Definitions

  • Beater mills For the crushing of mineral, vegetable or embrittled substances, i.a. Beater mills are used, the stationary grinding track of which is equipped with wear plates and blow bars, which are accommodated between the corresponding pressure plates. Wear plates and blow bars must be replaced at short intervals if the desired grain sizes are to be kept within the narrowest possible fluctuation range. This applies, albeit to a lesser extent, to the pressure plates on both sides of the blow bars.
  • a method and a device for carrying it out have become known according to document DE-PS 33 09 517, with which the strip steel knives in use are continuously or intermittently exchanged for sharp strip steel knives during operation. In accordance with the process, flakes of wood chips of constant quality and shape are always produced from wood chips. This eliminates the dead time required to replace blunted knives.
  • the object of the invention is to demonstrate a method for the granulation of mineral, vegetable or embrittled substances and a device for carrying it out, with which constant grain sizes can always be produced in uninterrupted operation.
  • the invention solves this problem by a method in which the wear plates of the stationary grinding track and blow bars in use, possibly together with their pressure plates arranged on both sides, continuously or intermittently against new parts of the aforementioned during operation Species are exchanged. Wear plates and blow bars, possibly together with their pressure plates, are placed in magazines on the feed side, from which they are fed to the grinding track via cylinder-operated slides. On the emptying side, simple magazines serve to hold the worn wear plates, blow bars and possibly also pressure plates. Depending on their different wear, wear plates, blow bars and possibly also pressure plates can be pushed through the stationary grinding path at different feed speeds.
  • wear plates and blow bars can be loaded with regrind higher than on the emptying side, in order to take into account the fact that the wear parts mentioned wear out more the longer they are used in the grinding chamber.
  • Such different loading of the regrind can be achieved by appropriate inclination of the impact shoes or - in the case of beater mills with horizontal axes - by inclining this axis.
  • wear plates and blow bars are made from thin strip steels with longitudinal grooves, the shape of which is completely identical. Each blow bar is held by one, possibly also two pressure plates, between which the blow bar is clamped.
  • the beater mill 1 consists of a cylindrical, stationary grinding track 2 with a rotor which is equipped with impact shoe arms 5 and impact shoes 4.
  • the stationary grinding track 2 is equipped on its inner jacket at symmetrical intervals with wear plates 7, the longitudinal grooves of which slide in exchangeable springs 11. Permanent magnets 16 ensure that the wear plates 7 sit flutter-free in the area of their counter lips 10.
  • the shape of the blow bars 6 is completely identical to that of the wear plates 7.
  • the central ring tension 12 according to FIG. 1 relieves the pressure plates 8 when the blow bars 6 are fed in cycles.
  • blow bars 6 and the wear plates 7 are stacked in magazine 9.
  • a slide 13 actuated via cylinder 14 pushes all blow bars 6 or wear plates 7 through the stationary grinding track 2 at intervals and one after the other, each with different feed speeds through the stationary grinding track 2.
  • slide 13 returns to its starting position , after which the compression springs 15 bring the next blow bar 6 or wear plate 7 into the loading position.
  • simple magazines receive the blow bars 6 or wear plates 7, which are designed as turning elements. (Not shown in the drawing).
