Definitions

  • a spin mill according to the preamble of Claim 1 is known from US-A-4,738,403.
  • this movement phase ends when the particle 16 on the Ground material bed 26 hits, which occurs when the spinning blade is rotated 24 forms in front of this and the blade wall 28 protects against wear.
  • the particle 16 is braked in the case of catchment and his Relative speed with respect to the centrifugal blade 24 is zero reduced.
  • a pre-crushing of the particle 16 instead of.
  • the particle 16 or its fragments is longitudinal the surface 26 a of the material bed 26 accelerated radially outward until he at the trailing edge 30 of the centrifugal blade 24 at point C the rotor 14 leaves and is accelerated to the baffle 20.
  • On impact against the Baffle 20 is the main crushing of the particle 16th

    l'arête d'extrémité (28b) intérieure radialement de chaque paroi d'ailette (28) des deux ailettes centrifuges (24) est disposée, lorsqu'on relie leurs deux arêtes d'arrachage (30) entre elles et on trace la médiatrice (M) sur cette ligne de liaison (V), respectivement, en partant de l'arête d'extrémité (28a) extérieure radialement de la paroi d'ailette (28), dans une plage angulaire d'environ 20° avant la médiatrice (M) jusqu'à environ 20° après la médiatrice (M).
  2. Broyeur centrifuge selon la revendication 1,
    caractérisé en ce que l'arête d'extrémité (28b) intérieure radialement de chaque paroi d'ailette (28) est disposée à une distance radiale (d) de l'axe de rotation (X), qui représente au moins environ 30 %, de préférence au moins environ 40 %, de la distance radiale de l'arête d'arrachage (30) de l'ailette centrifuge (24) à l'axe de rotation (X).
  3. Broyeur centrifuge selon l'une des revendications 1 à 2,
    caractérisé en ce que les surfaces (28d) convexes des parois d'ailette (28) forment la surface extérieure du rotor du broyeur centrifuge (14).
  4. Broyeur centrifuge selon l'une des revendications 1 à 3,
    caractérisé en ce qu'à proximité de l'arête d'arrachage (30), au-dessus et/ou au-dessous de l'ouverture de sortie de l'ouverture correspondante de la matière à broyer (52) du rotor du moulin broyeur (14), sont prévus des éléments de choc (50) avec des surfaces de choc (50a) dirigées de préférence sensiblement perpendiculairement au sens périphérique, lesquelles sont fabriquées de préférence dans un matériau présentant une faible usure.
  5. Broyeur centrifuge selon l'une des revendications 1 à 4,
    caractérisé en ce que des éléments d'usure (46) sont prévus sur les arêtes d'extrémité (28b) intérieures radialement des parois d'ailette (28).
