Abstract
The invention relates to 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 centre where it is discharged through the discharge openings still below the horizontal longitudinal central plane of the tube mill.
Claims10
Lifting wall for a tube mill with
- a front face (7) which is provided in inlet openings (7a) through which material being ground passes into the wall,
- a rear face (8) with discharge openings (8a) through which the material being ground which is located in the lifting wall is discharged, a central air duct (9) for an air stream (10) which is led through the tube mill, wherein the air duct has an air intake opening (9a) in the front face and an air outlet opening (9b) in the rear face of the lifting wall and the discharge openings are disposed in an annular region around the air outlet opening,
- and a discharge means with lifting vanes (11, 12) which transport the material being ground to the discharge openings by the rotary movement of the tube mill,
- characterised in that the lifting vanes are disposed obliquely with respect to the radial direction.
