  • the crushers used to crush the clinker material subject to considerable stress. For one thing this mechanical stresses caused by the process of Crushing arise, and on the other hand, it is thermal Stresses, as the crushers in operation temperatures up are exposed to 800 ° C. Considerable wear of breakers is the consequence. The resulting maintenance effort is high. To reduce various approaches are taken Service.
  • the invention is based on the object, starting from the last-mentioned prior art, an improved device to create, while maintaining the benefits in terms good maintainability is less expensive.
  • the interior of the rotationally fixed receiving the shaft is formed and provided the exterior with refractive elements is provided that the wave as a bunch of several elongated individual elements is designed so that they has a non-circular outer contour, and the crushing ring in his Inside several distributed over the circumference receiving openings for non-rotatable connection with the bundle.
  • the invention has recognized that by the inventive Execution of the wave as a bundle of several individual elements the flexural rigidity of the shaft can be increased. she has further recognized that with such a more rigid shaft acting on the crushing ring due to the power transmission Loads are reduced.
  • the inventive Arrangement the advantage that a large part of Inside of the ring used to transmit the torque becomes. This allows a uniform and thus better Power transmission between the shaft and the crushing ring. The stress resulting from the transmission of the material, in particular of the crushing ring, thereby reducing further.
  • the invention uses this, the crushing ring less consuming to produce. That allows it, the wave and above all to make the crushing ring from a cheaper material, which has to meet less stringent requirements. Furthermore the material thickness can be reduced.
  • a reduced material thickness But not only does it mean a material saving, but it also allows for identical external dimensions an increase in the inner diameter of the crushing ring. These Enlargement of the inner diameter in turn increases the for power transmission between shaft and crushing ring available standing area, which causes an even further reduction of the specific load.
  • the individual elements used for the bundle may be are any elongated elements. Preferably however, the individual elements are the same shape. This allows a particularly rational production and processing. It can be used with advantage pipes, as they usual commercial goods are available. This allows one particularly cost-effective construction of the shaft.
  • the individual elements can be any However, they preferably have a round Cross-section on.
  • the individual elements themselves can be massive or preferably hollow.
  • the shaft is designed as a hollow construction. Under a hollow construction is understood here, that the individual elements along the outer circumference of the shaft are arranged and enclose an inner cavity between them. Have proven to waves consisting of four to six individual elements.
  • the individual elements of the bundle can only be used at certain points, preferably at their ends, be connected to each other. However, a higher stability of the bundle can be achieved when the individual elements are assembled together. The means that the individual elements over the vast majority their length are connected to adjacent individual elements. Obtained in this way a particularly rigid structure of Wave.
  • the receiving openings in the contour of the Adapted external shape of the individual elements can be a largely flat system of individual elements can be achieved at the receiving openings of the crushing ring.
  • the specific force acting on the crushing ring decreases thereby.
  • This material of the crushing ring is thus exposed to only minor stresses.
  • Customized is not to be understood in the sense that the contour of the Individual elements identical to the shape of the receiving openings have to be. It suffices if a similarity of shape in the areas which is mainly the driving force between Transmit wave and crushing ring. Also should be one for all Operating conditions sufficient game to be present.
  • the receiving openings are interconnected. This results in the interior of the crushing ring common larger cavity, resulting in further material savings and a relief of the crushing ring leads.
  • the ratio between the outer diameter and the inner diameter of the crushing ring is preferably 0.7 to 0.9. It has been shown that such crushing rings a particularly good Relationship between low effort through material savings and wear resistance.
  • the individual elements of the bundle can be made of any Material that has sufficient temperature resistance has and suitable for transmitting the required forces is. Preferably, it consists of general structural steel St52-3.
  • the crushing ring is preferably made of a material on the one hand with high forces and on the other hand is wear-resistant, for example, from GS17CrMo55 or GX25CrNiSi at elevated temperature loads. To increase the wear resistance can be provided outside on the Breaking ring to apply a separate armor.
  • Fig. 1 shows a reference in its entirety 1 designated clinker cooler with a cooling grate 2, on the Good to be cooled in the form of a bed in the direction of the arrow emotional.
  • the clinker cooler 1 is preceded by a rotary kiln 4, its discharge end in an inlet shaft of the clinker cooler opens and the kiln in the in the drawing on the left side of the inlet shaft.
  • the reference numeral 6 crusher is located in the area of the discharge from the radiator grille 2 in a discharge chute 5.
  • the crusher comprises a frame 60 to which a plurality of Rollers 7 are arranged parallel to each other.
  • the rollers 7 are about pivot bearing (not shown) rotatably mounted on the Frame 60 is arranged.
  • a rotary drive 61 is outside of Clinker cooler 1 is arranged and is connected via a gear 62 with the crushing rollers 7 connected so that the crushing rollers 7 in opposite directions are driven. Under opposite here is understood that adjacent crushing rollers 7 in opposite Rotate directions.
  • the crushing roller according to the invention is the 7th more detailed in their individual parts as well as in the composite State shown.
  • the crushing roller 7 is composed from a shaft 8 and several deferred Breaking rings 9 (of which in Fig. 2 for clarity only one is shown).
  • the shaft 8 is designed as a bundle 80 of several individual elements, which are formed as round tubes 81.
  • round tubes 81 In the illustrated Embodiment, four round tubes 81 are used, but it can also be a different number of round tubes, For example, three, five or six round tubes, are used.
  • the Round tubes 81 are arranged so that their respective central axes lie on the vertices of a square whose edge length is dimensioned so that it matches the outside diameter of the Corresponds to pipes. In the places where neighboring Touch tubes 81, welds are provided which the Join tubes 81 into a stiff and loadable bundle.
  • end caps 82 At the ends of the tubes 81 end caps 82 are provided, which on one side shoots for the ends of the Having tubes 81, on its other side with a journal 83 for rotatably supporting the shaft in the frame are provided.
