  • the invention relates to the design in the area of a grate of a comminution machine, in particular for comminuting waste and valuable materials as well as ores, stones, coals and the like, the housing of which is provided with at least one material inlet and with at least one grate in the outlet area and one with comminution tools occupied rotor with a horizontal axis.
  • a crushing machine of the above type, but which is only intended for metal scrap, is described in DE-OS 22 25 916.
  • the design in the area of the grate or the grate arranged in the outlet area has an indirect or direct influence on the shredding result.
  • such machines are less well suited for the waste and recycling processing industries because the specific requirements placed on the quality of the end product, for example with regard to different piece sizes or degrees of fineness and / or. Densities can only be achieved by using different types of outlet grilles with variable grate openings be, which would have to be exchanged for adaptation to the desired final crushing result.
  • the object of the invention is to mechanize the conversion of the machine in a comminution machine of the type described in the introduction, for which the feed material is not intended to be limited to metal scrap, however, in order to largely avoid the disadvantages described above.
  • this object is achieved in that the grate (s) is or are made up of a plurality of active element-forming layers which can be displaced relative to one another.
  • the active elements can also consist of adjustable layers with holes of different sizes, where. a different hole geometry is also possible.
  • different hole geometries include, in particular, both different geometrical designs of the holes, such as round or square holes, as well as different hole arrangements understood.
  • the relative setting of the active elements to one another is preferably achieved in that the layers forming the active elements are either pivotally or displaceably mounted relative to one another. This measure ensures particularly practical handling and time-saving control of the adjustment of the active elements to one another without machine downtime and disassembly, it being advisable to provide a step-by-step, stroke-conscious adjustment.
  • the invention and the device according to the invention offer the possibility, in the view of the operating personnel, of showing or removing the comminution element required for the processing of the material being driven during operation of the machine.
  • easily crushable bark is fed to the device according to the invention, which does not require any special measures for shredding;
  • stronger branches and roots can be abandoned that cannot be easily shredded.
  • the operating personnel can set the machine according to the invention immediately during operation to the changed operating situation or by the patrix is shown, which then protrudes through the die openings, so that the branches or roots given an additional crushing effect, whereby the Processing is significantly intensified.
  • cooling scrap high-density scrap, which is added towards the end of the melting process to calm and / or cool batches
  • cooling scrap high-density scrap, which is added towards the end of the melting process to calm and / or cool batches
  • the crushing machine generally designated 1, has a housing 2, which stands on a base plate 3.
  • a comminuting rotor 4 rotates in the direction of rotation R, the shaft 5 of which is mounted on both sides in bearings (not shown) which are fastened to bearing blocks.
  • the rotor 4 consists of a plurality of rotor disks 6 lined up at a distance on the shaft 5, between which, in the exemplary embodiment shown in FIG. 1, only indicated cutting tools 7 are rotatably mounted on axes 8, which parallel the rotor disks 6 at a radial distance from the shaft 5 to enforce the latter.
  • the shaft 5 is connected to a drive via a clutch disc (not shown).
  • a good inlet 9 and good exits 10a and 10b are provided in the housing 2, which are provided.
  • the material inlet 9 is arranged on the downward rotating side of the comminution rotor 4 at the level of the horizontal plane H-H containing the rotor axis x.
  • the lower edge of the material inlet opening 9 is part of an exchangeable anvil 11.
  • the part of the housing 2 above the comminution rotor 4 is designed as an impact chute 12 open at the top and bottom, the height of which is approximately the diameter, for example of the comminution rotor 4 corresponds.
  • the baffle shaft 12 is covered with a classifying grate or outlet grate 13, which is provided with grate openings 14 and extends perpendicular to the axis of the baffle shaft 12.
  • the classifying or outlet grate 13 can be pivoted about an axis 16 by means of a hydraulic cylinder (not shown) Lich stored cover plate 15 are closed.
  • a hood 17 on which the material thrown out of the grate openings when the flap 15 is open is deflected downward and then passes through an opening 18 to the outside. Any coarse parts that can be crushed in the housing 2 can be ejected through a flap 19 which can be pivoted about an axis 20 into the impact shaft 12.
  • the second outlet 10a which is also rust-like and is arranged downstream of the material inlet 9 in the direction of rotation R of the rotor 4, is designed according to the invention as follows:
  • the circular-shaped housing part (s) 21 containing the grate (s) is or are in the exemplary embodiment shown constructed in the radial direction from a plurality of layers forming active elements 22, the active elements 22 in the exemplary embodiment shown being designed as interlocking dies 23 and dies 24 and being displaceable or pivotable relative to one another.
  • Preferred forms or designs of matrices or patrices according to the invention are described in more detail below.
  • gratings designed according to the invention can be arranged and provided at all points on the machine housing, e.g. in the housing base (as shown) as a cover for an outlet grate lying above the rotor or as a side outlet grate, for example in all spatial positions.
  • the die 23 and the patrix 24 are mounted so as to be pivotable about a common pivot axis 25.
  • Two hydraulic cylinders 26 - which are fastened on the one hand to the male part 24 and on the other hand to the housing 2 of the comminution machine 1 via articulated connections 27a and 27b - are used for opening, closing and / or blending, i.e. Projecting through or reaching through and pivoting the male 24 and / or female 23 into the various desired positions, each of which is required to adapt to the required piece size or fineness and / or density.
  • corresponding coupling elements 28 for example a screw connection shown in FIGS.
  • FIG. 1 bil detects the housing base 30 or the die 23 the housing part 21 of the comminution machine 1 containing the grate.
  • the male part 24 is in the pivoted-in state and engages in the die 23. In this way, a closed housing base 30 is created.
  • the active elements 22, here die 23 and / or male 24, can be exchanged relatively easily for other active elements 22.
  • the fastening elements 31 securing the swivel axis 25 and screwed to the die 23 and the fastening elements 32 by means of which the head 33 of the swivel axis 25 is fastened to the housing 2 are loosened. Then can the pivot axis 25 axially outwards up to the recess 34 in the housing? are pulled so that the die 23 can be freely replaced downwards.
  • the male part 24 is screwed onto a frame 24a, so that it can also be replaced at any time with any other male part without great effort, only by loosening the fastening elements or the screws 35 shown in FIG. 11, for example.
  • FIG. 4 shows, for example, a position of the active elements 22 in which maintenance work on the comminution machine can be carried out particularly well and possible material blockages can also be removed.
  • the male part 36 is designed in such a way that, as shown in FIG. 6, its protrusions extend or are pushed through the female part 37 and protrude beyond the inner surface 30 of the male part, then, for example, a grinding or tearing effect occurs with certain materials. or in the case of scrap, for example, a so-called "mattress effect", which protects the housing base 30 against wear.
  • the die holes 37a could be cleaned if the raised portions of the male part 36 were pierced briefly by the female part 37 and / or blockages were removed from easily clogged materials.
  • Fig. 7 shows an alternative die 39, in which the die holes 39a act as a stop by a corresponding design - preferably an essentially L-shaped longitudinal section.
  • the die holes 39a act as a stop by a corresponding design - preferably an essentially L-shaped longitudinal section.
  • the spacer is countersunk in the lower elongated hole 43 by correspondingly turning the screw cap 41 and thus the spacer 42, as a result of which the die 39 is lowered accordingly and the die 38 is pushed through the die holes 39a as shown in FIG. 9.
