  1. Agencement de broyage pour broyer des fibres de cellulose en suspension aqueuse entre deux surfaces de broyage (2, 3) formant un interstice de broyage (1) et tournant l'une par rapport à l'autre, qui sont formées par des nervures de broyage (4) et des rainures (5) s'étendant entre elles, les nervures de broyage (4) s'étendant au moins avec la composante directionnelle principale radialement par rapport à l'axe de rotation (6), la distance de l'extrémité radialement interne de toutes les nervures de broyage (4) d'au moins à chaque fois une surface de broyage à l'axe de rotation (6) est différente d'au plus 10 % les unes par rapport aux autres, par rapport à la longueur maximale radiale des nervures de broyage (4), certaines des nervures de broyage (4) se divisant radialement vers l'extérieur et la distance entre les nervures de broyage (4) se divisant augmentant radialement vers l'extérieur de manière continue dans une portion divisée (9) suivant la division, caractérisé en ce qu'au moins l'une des nervures de broyage divisées (4) s'étend sous forme courbe après une portion divisée (9) suivant la division et la largeur des rainures (5) entre les nervures de broyage (4) à l'extérieur des portions divisées (9) suivant une division étant identique.
  2. Agencement de broyage selon la revendication 1,
    caractérisé en ce que l'extrémité radialement interne de toutes les nervures de broyage (4) d'au moins une surface de broyage (2, 3) est éloignée de la même distance de l'axe de rotation (6).
  3. Agencement de broyage selon la revendication 1 ou 2, caractérisé en ce que l'extrémité radialement interne de toutes les nervures de broyage (4) d'au moins une surface de broyage (2, 3) est éloignée d'une distance différente de l'axe de rotation.
  4. Agencement de broyage selon la revendication 3,
    caractérisé en ce que des nervures de broyage (4) moins éloignées de l'axe de rotation (6) alternent dans la direction périphérique avec des nervures de broyage (4) plus éloignées de l'axe de rotation (6) .
  5. Agencement de broyage selon l'une quelconque des revendications précédentes, caractérisé en ce que la division d'au moins certaines nervures de broyage (4) d'au moins une surface de broyage s'effectue à une distance différente à l'axe de rotation (6).
  6. Agencement de broyage selon la revendication 5,
    caractérisé en ce que la distance de la division à l'axe de rotation (6) dans la direction périphérique de la surface de broyage augmente en continu.
  7. Agencement de broyage selon l'une quelconque des revendications précédentes, caractérisé en ce que certaines nervures de broyage, de préférence toutes les nervures de broyage (4) sont à chaque fois divisées en deux nervures de broyage (4).
  8. Agencement de broyage selon la revendication 7,
    caractérisé en ce qu'après la division d'une nervure de broyage (4) et après une portion de division (9) suivant la division, à chaque fois seulement l'une des deux nervures de broyage divisées (4) s'étend sous forme courbe.
  9. Agencement de broyage selon la revendication 8,
    caractérisé en ce que la nervure de broyage courbe (4), après sa courbure, s'étend parallèlement aux deux nervures de broyage adjacentes (4).
  10. Agencement de broyage selon l'une quelconque des revendications précédentes, caractérisé en ce que la distance de l'extrémité radialement interne de toutes les nervures de broyage (4) des deux surfaces de broyage à l'axe de rotation (6) est différente d'au plus 10 % les unes par rapport aux autres, par rapport à la longueur maximale radiale des nervures de broyage, et certaines des nervures de broyage (4) se divisent radialement vers l'extérieur.
