Description
<Desc/Clms Page number 1>
Verfahren zur Herstellung von künstlichen Mühlsteinen.
Den Gegenstand der Erfindung bildet die Herstellung künstlicher Mühlsteine aus Schmirgel, Granit oder Quarz mit Magnesit und Chlormagnesia als Bindemittel und einem die Porosität dauernd sichernden Füllstoffe. Als poröser Füllstoff wird erfindungsgemäss zerkleinertes Hollundermark verwendet, während bisher Sägespäne und Korkmehl für diesen Zweck benutzt worden sind. Gegenüber diesen bekannten Füllstoffen weist Hollundermark die Eigentümlichkeit auf, dass es sich von der einschliessenden Wandung sehr leicht loslöst. Wird infolge Abnutzung des Steines eine von Hollundermark ausgefüllte Höhlung geöffnet, dann springt das darin enthaltene Hollundermarkteilchen als Ganzes heraus.
Hierdurch wird die Schleiffähigkeit der Steinoberfläche dauernd gewährleistet und es tritt das sonst so lästige Verschmieren des Steines nicht ein.

Process for the production of artificial millstones.
The subject of the invention is the production of artificial millstones from emery, granite or quartz with magnesite and chloromagnesia as binders and a filler that permanently secures the porosity. According to the invention, crushed elderberry pulp is used as the porous filler, while sawdust and cork flour have previously been used for this purpose. Compared to these known fillers, elder marrow has the peculiarity that it detaches itself very easily from the enclosing wall. If, as a result of the wear and tear of the stone, a cavity filled with elder marrow is opened, the elderly marrow particle contained therein pops out as a whole.
This ensures the ability of the stone surface to be sharpened and the otherwise annoying smearing of the stone does not occur.
