Definitions

  • the invention relates to a hammer crusher, whose at least one rotor by at least one club disc is formed on which - over its circumference regularly distributed - hammers are arranged, with each percussion hammer around one Holding pin is freely rotatable within a resonant space.
  • the hammer crushers can have multiple rotors and can on each rotor several racquet discs are arranged one behind the other.
  • hammer crushers of the aforementioned type are in particular such hammer crushers to understand, whose disc diameter between 1600 and 2400 mm is.
  • document DE-C2-2713177 describes a hammer crusher having five Impact hammers. However, the latter are not within each one of their own Chest space arranged so that no targeted crushing effect and Material management can be achieved with the participation of each associated resonant space.
  • the invention has for its object to form a hammer crusher such that it does not have the aforementioned disadvantages of the prior art.
  • the object is achieved by a hammer crusher with the features of the claim solved with the result that the difference between the diameter of the rotor and the Diameter of the club disks - and thus the hammer overhang - if possible can be chosen large and that the vibration chambers for the impact hammers a As small as possible distance from each other.
  • the large hammer projection allows the cross section of the impact hammers To carry out much larger than is possible in the known hammer crushers. Due to the resulting high moment of inertia around the respective The axis of the respective retaining bolts is the refractive power of the individual impact hammers significantly increased. In addition, the impact hammers are also larger Stone pieces are better crushed, for example, by large rocks much larger parts knocked off than with the known hammer crushers was possible. The aforementioned improvements in the inventive Hammer crushers lead to a much higher material throughput compared to the known hammer crushers.
  • the axis of the rotor By forming the axis of the rotor with a pentagonal cross-section - where the faces of the pentagon of the axis facing the swinging spaces of the impact hammers are - receives the rotor axis an optimal area moment of inertia.
  • a rotor I of a hammer crusher represented, on whose successively arranged whip disks 2 on the circumference regularly distributed in each case five impact hammers 3 are hinged. Every hammer 3 is over a retaining pin 4 within a resonant space 5, which is slightly larger than that Oscillation 6 of the hammers 3 is free to rotate.
  • the difference between the diameter DR of the rotor 1 and the diameter DS the club discs 2 is chosen as large as possible, so that a relatively large hammer supernatant HÜ yields. This is achieved on the one hand, that the Resonant spaces 5 have the smallest possible distance from each other while on the other hand, the diameter DS of the whipper disks 2 only by such a degree greater than the diameter DT of the pitch circle 7, on which the retaining bolts 4 for the Impact hammers 3 are arranged so that the retaining bolts 4 in the bathlesses. 2 are kept sufficiently secure.
  • the axis 8 of the rotor 1 has a pentagonal cross-section, wherein the surfaces of the pentagon are each facing the vibration chambers 5.
