Abstract
A lifting wall for a tube mill which has a discharge means with lifting vanes in order to transport the material being ground to discharge openings by the rotary movement of the tube mill. The lifting vanes are disposed obliquely with respect to the radial direction so that the material being ground slides promptly to the center where it is discharged through the discharge openings still below the horizontal longitudinal central plane of the tube mill. The lifting vanes are substantially flat and bent like blades in a region of the discharge openings.
