Abstract: A mixing apparatus has a mixing container disposed in the upper part of the mixing apparatus, preferably standing on a frame, which is open towards the top. The mixing container includes a single-shaft agitator disposed in the lower part of the mixing apparatus. The agitator has a vertically disposed agitator shaft to which is fastened an agitating tool configured as a rotor body which is disposed in the mixing container just above the container base. The single-shaft agitator is a statorless agitator and the rotor body fastened to the agitator shaft is surrounded by an external free space between the rotor body and the container wall of the mixing container. The agitator shaft is adjustable in its spacing distance from the cylinder axis.
