Furthermore, in the tenth embodiment, the left and right cutting blades 277 A, 277 B have different configurations, and the left and right cutting blades 277 A and 277 B have different configurations. The distances of the crushed objects may be made different from each other to obtain crushed objects of different sizes with the same crushed object 320. These combinations may be determined according to the type of the crushed material 320, crushing conditions, and the like.
  • Fig. 18 is a time chart showing an example of controlling the rotation speed of the rotating shaft in a shearing type crusher.
  • the material to be crushed 320 from the inlet is cut into the cutting blades 7, 37, 67, 97, 127, 157, 187, 217, 247 , 277, and crushing multiple times while feeding in the lateral direction, the crusher body 1, 31, 6, 91, 91, 121, 151, 181, It becomes impossible to install a scraper on the side of 2 1 1, 2 4 1, 2 7 1 to remove the crushed material attached to the cutting blade.
  • the crushed material 3 20 attached to the cutting blade 7, 37, 67, 97, 127, 157, 187, 187, 247, 277 is cut.
  • the blade 7, 37, 67, 97, 127, 157, 187, 217, 2477, 27 7 May remain.
  • soft crushed material 32 such as a vinyl rope can be used for cutting blades 7, 37, 67, 97, 127, 157, 187, 217, When it is wound around 247 and 277, it may not be able to be removed. If such a material to be crushed 320 adheres to the blade portion (20), the crushing effect may be drastically reduced.
  • the cutting blades 7, 37, 67, 97, 127, 157, 187, 217, 247, and 277 are large. Due to excessive resistance, the cutting blade may generate heat and the crushed material 320 may be melted and adhered. In this case, the crushing effect may be significantly reduced.
  • both rotating shafts 2, 3, and Driving devices 5, 6, 35, and 6 are provided to drive 32, 33 independently, respectively, and as shown in the time chart of Fig. 18, each rotating shaft 2, 3, 3, 2, 3 3 If it is configured to rotate independently at different rotation speeds, the rotation speeds of both rotating shafts 2, 3, 3, 32, and 33 will be reduced even if the material to be shredded 320 is entangled with the cutting blades 7, 37. By changing it, the entangled crushed material 320 can be removed. Moreover, as shown in this time chart, the rotation speed of each of the rotating shafts 2, 3, 32, 33 is changed between high speed and low speed, and the high speed and low speed are alternately changed. By controlling the crushed material, the entangled crushed material 320 can be more reliably removed. This is possible in all the embodiments described above.
  • both rotating shafts 2, 3, 32, 33 are changed in rotational speed, and both rotating shafts 2, 3, 32, 33 are alternately driven at high speed and low speed at predetermined intervals.
  • the function is provided in the control device provided in the crusher.
  • first to tenth embodiments are merely examples, and various modifications can be made without departing from the gist of the present invention, and the present invention is not limited to the first to tenth embodiments. However, the present invention is not limited to this.
  • the crushed object to be sheared by the cutting blade can be repeatedly crushed in the crusher body a plurality of times, so that the crushed size of the crushed object can be reduced, and the installation space can be reduced. It is useful as a shear-type crusher when you want to crush the crushed material finely without causing an increase.

Abstract

Deux arbres rotatifs (2, 3) pour supporter un couteau latéralement dans un corps de broyeur (1) sont disposes parallèlement et des couteaux (7) chacun munis d'une pluralité de parties saillantes coupantes sur la circonférence externe sont disposés dans la direction axiale de ces deux arbres rotatifs (2, 3) de sorte que les parties coupantes s'engagent entre elles. Une ouverture (9) pour charger un article à broyer (320) est ménagée dans la partie supérieure du corps broyeur (1) à une extrémité axiale de l'arbre rotatif et une ouverture (10) pour décharger l'article broyé (320) est faite dans la partie inférieure du corps broyeur (1) à l'autre extrémité axiale de l'arbre rotatif. L'article à broyer (320) est broyé plusieurs fois dans le corps broyeur (1) en prévoyant un organe latéral d'alimentation (14) pour alimenter l'article à broyer (320), chargé par l'ouverture (9) et broyé par les couteaux (7), en direction de l'ouverture de décharge (310).
