Definitions

  • the invention relates to a grinding machine for mechanical processing, in particular Milling a paper fiber suspension, which is provided with at least two clothing carriers, of which at least one rotatable, with attachments attached thereto, each having a working side with a variety of Mahlleisten and intervening grooves and a back, with the Set on the clothing carrier can be attached, and have a set for the mechanical processing, in particular grinding a paper fiber suspension in a grinding machine with a working side, which has a plurality of Mahlleisten and intermediate grooves, the be flowed through in parallel by the paper fiber suspension during operation of the grinding machine, as well as with a back with which it can be attached to the clothing carrier of the grinding machine.
  • Grinders of this type are used for grinding suspended in water pulp. sets, which are used in grinding machines, refer to the lying on the front work surfaces Mahlleisten and grooves on, which is why one speaks of "knife sets". When grinding in Refiners the suspension usually has a solids content of about 2-8%. Grinding machines with Trimmings of this type are provided, have at least one rotor and at least one stator with disc or conical surfaces on which the trimmings are attached with their backs, e.g. be screwed on. Such a rotor or stator thus serves as a clothing carrier.
  • the invention is based on the object, grinding machines of the type mentioned or in it used trimmings so that the grinding technology effect better influences and can be optimized.
  • the invention offers the possibility of the grinding effect optimally to the grinding technology To adapt requirements by a combination of different knife shapes or grooves can be chosen.
  • Mahlleisten and grooves - viewed on the same circumference - kept the same. It was assumed that the shape and the angle of Mahlleisten for a special purpose are optimized and therefore used evenly for all trimmings involved in the grinding become.
  • the subject invention allows combinations of e.g. different Knife widths, different grooves or different cutting angles so that set the grinding result can be better adapted to the requirements. Generally prevail Rotor fittings considerable centrifugal forces, so that in their grooves the flow conditions are different than in the Statorgarnituren with which they interact. The mentioned Differences can be realized both within a set or by combination of different sets, if several of these are used on a clothing carrier.
  • the additional effort required is usually low, especially if the trimmings be poured, which is readily possible even with fine trimmings.
  • additional Measure wear-resistant coatings can be applied to the service life of Lengthen set.
  • the grinding strips are manufactured separately and then on one Base plate fixed, e.g. soldered. Even then, the invention with little extra effort will be realized.
  • a grinding machine of the type considered here has at least two clothing carrier 1 or 2, from in each case only a part is shown in Fig. 1.
  • the clothing carrier is 1 a rotor which is moved relative to the stationary clothing carrier 2 (stator), indicated by an arrow 10 is indicated.
  • On both clothing carriers each a set of 3 or 3 'is attached.
  • there the rotor associated set 3 is provided with narrow grinding strips 4, between which narrow grooves 6 are located.
  • the stator however, has a set 3 'with wide Mahlleisten 4 'and wide grooves 6'. This arrangement is one of the possible embodiments to view the invention.
  • FIG. 2 Another possibility is shown in FIG. 2, in which two sets of 3 " interact, whose working pages have essentially identical structures.
  • a set according to the invention is shown in plan view, which as a circular ring segment is designed over 90 °.
  • trimmings are in circular ring segments produced and assembled in the grinding machine to complete circular rings. They will screwed with the help of screw holes 7 with the clothing carrier.
  • the wide and narrow Mahlleisten summarized in groups 8 and 9 respectively. So this set contains a group 8 with wide Mahlleisten and a group 9 with narrow Milling strips.
  • wide and narrow can also be found on the clothing Grinding bars alternately alternate, as it is e.g. in Fig. 2 is shown in an example.
  • the Garnitur according to FIG. 3 is carried out in its entirety with parallel strips or grooves, which is the Production much easier and also at different knife angles on this Set leads.
  • group 10 An example with three groups 10, 11 and 12, each with different grinding bars, is shown in the figure Fig. 4.
  • the milling bars have a mean width, e.g. 4 mm and an angle ⁇ to the radius of about 35 ° in the middle.
  • Group 11 is provided with wide milling strips, e.g. 10 mm, designed and has a very shallow angle ⁇ '.
  • the third group 12 has about 2 mm narrow Mahlleisten and a mean angle ⁇ "of about 20 °.
