Definitions

  • the invention relates to a lining of a cylindrical Inner surface of a mixer with tiles, executed with cylindrical segment Large tiles, which are parallel to surface lines the cylindrical rows of large tiles arranged axially parallel to the cylindrical inner surface are.
  • Such linings are known from EP-B-0 241 723.
  • Wear cast or "steel cast” with hardnesses in the order of 560 - 720 HV10 and through the geometrical design of the tiles and in particular their laying and the assignment of the angle of mixing organ edges on the one hand and the angle of individual tile separating joints on the other succeeded in reducing the wear on the tile lining very much and thus extending its service life.
  • the composite tiles supplied as a kit, with at least one small tile has not yet been glued to the associated large tile.
  • Each composite tile is attached to the mixer trough by means of a plurality of bolts Fixed mixer wall and then expensive relative to the mixer wall aligned. Then the composite tile has to go through the missing small tile uncovered through hole of the large tile with mortar be poured out. Finally, the missing small tile is still open the large tile stuck on.
  • the invention is based, with simpler the task Assembly of the lining elements in the mixer trough the wear of the Lower the lining even further.
  • the mixers lined according to the invention are special for the production of liquid, pasty and dry building material mixtures provided, for example for the production of Cement-gravel-sand mixtures with or without the addition of water.
  • the small tiles are attached to the large tiles with a hardening binder, e.g. through a Plastic mortar or an adhesive, in particular a 2-component adhesive, a residual elasticity even after complete hardening owned so that the small tiles are elastically supported are. Care should be taken that the binder the areas of the Large tiles and small tiles are essentially complete covered so that a full support of the small tiles is guaranteed.
  • a hardening binder e.g. through a Plastic mortar or an adhesive, in particular a 2-component adhesive
  • Fixing the with small tiles occupied large tiles on the mixer construction can in usual way, e.g. by bolts, the bolts either loosely combined with holes in the respective large tiles can be or the bolts on the large tiles can be attached and through holes in the mixer construction can be passed through, then using nuts to be screwed.
  • the bolts either loosely combined with holes in the respective large tiles can be or the bolts on the large tiles can be attached and through holes in the mixer construction can be passed through, then using nuts to be screwed.
  • the small tiles can be essentially plane-parallel or in turn cylindrical segment-shaped be trained.
  • the use of plane-parallel Small tiles has the advantage that these are often on the market are available more easily and cheaply and in a variety of sizes are available. Whether plane-parallel small tiles or cylindrical segment-shaped small tiles are used, depends on a variety of requirements, for example of the availability of the respective small tiles, however also from the laying and fastening technology. This is followed in individual still received when using fastening techniques is spoken.
  • the large tiles are made according to the state of the art EP-B-0 241 723 is also known, preferably as a parallelogram or rectangular large tiles brought, often for the row-end large tiles Compensation tiles with differently designed outline shapes are used have to be brought.
  • the small tiles are parallel to the surface lines of the large tiles have running small tile longitudinal edges.
  • the Small tiles also step back towards the edges of the large tiles or project through them so that projections and Compensate for recesses in neighboring large tiles.
  • the small tiles are preferred as rectangular tiles or Parallelogram tiles executed, again the exception for small tiles, note that at the ends of rows of small tiles have to be done.
  • the small tiles as at least one row of small tiles Compensation small tiles are executed, which in Circumferential direction compared to the corresponding dimensions of the Small tiles of the other rows of small tiles differ Have dimensions. You can then do the circumferential compensation small tiles from the tiles of the other rows of small tiles Derive pruning.
  • the circumferential compensation small tiles can in particular be laid along a large tile longitudinal edge.
  • the length compensation small tiles of neighboring rows of small tiles can overlap in the longitudinal direction of small tiles.
  • the individual tile joints of adjacent rows of small tiles along the joint row of small tiles can be offset against each other. In this way it is in turn ensured that there are no long, forced routes for abrasive mixed grains are created that lead to premature could cause wear.
  • the ones already covered with small tiles Large tiles by bolts on the inner circumferential surface of the mixer to attach, set from the interior of the mixer , it may prove necessary that at least one small tile from a mounting hole or interspersed or cut through a mounting cutout is which one is in flight or in overlap with a mounting hole of a large tile. But it is also possible and even preferred, for fixing the already large tiles covered with small tiles Bolts from the outside to pass the mixer wall through it and then only to intervene in the respective large tile. However, it can then be the case with thin-walled large tiles nevertheless prove necessary, holes or cutouts in the To provide small tiles at the location of the respective bolt.
  • the circumferential and longitudinal dimensions of a large tile correspond regularly about 3 to 8 times, preferably that 5 to 6 times the corresponding size of a small tile. In this way it is possible to use a single large tile For example, to install 30 small tiles that were previously on the respective large tile under easier installation conditions have been attached.
  • the large tiles to be covered with small tiles can be made from Sheet metal punched and cylindrically bent or rolled. If is intended to use conventional cast steel wear tiles, for example according to EP-B-0 241 723 with small tile coverings To combine large tiles, you will be the carrier for Small tiles certain large tiles with correspondingly smaller ones Wall thickness have to be executed so that at the borders between conventional large tiles and large tiles covered with small tiles the surface remains flush. Because those with small tiles occupied large tiles themselves no significant wear exposed, they can be made of relatively thin-walled sheet metal getting produced. But it should not be ruled out that also the large tiles to be covered with small tiles as Castings are made.
  • EP-B-0 241 723 there can be rear recesses according to the invention in the production of for small tile occupancy certain large tiles are omitted, so that wall thickness is saved and the wall thickness difference then for the Wall thickness of the small tiles is available.
  • the small tiles can in particular consist of oxide ceramic material, for example based on Al 2 O 3 .
  • Oxide-ceramic tiles are described, for example, in the "Kalenborn Handbook, New Edition 1990, from Kalenborn, Kalprotect - Dr. Mauritz GmbH & Co. KG, D-5467 Vettelunter 2, with the title: Wear protection, sliding conveyance, plastic system parts".
  • This manual refers in particular to pages 113-123; Copies of these pages are submitted together with a cover page and an imprint page as an attachment to this patent application and are intended to supplement the disclosure. It has been shown that the oxide ceramic small tiles show very high hardness and thus wear resistance, namely, for example, a hardness of 1150 HV2.5.
  • Such small tiles can still be covered with diamond dust Cutting discs are cut so that the extraction of fittings from standard tiles is possible.
  • the large tiles can also be used with liquid then backfilled hardened backing material.
  • the targeted introduction of such a backing material may be superfluous if - as already mentioned above - in Operation backfill anyway, such as cement slurry, accumulated behind the large tiles and hardened there.
  • the invention is particularly suitable for use in trough mixers, in which the inner peripheral surface of a cylindrical or semi-cylindrical mixing trough with the invention Tile covering is provided and within the mixing trough a mixing trough axis are arranged rotating elements.
  • a construction is in particular in EP-B-0 241 723 described and illustrated.
  • small tiles in a plane-parallel design or cylindrical embodiment is also of the type of Fasteners between large tile and small tile and from depending on the size coordination.
  • small small tiles i.e. Small tiles with little Tendon length can also be achieved using glue or plastic mortar then be attached to the large tiles if they are plane-parallel are manufactured.
  • glue or plastic mortar then be attached to the large tiles if they are plane-parallel are manufactured.
  • the plastic mortar or 2-component adhesive is preferred in such a viscosity on the large tiles and / or applied to the small tiles that an unintentional Flowing away is also avoided on gradients and on the other hand by pressing the small tiles against the large tile as equidistant as possible can.

  • a mixing shaft 12 is arranged in each of the two mixing troughs 10.
  • the mixing shafts 12 carry mixing elements 14 in in their central axial section Form of mixing blades, which are arranged so that they convey the mix in the two mixing troughs 10 in opposite directions and moving from mixing trough to mixing trough at the same time, while at the ends of the two mixing shafts 12
  • Transfer organs 16 are arranged, which ensure that at the ends of the two mixing troughs 10, the mix in opposite directions from one mixing trough to the other Mixing trough is transferred.
  • the transfer organs 16 a different angles of attack with respect to the mixing elements 14 have.

  • the angle enclosed between the normal line N and the speed vector v r of the resulting speed is denoted by ⁇ . It can be seen that, assuming an angle of attack ⁇ of approximately 45 ° and given the sizes of the peripheral speed v u and the sliding speed v g, the angle ⁇ between the normal line N and the resulting speed vector v r is considerably greater than 45 °.
  • the large tile row butt joints 24 are less at risk than the large tile single butt joints 26, because the speed component of the resulting speed v r in the direction of the large tile row butt joints 24 (this speed component is not shown) is significantly lower than the speed component in the direction of the large tile single butt joints 26.
  • This fact must be taken for granted due to the values of the angle of attack ⁇ which are usually around 45 ° and the usual friction coefficients between the material to be mixed and the edges of the mixer organ 28.
  • This means that primarily the large tile individual separating joints 26 are susceptible to premature wear, and that attempts to increase the service life of the tile lining are also concerned with achieving an improvement in the area of the large tile individual separating joints 26.
  • the large tiles 22 are again arranged in rows 22A, 22B etc., the large tile row parting lines 24 again running parallel to the surface line M.

  • the pronounced line movement no longer takes place along the large tile individual separating joints 26 and the material is pushed essentially vertically over the large tile individual separating joint 26 through the mixing organ edge 28. It has been shown that in this way, scouring along the large tile individual separating joint 26 and any damage to the mixing organ edge 28 which may result therefrom is further reduced.
