Description

  

      lfalilsclieibeiipaar    mit ebenen     Nahtflächen.       Die Erfindung     betrifft    ein     Mahlscheiben-          paar    mit ebenen Mahlflächen, auf welchen       tangential    zu einem     innern    Kreis laufende       f.uftfurehen    vorgesehen sind.

   Das Wesen  der Erfindung besteht darin, dass jede der       h(-iden        Mahlscheiben    zwischen den     Luftfur-          chen    mehrere, zu dem     innern    Kreis in kon  zentrisch laufenden Kreisen angeordnete,       zonenweise    von     innen    nach aussen feiner     wer-          ilend(#    Riffeln besitzt.

   Diese Riffeln sind       zw(-ckmä        ssig    so in die Mahlscheiben eingear  beitet, dass     erstere    Schneide auf Schneide     ar-          be        it(#rr.     



  Man verhindert durch diese Ausbildung  der     Hahlscheiben    ein     Verschmieren    der       :flahlflä,chen,    weil der Mahlvorgang stufen  förmig stattfindet. Ausserdem wird der       Kra.ftverbrauclr    für den Antrieb des Mahl  scheibenpaares     auf.    ein Mindestmass herab  gedrückt, da die Riffeln der innern, ersten       Znne    etwas schärfer ausgeschnitten sind als  die Riffeln der letzten,     äussern    Zone.  



  Durch die parallele Lage der Mahlflä  chen zueinander, sowie durch die stufen  förmig angeordnete und Schneide auf       @@lrrreide    arbeitende Riffelung findet von    vornherein eine intensive     Vermahlung    reit:  derartig hoher Mehlbildung statt, dass die  letzte, verhältnismässig schmale Zone nur  noch geringe Arbeit zu verrichten hat.  



  Die erzielte     Verbesserung    wirkt sich im  ganzen dahin aus, dass das in beschriebener  Weise ausgebildete     Mahlscheibenpaar    bei  höchster Leistungsfähigkeit einen verhältnis  mässig geringen     Kraftverbrauch    hat.  



  Eine Mahlscheibe mit gemäss der Erfin  dung ausgebildeter Riffelung     ist-    auf der     1)"i-          liegenden    Zeichnung dargestellt.  



       Fig.    1 zeigt eine der beiden Mahlscheiben  mit der neuen Schärfe.  



  Die Luftfurchen a sind     tangential    zu  einem innern     greise    verlaufend angeordnet.  Die von innen nach aussen hin feiner wer  denden Riffeln b laufen "parallel zu den  Luftfurchen a..  



       Fig.        \?    zeigt einen Schnitt     x-x,    der die       Riffelform    erkennen     lä,sst.  



      lfalilsclieibeiipaar with flat seam surfaces. The invention relates to a pair of grinding disks with flat grinding surfaces, on which there are provided air conveyors running tangentially to an inner circle.

   The essence of the invention is that each of the h (-id grinding disks between the air grooves has several corrugations that are arranged in concentric circles with respect to the inner circle and become finer in zones from the inside to the outside (# corrugations.

   These corrugations are worked into the grinding disks in such a way that the first edge works on edge (#rr.



  This design of the hollow disks prevents the flahlflä, chen from smearing because the grinding process takes place in stages. In addition, the power consumption for driving the grinding disk pair is opened. pressed down to a minimum, since the corrugations of the inner, first teeth are cut out somewhat sharper than the corrugations of the last, outer zone.



  Due to the parallel position of the grinding surfaces to one another, as well as the stepped corrugation that works on the cutting edge, intensive grinding takes place from the outset: flour is so high that the last, relatively narrow zone only has to do little work .



  The overall effect of the improvement achieved is that the pair of grinding disks designed in the manner described has a relatively low power consumption with the highest performance.



  A grinding disk with corrugation formed according to the invention is shown on the drawing lying on the 1) "i.



       Fig. 1 shows one of the two grinding disks with the new sharpness.



  The air furrows a are arranged to run tangentially to an inner age. The corrugations b, which become finer from the inside outwards, run "parallel to the air furrows a ..



       Fig. \? shows a section x-x, which reveals the corrugated shape.
