Definitions

  • the invention relates to a roller press for crushing brittle grinding material, comprising at least two grinding rollers, a machine frame having at least one upper flange and / or at least one coherent upper frame member, and at least one lower flange and / or at least one coherent lower frame member having at least one frame head for stabilizing the at least one upper belt or the at least one continuous, upper frame element, when the roller press for changing the grinding rollers is open at the head, wherein the frame head consists of an upper cross-beam, which is supported by at least two lateral supports and with the at least one upper flange or the at least one continuous, upper frame member is connected.
  • roller press Another development in roller press technology is leading to ever lighter machine frames, so that they can be transported to remote locations, such as desert areas or hard to reach mines.
  • the always lighter machine frame are able to absorb the forces in the machine frame in the high pressure crushing, but the machine frame are relatively unstable if they have the open mouth described above.
  • German published patent application DE 10 2005 045 273 A1 discloses a machine frame for a high-pressure roll press, which has a cross-head supported by lateral supports on the head side, which supports the upper flange or the upper frame element in the open state of the machine frame.
  • the head-side cross-beam forms with its supports an integrated element of the machine frame, in which a head element of the machine frame is integrated, wherein the head element serves as an abutment for the high forces of the grinding rollers in the high pressure crushing.
  • the head element is suspended pendulum on the upper flange of the machine frame, and to the opening, the head element is pivoted to the side and upwards.
  • this machine frame is further formed, in which the head-side Maschinenrahmen- elements within the gate, which is formed by the upper cross member and the lateral supports are pushed to the side.
  • the head-side frame members are therefore taken laterally displaced in the crossbeam.
  • the cross-beam not only has to be so wide that through the door opening, the grinding rollers fit together with the width of the shaft. It must also fit the widths of the pushed aside side abutment as machine frame elements under the crossbar.
  • the roller press is undesirably wide and especially in a battery arrangement when multiple roller presses are arranged side by side in use, the increased space requirement of the roller presses is undesirable.
  • the extended crossbeam must be reinforced to accommodate the vertical forces without deformation.
  • the object of the invention is to provide a machine frame for a roller press for crushing brittle grinding material available, which is lighter than comparable machine frame and leads to a reduced space requirement of the corresponding roller press.
  • the object underlying the invention is achieved in that the machine frame is closed by at least one of the machine frame and the frame head completely detachable head piece. Further advantageous embodiments are specified in the subclaims.
  • the frame head with its cross-beam is independent of the head-side closure of the roller press, which serves as an abutment for the high forces in the grinding roller. It is different from the prior art that the head-end elements be completely removed and not be swung to the side and up or pushed aside. Since the corresponding developments in the field of machine frame for a roller press the head-side fasteners are always easier, as disclosed for example in DE 10 2010 048 214 A1, means the complete removability of the head-end closure of the machine frame less time than the pivoting or moving a lot heavy machine frame heads.
  • a light machine frame with a cross-beam, which is just so wide that it can accommodate the grinding rollers along with the length of the waves transversely through their door opening, so that the waves through the gate opening, through the upper cross-beam and lateral supports is formed, can happen.
  • the at least two lateral supports have such a large distance from each other that between them the grinding rollers with a length which extends in each case over a central shaft pass through.
  • This design allows for easier construction of the crossbeam because this no longer needs to accommodate head-end closures for the machine frame.
  • the entire construction for the machine frame can thus be simplified with simultaneously decreasing weight.
  • the machine frame completely detachable head piece is formed as a closure of the machine frame independently and without connection to the crossbar.
  • the cross-beam is relieved in the closed state of the machine frame by the machine frame completely detachable head piece. Due to this type of construction, the crossbeam can be constructed particularly easily, because it does not have to absorb any weight and dynamic load during operation of the roller press.
  • at least one rail for extending the grinding rollers is arranged below the cross-beam, wherein the grinding rollers are each mounted in their bearing blocks and slide the bearing blocks on the at least one rail.
  • FIG. 1 shows a roller press according to the invention with cross-beam, which is independent of head-side closure elements of a machine frame
  • Fig. 2 shows a machine frame with outlined position of the crossbeam.
  • FIG. 1 shows a roller press 1 in which two grinding rollers 2 and 3 are accommodated in a machine frame 4.
  • the machine frame 4 in this embodiment consists of an upper, continuous frame element 6, which has an upper flange 5 on each side of the machine frame 4.
  • a lower frame member 8 is provided, which also has two lower straps 7, one on each side of the machine frame 4.
  • the frame members 6 and 8 form each with a rear abutment 13 'and 14' (shown in the foreground) and a head-side frame closure as head pieces 13 and 14 a closed frame which receives the forces which the bearing blocks 17, 18, 19 and 20 apart drives.
  • the head elements 13 and 14 are removed and the grinding rollers 2, 3 together with their bearing blocks 17, 18, 19 and 20 are pushed out of the machine frame 4 (in the background).
  • an opening mouth is formed from the upper frame element 6 and the lower frame element 8, which can deform up to 10 t under its own weight of 5 t .
  • a cross-beam 10 is provided, which is connected to the upper frame member 6 and laterally supported by two supports 1 1 and 12.
  • the door opening which can be seen more clearly in FIG. 2, is just so wide that the width of the grinding rollers 2, 3 can be determined. together with the shaft across the door opening of cross-beam 10 and the two supports 1 1 and 12 passes.
  • the cross-beam 10 is shown with the two supports 1 1 and 12 in a front view, with other elements of the machine frame 4 are shown only schematically.
  • the cross-beam 10 protrudes on the left side of the image beyond the machine frame 4 than on the right side in the image to allow the extended on this page Wellenstumpfe the grinding rollers 2, 3 happen.
  • at least one rail 15 and 16 are anticipated, via which the bearing blocks 17, 18, Slide 19 and 20 to take up, for example, by a crane, can slide.
