Definitions

  • the invention relates to a tube mill according to the preamble of claim 1.
  • the invention has for its object to design a tube mill of the type mentioned in the preamble of claim 1 so that the downtime of the grinding system during maintenance and repair work in the drying chamber and transfer wall area is reduced to a minimum.
  • the cylinder of the drying chamber is connected to the bearing ring by means of separate screws that are accessible from the outside - regardless of the cylinder of the grinding chamber - and the cylinder of the drying chamber and the transfer wall that it supports are divided in the middle or several times in the axial direction -and repair work the mill so that the parting line is approximately horizontal or at least so that the upper part (half) of the cylinder of the drying chamber with the part (half) of the lifting wall carried by it can be unscrewed and replaced with a new one without that the grinding media filling of the grinding chamber must be removed for this purpose.
  • the other parts of the cylinder of the drying chamber and the transfer wall can then be exchanged in the same way (if the drying chamber cylinder and the transfer wall are divided in the middle, the mill can be rotated accordingly by about 180 ° to the other half of this cylinder and the transfer wall to be able to exchange).
  • a worn drying chamber with a transfer wall can be exchanged for a new one in the shortest possible time.
  • the grinding media filling need not be removed from the grinding chamber, nor is it necessary to dismantle the inlet device of the mill. This results in a very short downtime for the grinding system and one cost-effective repair of the removed parts outside the mill. If necessary, it is also possible to replace only a part or a half of the drying chamber and the transfer wall.
  • the tube mill 1 shown in FIG. 1 contains a drying chamber 2 and a grinding chamber 3. Between the drying chamber 2 and the grinding chamber 3, a transfer wall (lifting wall) 4, which can be seen in detail in FIGS. 2 and 3, is provided.
  • the tube mill 1 is mounted on the one hand in the area of a neck bearing 5 and on the other hand by means of a race 6 provided at the transition zone between drying chamber 2 and grinding chamber 3.
  • the cylinder 7 of the grinding chamber 3 is screwed to the web 6a of the race 6 via a flange 7a and screws 8.
  • the cylinder 9 of the drying chamber 2 is connected to the web 6a of the race 6 via a flange 9a and screws 10. As can be seen in FIG. 3, the screws 10 are arranged on a larger diameter than the screws 8 and are easily accessible from the outside.
  • the transfer wall 4 consists of individual segments 4a and is fastened to the cylinder 9 of the drying chamber 2 by means of screws 11. On the side facing the drying chamber 2, the transfer wall 4 is provided with openings 12 for the entry of the ground material. Lifting blades 13 convey the ground material to a central cone 14, via which the material passes into the grinding chamber 3 through an opening 15 in the wall part 16 facing the grinding chamber 3.
  • the cylinder 9 of the drying chamber 2 and the transfer wall 4 carried by it are divided centrally in the illustrated embodiment in the axial direction (of course, multiple axial division is also possible).
  • the parts) of the cylinder 9 of the drying chamber 2 are connected to one another via axially extending flanges 17 on the outer circumference of the cylinder 9 and via radially extending flanges 18 on the end wall of the cylinder.
  • the dividing joint of the transfer wall 4 extends in each case in the extension of the dividing joint of the cylinder 9 of the drying chamber 2. In order to ensure a perfect cohesion of the parts (halves) of the transfer wall 4 also in the inner area and to avoid internal screw connections as far as possible, the parts or the two Interlock halves of the transfer wall 4 via a plug connection.
  • the inlet device to the tube mill 1 is designated in FIG. 1 by 19 and the outlet device by 20.
  • 21 and 22 are ring gear and pinion for driving the tube mill.
  • the tube mill is rotated, for example, into the position shown in FIG. 1, in which the dividing joint (flanges 17, 18) between the two halves of the cylinder 9 of the drying chamber 2 is approximately horizontal, the upper half of the Cylinder 9 are replaced with the upper half of the lifting wall 4 carried thereby.
  • the lower half of the lifting wall 4 holds the grinding media located in the grinding chamber 3.
  • each screw connection point contains a single screw bolt 23, which completely penetrates the flanges 7'a and 9'a of the grinding chamber cylinder 7 'or drying chamber cylinder 9' including the race ring web 6'a which rest on opposite sides of the flange-like raceway web 6'a and with its bolt head 23a on the flange 7'a of the grinding chamber cylinder 7 'abuts.
  • auxiliary nut 24 is first screwed onto each of these bolts 23 (approximately on the central portion of the bolt), which establishes a reliable, independent first connection between the flange 7'a of the grinding chamber cylinder 7 'and the raceway web 6'a, the auxiliary nut 24 is expediently sunk in an associated recess 24a in the raceway web 6'a. In this way, the cylinder 7 'of the grinding chamber 3' is held non-positively on the web 6'a of the race 6 '.
  • a second connection which is independent of this described first connection is created with the same screw bolts 23 in that the flange 9'a of the drying chamber cylinder 9 'on the raceway web 6'a is non-positively with the aid of an outer nut 25 which is screwed onto the axially outer screw bolt end 23b is attached.
