Definitions

  • the present invention relates to improvements vertical shredders.
  • a vertical crusher consists of a drive shaft on which are keyed discs having at their periphery articulated hammers, this assembly being housed in an enclosure cylindrical, the lateral part of which consists of a grid, the products to be ground being introduced at the top of said pregnant.
  • the device described in this document does not, in particular, compensate, in a satisfactory manner, the wear of the hammers so as to that this has no influence on the particle size.
  • the present invention which remedies these drawbacks, relates a grinder comprising a grid in the form of a cylindrical shell which can be moved axially relative to the axis hammer drive, said crusher being characterized in that the grid consists of a ferrule without perforation in its part upper and having perforations at its lower part, the grain size adjustment by moving the bottom edge of the grid in relation to the hammers.
  • the crusher has a first grid in the form of a ferrule cylindrical which can be moved axially relative to the axis of the hammers, and it is characterized in that it comprises a second grid, the two grids being coaxial and superimposed and having different characteristics, the grain size adjustment being carried out by moving the lower edge of the assembly, formed by the two grids, compared to hammers.
  • the grinder is consisting of discs 1, driven by a shaft 2 with a vertical axis, each of said discs comprising hammers 3 at its periphery.
  • This set is arranged in a delimited enclosure, laterally, by a cylindrical grid 4, at the bottom, by a bottom 5 and, above, by the lower part 6 of a loading hopper 7.
  • the mill is completed by a cylindrical ferrule 8 spanning between its face internal and the grid 4 an annular space 9 for recovering grinds.
  • the products to be ground are introduced from above and are subjected to the action of the first stage of hammers. As a result of this action, a certain part of the product passes through the grid 4 while the rest is taken up by the lower stage of the mill and so on.
  • the result obtained depends on a certain number of parameters such as: the grid mesh dimensions, the distance from the end of the hammers, the number of hammer stages and their rotational speed. he So it turns out that the only parameter on which it is easy to act is the speed of rotation of the hammers. Experience has shown that this adjustment was insufficient given the different situations that the grinder is used.
  • the grid 4 which is in the form a cylindrical shell, can be moved along the axis of the shaft 2 hammer drive.
  • the grid 4 is maintained by two rings 10 joined by columns 11 comprising, of preferably, the aforementioned guide members.
  • Figure 2 shows the position of the movable grid of the invention for a product and a given particle size.
  • the term "grain size" is not entirely correct because in many many cases what is sought is an end product with a certain percentage of very fine grains compared to a average particle size.
  • the grid 4 will be located towards the the higher the percentage of very fine grains will be low and Conversely.
  • the crusher can include two grids 4 and 4a as shown in FIG. 2.
  • the grid 4a has perforations whose dimensions are different from those in grid 4.
  • the characteristics of the grid 4a are different from those in grid 4.
  • the diameter of the grid 4a is different from that of grid 4. This characteristic which makes it possible to cooperate in adjusting the particle size allows also to compensate for the wear of the hammers and to reduce the time intervention on these.
  • the grid 4a is used; after a certain wear, grid 4 is used.
  • the mesh dimensions of the two grids are, from preferably identical.
  • the crusher of the invention can have more than two grids mobile.
  • the same grid can present different diameters.
