Next, by the same means as above, the tank bottom 31 is tilted and the concrete is kneaded, and the discharge gate G is opened to discharge the mixed concrete to the outside of the tank.
