The tube mill has an electric motor for rotationally driving the body. The electric motor has a rotor arranged around the body and connected to the body for rotation therewith and has a stator arranged stationarily around the rotor. The tube mill has a concrete element running around at least half the circumference of the stator yoke which is connected to the concrete element in such a way that forces acting on the stator yoke are transferred to the concrete element.
