Definitions

  • the invention relates to a lining for the drums of ball mills highly wear-resistant, pressed and sintered stones, especially aluminum or Zirconia stones.
  • Ball mills are used for the very fine grinding of various regrinds, especially for Milling industrial minerals.
  • the regrind is introduced into a drum together with balls and by rotating the Grind the drum. This is done in such a way that the balls and the regrind through the Rotation of the drum raised and knocked over at a certain height, so that the The regrind and the balls fall back into the deepest area of the drums.
  • ball mills with a drum liner made of cast iron, rubber, steatite, silex or porcelain, a profiled inner surface to provide.
  • the invention has for its object to a lining for drums of ball mills create with which there is an improved grinding performance, less contamination of the regrind and achieve a longer life of the lining.
  • the wavy surface can be formed on each stone as a whole wave or as a half wave be, so that in the second case neighboring stones with their wave valleys or wave crests butted into the drum.
  • the radius of the shafts can preferably be approximately the radius of the balls in the drum correspond, which nestle into the undulating surface in this way, whereby a particularly effective entrainment effect can be achieved.
  • the profiled surface can be made roof-shaped by adding a roof-shaped surface each stone is molded or by putting the high or low edges together the roof-shaped surface is formed by stones with different high side edges.
  • the roof or wave profiles can preferably be axially parallel through the drum run, but it is also possible to incline them at a small angle to the drum axis to run through the drum to the regrind with the balls within the Transport the drum in the axial direction.
  • Two-component adhesive instead of the two-component adhesive or the initial liability when using one Two-component glue can be used to ensure permanent magnets on the drum facing stone surface.
  • These permanent magnets can be round or strip-shaped and in corresponding Depressions of the back of the stone used, in particular glued.
  • a cut drum 1 made of steel is shown from a ball mill, with the balls 2 and regrind 3 is loaded.
  • the drum 1 is lined with highly wear-resistant, pressed and sintered stones, in particular aluminum or zirconium oxide stones 4 or stones made of a similar material, the surface facing the inside of the drum has a wave profile 5 has. In the example shown in FIG. 1, each stone 4 has a full wave profile 5.
  • the radius of the wave profile 5 corresponds approximately to the radius of the balls 2, which are in this way in nestle the troughs of the wave profile 5 so that they are in the manner shown taken and raised, overturned at the highest point and the regrind shred.
  • the wave profile 5 largely prevents the raised balls 2 from sliding back and the ground material 3 along the inner surface of the lining of the stones 4, so that the Balls 2 and the regrind 3 are actually essentially knocked over.
  • a roof-shaped surface can also be used, if stones 8 are used which have a roof-shaped surface 9.
  • a roof profile can be made put together by alternating the rows of stones with their high side edges and their low side edges against each other.
  • the surface profile that can be achieved with stones 6 and 10 is that with stones 4 or 8 the wave-shaped profile 5 or the roof-shaped profile 9 over a stone width completely repeated, while this is the case with the profiles composed of stones 6 and 10, respectively over two stone widths is the case.
  • permanent magnets are on the underside of the stones 4, 6, 8, 10 6, which are round, in depressions of the stones 4, 6, 8, 10th recessed permanent magnets 14 can act or in grooves of the stones 4, 6, 8, 10th embedded permanent magnetic strips 15, the stones 4, 6, 8, 10 will adhere directly the inner surface of the drum 1 made of steel.
  • the Use adhesion by means of permanent magnets 14, 15 to ensure immediate initial adhesion To achieve gluing of the lining, so that the lining can be built up without after Laying of some steep slopes must wait until the adhesive has hardened. Possibly. can the Adhesion of the stones 4, 6, 8, 10 can also be brought about by the permanent magnets 14, 15 alone, without the need for an additional adhesive.
  • Which type of fastening is used is in Dependent on the specific weight of the regrind, the drum diameter and the to decide the required application on a case-by-case basis.
