Definitions

  • the present invention relates to a device for crushing various materials based on a hammer mill. This device is particularly suitable for comminuting large quantities of paper, cardboard, cardboard, etc.

  • This has on the outer sides of the adjacent counter-rotating shafts in each case a further wave, on which also comminution discs are arranged.
  • the comminution discs of the two outer shafts engage in an analogous manner in the respective adjacent inner waves and thus form next to the central main rupture of the central two waves two lateral Crowerißtechnike.
  • Below the four waves is a corresponding curved sieve arch.
  • the shredded by the mean Hauptr complicattechnik materials are transported to the forming the lateral Mauerißtechnike waves and further reduced by these until they are so small that they can fall through the sieve openings and can be collected below.
  • In the WO 93/14874 is such device by applying ring segments on the crushing elements and equipped with fangs to improve the crushing effect further optimized.
  • devices that have only one crushing roller are known for crushing materials, such as from EP 0 908 238 A1 .
  • the comminution is carried out by the fact that stand up from the circumference of the crushing roller cutting teeth, which cooperate with a fixed counter-knife arranged above it.
  • the material to be comminuted is transported to the gap between the blade and the counter-blade, and then cut during the passage of the gap.
  • crushing paper usually produces very small pieces, depending on the sieve that may be used.
  • the pressing to bales, which can be well stored in both large quantities and transport well, but with the resulting very small pieces of paper is difficult, as they separate more and more of the bale compound and the bale over time more uneven and becomes more unstable.
  • US 4,134,554 B is a hammer mill is known in which frequent blocking is avoided as a result of uneven paper feed with the aid of an adjustable grate.
  • a sensor detects when the roller locks and causes the power to the roller drive motor to stop and raise the grate. In this way, the paper is moved away from the roll and reduces the pressure that the paper causes on the roll. The roller can then run freely again at normal speed.
  • the present invention was therefore based on the object to provide a device or a method that no longer has the above-mentioned disadvantages of the prior art.
  • the device or method should be suitable for use with various materials, i.a. Even paper to crush, without the comminution devices jamming, or that the material to be crushed during comminution receives such a consistency that further processing is difficult.

Due to the rotational movement of the roller, which is reversing at regular intervals, the sidepieces should preferably be mounted in mirror-symmetrical fashion so that the same effect is also produced in the opposite direction.

  • the minimum distance of the ribs of the grate (7) to the longitudinal axis of the roller is infinitely or stepwise, preferably continuously variable. It is particularly advantageous to control the variation of the said length of the vertical in the course of the comminution process via the control unit, since this length also controls the supply of the material to be reduced and thus the resistance presented to the hammers.

  14. Procédé selon la revendication 13, caractérisé en ce que le broyage est effectué par déchiquetage.
  15. Procédé selon la revendication 13 ou 14, caractérisé en ce que la vitesse de rotation du cylindre (4), la puissance du cylindre (4), la distance minimale des rebords de la grille (7) par rapport à l'axe longitudinal du cylindre (4), l'acheminement du matériau à broyer et/ou le parachèvement du matériau broyé sont commandés électroniquement.
