  • Devices which have only one comminuting roller are also known for comminuting materials, for example 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.
  • 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.

  • the materials to be comminuted are comminuted to a size which makes it possible to convert the comminuted material into a readily storable and / or transportable form.
  • the outlet opening is preferably located directly under the roller. If this makes sense, however, it can also be attached laterally, in which case of course it must be ensured by means of apparatus that the shredded material also reaches the lateral outlet opening.

  • the roller is controlled by a control device so that it reverses its direction of rotation periodically, and the cycle time, the speed and the drive power are adjusted depending on the material to be crushed.
  • This not only prevents the hammers from getting stuck in the crushing operation, but at the same time reduces the power to be applied from the material chopping roll because the material to be shredded on the roll is loosened by the reverse movement, thereby facilitating the crushing operation.

  • the shape of the first hammers is generally not limited, but it has been found that these are particularly effective when the front surfaces and back surfaces of the first hammers are significantly smaller than their side surfaces. Particularly advantageously, the side surfaces of the first hammers are flat and parallel to the cross-sectional plane of the roller.
  • the side surfaces of the first hammers seen in the direction of the roll longitudinal axis on the two longitudinal sides waistings. This facilitates the fixation of the material to be comminuted in the rotating movement of the roller in the recess formed thereby, similar to a paddle wheel, and thus simultaneously facilitates the comminution process.
  • the one allow such fixation of the material to be shredded during transport to Zerr alonestelle. 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.
  • additional counter-holders for example on the grate, can be attached, which also serve to fix the material during the comminution process or during transport to the comminuting point. This is all the less necessary, the heavier the material or the greater the amount filled.

  • 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.
