Definitions

  • the invention relates to a hammer crusher, the at least one rotor of which is formed by at least one beater disk, on which - regularly distributed over its circumference - impact hammers are arranged, each impact hammer being freely rotatable about a retaining bolt within a vibration chamber.
  • the hammer breakers can have a plurality of rotors and a plurality of beater discs can be arranged one behind the other on each rotor.
  • Hammer breakers of the aforementioned type are to be understood in particular as those hammer breakers whose disc diameter is between 1600 and 2400 mm.
  • the invention has for its object to design a hammer crusher such that it does not have the aforementioned disadvantages of the known hammer crusher.
  • the large hammer projection makes it possible to make the cross section of the impact hammers much larger than is possible with the known hammer breakers.
  • the resulting high moment of inertia about the respective axis of the holding bolts in question significantly increases the breaking effect of the individual impact hammers.
  • larger pieces of rock are crushed better by the impact hammers, for example large pieces of rock are chipped off much larger pieces than was possible with the known hammer breakers.
  • the aforementioned improvements in the hammer crusher according to the invention lead to a substantially higher material throughput than the known hammer crusher.
  • the axis of the rotor has a pentagonal cross section, the surfaces of the pentagon of the axis facing the vibration chambers of the impact hammers. This gives the axis of the rotor an optimal area moment of inertia.
  • a rotor 1 of a hammer crusher is shown, arranged one behind the other Racket disks 2 are regularly distributed over the circumference of each five impact hammers 3.
  • Each percussion hammer 3 can be freely rotated about a holding pin 4 within an oscillating space 5, which is slightly larger than the oscillating circuit 6 of the percussion hammers 3.
  • the difference between the diameter DR of the rotor 1 and the diameter DS of the club discs 2 is chosen to be as large as possible, so that there is a relatively large hammer overhang HÜ. This is achieved on the one hand by the fact that the vibrating spaces 5 are as close as possible to one another, while on the other hand the diameter DS of the beater discs 2 is only larger by such a dimension than the diameter DT of the pitch circle 7 on which the retaining bolts 4 for the percussion hammers 3 are arranged are so that the retaining bolts 4 are held sufficiently securely in the club discs 2.
  • the axis 8 of the rotor 1 has a pentagonal cross section, the surfaces of the pentagon each facing the oscillation chambers 5.

Abstract

L'invention concerne un concasseur à marteaux articulés dont au moins un rotor (1) est formé par au moins un disque de frappe (2) sur le pourtour duquel sont répartis de manière uniforme des marteaux (3). Chaque marteau (3) peut tourner librement autour d'un boulon de retenue (4) dans une chambre d'oscillation (5). A cet effet, il est prévu sur chaque disque de frappe (2) dans chaque cas cinq marteaux (3); la différence retenue entre le diamètre (DR) du rotor (1) et le diamètre (DS) des disques de frappe (2) et par conséquent l'extrémité en porte-à-faux (HU) du marteau est la plus grande possible; les chambres d'oscillation (5) prévues pour les marteaux (3) présentent un écart aussi réduit que possible entre elles.
