Description

  

  verfahren zur Herstellung eines Düngemittels.    Das den     Erfindungsgegenstand    bildende       Verfahren    zur Herstellung eines     Dü geinittels     beruht darauf, dass     inan    rohen     Kalkuiergel     einer     deichmüssigen        Durchglühung    unter re  duziertem 'Luge bis zur Bindung einer     Kruste     aus Ätzkalk unterzieht und mit aus denn  gleichen Kalkmergel gar     gebranntem    Kalk nach  der     Feinmahlung    beider     unter    mindestens an  nähernd gleiche  Volumenverhältnissen mischt.  



  Dadurch wird ein Kalkdünger erhalten,  welcher eine regelmässige     Hydratisation    des  Bodens ohne     Auftreten    der bei der bisherigen  reinen Ätzkalk- oder Kalk- und     Kalkst.Pin-          düngung    her bekannten Verbrennungserschei  nungen bewirkt, welch letztere den Wert der  Kalkdüngung meist aufhoben.  



  Bei     dein    neuen Düngemittel wird durch  die starke     Volumenvergrösserung    bei der  Wasseraufnahme und der dabei     8tattfi dein-          den    Tempel      < atursteigerung    eine kräftige Locke  rung und     Erwärinu g    des Bodens erzielt, so  wie eine allmähliche, molekular fortschreitende  Lösung der Teilchen des     Kalkmergels    durch  die Teilchen des gebrannten Kalkes hervor  gerufen,

   so dass das Düngemittel auch     i     che  mischer Hinsicht     gleichmüssiger        und    anlial-         tender    auf den     Boden    einwirkt als eine     bis-          lier        angewandte        3lischu g    von     Kalkstein    und       gebranntem        Kalk.     



  Bei der     praktischen        Ausführung    des neuen  Verfahrens erfolgt das Durchglühen des rohen  Kalkmergels bis zur Bildung einer     Atzka.lk-          krust.e    am     rationellsten        i         Drelirohi@lifen    unter  reduziertem Feier, das Brennen des     Kalk-          mergels        zii    Kalk in     gewöhnlichen        Kalküfen.     Das     Mahle     beider Bestandteile geschieht  bis auf 500 Maschen Feinheit.



  process for the production of a fertilizer. The method for the production of a fertilizer, which forms the subject of the invention, is based on the fact that inan raw calculating gel is subjected to dike-like annealing under reduced lime until a crust of quick lime is bonded and, with the same lime marl, even burnt lime after fine grinding both under at least approximate mixes equal volume ratios.



  In this way, a lime fertilizer is obtained, which causes a regular hydration of the soil without the occurrence of the combustion phenomena known from the previous pure quicklime or lime and limestone fertilization, the latter mostly canceling out the value of the lime fertilization.



  With your new fertilizer, the strong increase in volume when absorbing water and the increase in the size of the temple at the same time result in a strong loosening and warming of the soil, as well as a gradual, molecularly progressive dissolution of the particles of the calcareous marl by the particles of the burnt Summoned lime,

   so that the fertilizer has a more even and more uniform effect on the soil from a chemical point of view than a previously used mixture of limestone and quick lime.



  In the practical implementation of the new process, the raw calcareous marl is burned through until an atzka.lk- krust.e is formed, which is most rationally done i Drelirohi @ lifen with reduced celebration, the calcareous marl is burned to lime in ordinary calcuins. Both components are ground down to a fineness of 500 meshes.
