Definitions

  • the invention relates to an impact mill according to the preamble of claim 1.
  • Such mills are used in particular in the stone and earth industry.
  • Rocks, ores and the like are extracted by means of hammer and impact mechanisms with hammers or blow bars attached to the rotor. roughly crushed. Precrushing takes place conventionally in an impact chamber in front of and above the rotor, while post-shredding takes place between a grinding path and the orbit of the blow bars.
  • the desired grain size of the end product can be influenced within certain limits by adjusting the grinding gap.
  • the subsequent outlet is usually arranged vertically below the rotor.
  • the shredded material is ejected in a more or less large arc as it exits the machine, depending on the mass.
  • a catch box has been installed under the outlet in stationary systems, which holds a buffer of shredded material.
  • a crusher according to DE-OS 24 24 170 is typical of such systems.
  • a U-shaped housing is preceded by an oblique inlet and a grille is arranged downstream of the outlet.
  • An upper kinked wall covers the chamber above the rotor with inlet and outlet.
  • the undersides of the inlet and outlet form a falling tangent to the rotor.
  • a conveyor belt can be arranged under the outlet, but there is relatively little space for this. Because the inlet is located at the opposite end, it builds Mill very wide. The crushing is done only by the impact effect, the grain gradation is hardly adjustable.
  • a high proportion of oversize particles also runs through, so that it is necessary to feed it to further comminution machines.
  • the inlet and outlet channels are separated from one another by a baffle boundary, on which, according to claim 3, a wiper baffle, in particular adjustable towards the rotor, can be arranged.
  • a wiper baffle in particular adjustable towards the rotor.
  • an oblique support can lead to the outlet channel according to claim 10, which may be e.g. is adjustable by means of claims 11 and 12 and allows the direction and size of the outlet channel to be changed as required.
  • the narrow path adjoining the inlet impact space at the bottom can be pivoted — as is known per se — according to claims 13 and 14, specifically about an axis located above the rotor shaft.
  • the impact mill designated as a whole by 10, has a housing 12, the bottom 14 of which, in the stationary version, is arranged about 1.5 m above the ground.
  • a rotor 16 arranged in the lower part of the housing 12 is mounted horizontally and has percussion strips 18 on the circumference, which can be arranged somewhat eccentrically with respect to the rotor shaft 56.
  • the orbit 19 of the outer blow bar contour is shown in dashed lines in FIG. 1.
  • the housing 12 has an inlet impact chamber 20 with an inlet opening 22, in front of which a lattice work in the form of a chain link curtain 24 can be arranged.
  • the inlet impact space 20 has a boundary 25 at the bottom.
  • the inside of the impact chamber is provided with wear armor 26, which continues at the bottom on a grinding track 28.
  • a pressure cylinder 58 can be present, the piston 60 of which is articulated on the lower part of the grinding track 28.
  • At its lowest point is the lower boundary 32 of an outlet channel 30, which is directed obliquely upwards and leads under the inlet opening 22 of the inlet 20.
  • the lower limit 32 bends into a downwardly extending guide surface 34.
  • the impingement boundary 25 which carries a wiper impact surface 36 in the outlet channel 30 at the lower end. This can be adjusted essentially radially to the rotor 16 or the rotor shaft 56 by means of an adjusting device 38 if wear occurs on the blow bars 18, which reduces the diameter of the orbit 19.
  • a discharge box 40 adjoins the outlet duct 30, which has an inclined wall 41, a platform 44 and a vertical baffle wall 42. These changes are also preferably provided with wear armor.
  • the actuating device 38 can be actuated from the platform 44; it consists in particular of two threaded rods with a guide at the lower end, but it is also contemplated according to the invention to use at least one pressure cylinder for adjusting the wiper baffle 36 for sensitive adjustment.
  • outlet edge 33 in the outlet channel 30 is set back relative to the fillet 45, which is formed between the inclined wall 41 and the platform 44. This ensures that the outlet channel 30 extends continuously into the discharge box 40, so that the discharge material is neither tilted nor squeezed and can slide freely on the vertical baffle 42 onto a conveyor belt (not shown).
  • a bottom flap 52 is arranged at the lowest point of the lower boundary 32 of the outlet channel 30. That’s it possible to quickly and conveniently remove a material buffer 50 forming at the lower end of the grinding track 28, if necessary.
  • the invention also provides that large parts of the lower limit 32 can be removed, so that the entire lower space can fill up to the bottom 14 of the housing 12 with deposited regrind.
  • Such an extended material buffer 50 is delimited towards the discharge side by an oblique support 46, which can be designed as a telescope arrangement or can be provided with suitable, optionally adjustable supports.
  • a joint or an axis of rotation 62 is provided on the lower boundary 32, so that when using (not shown) adjusting devices such as pressure cylinders or the like. a change in the clear width of the outlet channel 30 and the discharge gap 48 can be made.
  • the material is conveyed past the buffer 50 by the blow bars 18 of the rotor 16 into the outlet channel 30 and further into the discharge box 40, from where it flows downward.
  • the impact seat 10 is arranged on a crawler track 64.
  • the structure is essentially the same as that described above, but the overall height is even smaller because the lowering of the housing 12 between the crawlers of the undercarriage 64 results in a ground clearance b of e.g. 0.4 to 0.5 m is sufficient.
  • a screening machine (not shown) can be connected to the impact mill 10 according to the invention, which is expediently attached below the discharge box 40 and for screening out the oversize particles against the feed material flow, i.e. away from the machine, works.
