Definitions

  • the invention relates to an impact mill for crushing fine chips, from Finest chips, powder or flour from a feed.
  • the Feed material consists, for example, of shavings or sawdust, Knife ring shavings, knife shavings, shavings from used wood or from residual wood, annual plants, shredded waste paper and all sorts other substances that are to be crushed.
  • impact finisher MPF from B. Maier Zerkleintechnikstechnik GmbH, printed note 217 / 3-93 referred.
  • the crushing work of such impact mills is between in the work area Baffle bars of the rotor and a so-called grinding track.
  • the Grinding track is part of the housing.
  • the to the work space adjacent components are subject to relatively high wear. This is especially high for the baffle strips on the outer circumference of the rotor are attached. That is why it is necessary to replace the bumper strips frequently.
  • Removing worn bumpers and installing new bumpers is extremely time consuming and cumbersome. It requires a complete one Removing the rotor. Removing the rotor not only causes Personnel expenses, but also a loss of production as a result of The mill stops.
  • the invention has for its object an impact mill according to the To design the preamble of claim 1 such that the exchange worn bumper bars against new bumper bars faster and easier has been going on ever since.
  • the impact mill shown in FIG. 1 has a rotor 1. This is from enclosed a grinding track 2.
  • the grinding track 2 is on a housing 3 fixed stationary.
  • the housing 3 has an inlet 3.1 and one Outlet 3.2 on.
  • the rotor is mounted in the housing 3 by means of a shaft 1.1. It comprises two Discs 1.2, 1.3. These bear a variety of on their outer circumference Support plates 1.4. A baffle bar 3.5 is attached to each support plate. The Details of the design of the support plate 1.4 and baffle bar 1.5 result from FIGS. 2 to 4.
  • Each support plate has a number of rivets 1.6 of the same number Elongated holes 1.7, which have the shape of keyholes - see Figure 2.
  • a locking plate 1.8 pivoted or shifted so that there is a lock between Rivet 1.6 and support plate 1.4.
  • the locking plate 1.8 is by means of of a special tool pivoted or shifted, the one hand on the Support plate 1.4 and on the other hand on a crank 1.8.1 Tab washer attacks.
  • Support plate 1.4 In the embodiment according to FIG. 5, one can again be seen Support plate 1.4.
  • a blow bar 2 and a clamping bar 3 can also be seen, which are arranged on both sides of the support plate 1.4.
  • the blow bar is here fixed by a screw connection, comprising a screw 4 and a bolt 5 with an internal thread.
