Definitions

  • the invention relates to a tool for exposing partially closed openings, slots or gaps, for example in a grinding drum of a ball mill, in particular a ball mill for cement production.
  • Ball mills consist essentially of a horizontal or slightly inclined rotatable grinding drum and hardened steel balls inside.
  • the drum wall has drivers for the balls, so that they are carried on rotation of the grinding drum only up and fall down in the sequence on the mill insert or on the material to be ground and this break.
  • the broken fine ground material is subsequently continued in the axial direction of the drum and classified by means of openings, slots or gaps in a wall perpendicular to the axis.
  • the mills are temporarily turned off and manually, possibly with hammer and striking tools, the clamping pieces in an elaborate form removed from the columns of Klassierwand.
  • the invention is now the goal of providing a tool for a percussion device, with which an exposure of partially closed openings, slots or gaps in parts of a grinding drum of a ball mill reduced workload is reached or with which when using a hammer mechanism or a hammer device removal of clamping pieces from breakthroughs of a Klassierwand can be done in an economical manner.
  • a tool of the type mentioned in that for a use of a percussion device, such as an air hammer or hydraulic hammer, the tool a holding means or a clamping part with a spigot, which is connected to a fixing part of a working part with a longitudinal axis X
  • the working part has a support body and a flat portion or a blade and the support body is formed on one side with a projection with a part-cylindrical sliding surface and directed by the discharge normal to the generatrix of the sliding surface a flat portion or a blade to a rounded tip is continued.
  • the advantages achieved by the invention are essentially to be seen in the fact that the shape of the tool, in particular the flat area or the blade in cooperation with the partially cylindrical sliding surface of the wider support body upon impact with the tool exerts a percussion component on the clamping piece, which is a solution thereof out of the gap of the classifying wall.
  • the wider supporting body with its protruding sliding surfaces lies laterally on the penetration-limiting surfaces.
  • the insertion end is positively or positively connected by means of a cone receptacle with the fixing part of the working part, because such a particularly accurate and time-saving operation can be achieved.
  • the support body of the working part has a width, at least in the region of the sliding surface, which is greater than that of the openings, slots or gaps of a classifying wall of a grinding drum.
  • the flat portion or the blade of the support body has a thickness which is slightly smaller than the smallest width of the apertures, slots or columns a Klassierwand a grinding drum.
  • a further preferred embodiment of the invention provides that the angle ⁇ of the leading edge to the longitudinal axis X A of the working part towards the fixing part is less than 28 °, which facilitates a clamping part solution.
  • Fig. 1 shows an inventive tool 1 in oblique view.
  • a clamping part 12 which communicates with a hammer mechanism of a hammer device (not shown), has opposite an insertion end 11 which is fixed in a fixing part 2 of a working part 3 by means of a cone seat 13.
  • a clamping part 12 and a working part 3 may be formed from one piece.
  • the working part 3 comprises a cantilevered support body 31 having a part-cylindrical sliding surface 311 and a flat portion 32, which is also called blade, which flat portion 32 of the projection of the support body 31 opposite a lever edge 321 and the tip 323 of the flat portion 32 towards a guide edge 322 has ,
  • Fig. 2 shows a tool 1 in working position schematically.
  • a tool 1 according to the invention is positioned with its flat portion 32 in the slot obliquely with a so-called sliding angle ⁇ between the lever edge 321 and the support point P of the sliding surface 311 of the support body 31 on the classifying wall 4 parallel to the tool axis X A. If the sliding contact angle ⁇ now has a value of less than 45 °, a striking of the tool 1 by impacts results in a displacement thereof on the surface of the classifying wall 4 and such a force is applied to the clamping piece 5 with a component towards the surface.
  • Fig. 3 shows in view of a tool according to the invention with a clamping part 12 for a striker (not shown) and with a spigot 11 in a fixing part 2 of a working part 3.
  • the working part 3 has a support body 31, based on the axis X A of the tool has a one-sided projection with a part-cylindrical sliding surface 311.
  • a flat part 32 In continuation of the support body 3 is a flat part 32, which is also optionally called blade.
  • the generatrix of the part-cylindrical sliding surface 311 of the support body 31 opposite flanks 321, 322 formed on the flat part 32, wherein a lever edge 321 has an angle ⁇ to the longitudinal axis X A of less than 75 ° ( ⁇ ⁇ 75 °).
  • the angle ⁇ of a support surface 322 extending toward the tip 323 of the flat region 32 has an opening ⁇ opposite to the angle ⁇ and a size of ⁇ 28 ° (y ⁇ 28 °).
  • Fig. 4 shows the tool of Fig. 3 in plan view.
  • Fig. 5 conveys the tool of Fig. 4 in a section AA according to Fig. 3 ,
  • a tool according to the invention can also be produced in one piece or in one piece.
