Description

Mahlstein für Farbmühlen zum Aufarbeiten von Farbhäuten Die Erfindung bezieht sich auf einen Mahlstein für Farbmühlen zum Aufarbeiten von Farbhäuten, wie sie vorzugsweise in Malerwerkstätten verwendet werden.Millstone for paint mills for processing paint skins The invention refers to a grinding stone for paint mills for processing paint skins, as they are preferably used in painting workshops.

Anders als in Farbenfabriken ist die in Malerwerkstätten zum Mahlen anfallende Farbe stark mit Farbhäuten durchsetzt. Das Mahlwerk der bisher in Malerwerkstätten benutzten Farbmühlen bestand aus ineinanderlaufenden Stahlkegeln. Mit diesen Stahlkegeln gelingt es jedoch nicht, die Farbhäute völlig zu vermahlen. Es blieb stets ein Rest urgemahlener Häute zurück. Es gelang auch nicht, Mahlwerke mit Mahlsteinen, wie sie in den Farbenfabriken benutzt werden, für Malerwerkstätten zu verwenden, weil der allgemein als Werkstoff für die Mahlsteine benutzte Granit oder auch Stahlplatten zu glatt für die Farbhäute waren, die daher nicht erfaßt und nicht zerkleinert wurden.Unlike in paint factories, that in painting workshops is for grinding accruing color strongly interspersed with color skins. The grinder previously used in painting workshops The paint mills used consisted of steel cones running one inside the other. With these steel cones However, it is not possible to completely grind the colored skins. There was always something left over of previously ground hides. It also did not work, like grinders with millstones they are used in paint factories to use for painting workshops because the granite or steel plates generally used as a material for the millstones were too smooth for the colored skins, which were therefore not grasped and not comminuted.

Erfindungsgemäß können nun für Farbmühlen Mahlsteine verwendet werden, wenn diese aus einem in bestimmter Weise zusammengesetzten griffigen Werkstoff bestehen. Der Mahlvorgang mit derartigen Mahlsteinen geht bedeutend schneller vor sich als mit den bekannten Mahlsteinen, und das Mahlgut einschließlich der Farbhäute wird gleichmäßig fein gemahlen, ohne daß merkliche Verunreinigungen oder urgemahlene Rückstände bleiben.According to the invention, grinding stones can now be used for paint mills, if these consist of a non-slip material composed in a certain way. The grinding process with such grinding stones is much faster than with the well-known millstones, and the grist including the colored skins will evenly finely ground without noticeable impurities or pre-ground Residues remain.

Die vorzugsweise als kreisrunde Scheiben ausgebildeten und mit ihren Kreisflächen aufeinander arbeitenden Mahlsteine bestehen erfindungsgemäß aus 80 bis 900/o Edelkorundkorn 80, Rest Bindefritten. Die Grundstoffe werden gemischt, in eine Form gepreßt und nach Vortrocknung einen Tag bei etwa 1350° C gebrannt. Ausführungsbeispiel 800/o Edelkorundkorn 80, 40/o Quarzmehl 00, 60/o Feldspat, 40/o Glasmehl »G«, 30/o Ton, 30/o Kaolinweiß werden gemischt und unter einem Druck von 150 kg/cm3 in die Form gepreßt. Nach ausreichender Lufttrocknung werden die Steine aus der Form genommen und 24 Stunden bei 1350° C gebrannt.According to the invention, the grinding stones, which are preferably designed as circular disks and work on one another with their circular surfaces, consist of 80 to 900 / o high-grade corundum grain 80, the remainder being bonded frits. The raw materials are mixed, pressed into a mold and, after pre-drying, fired for one day at around 1350 ° C. Embodiment 800 / o high-grade corundum grain 80, 40 / o quartz flour 00, 60 / o feldspar, 40 / o glass flour »G«, 30 / o tone, 30 / o kaolin white are mixed and pressed into the mold under a pressure of 150 kg / cm3. After sufficient air drying, the stones are removed from the mold and fired at 1350 ° C for 24 hours.

Die Steine enthalten auf den, einander zugekehrten Arbeitsseiten vorzugsweise an sich bekannte radiale Ausnehmungen, welche sich über mehr als die Hälfte des Radius erstrecken und gegen den Umfang zu geringer werden.The stones preferably contain on the working sides facing one another known radial recesses, which extend over more than half of the Extend the radius and decrease towards the circumference.
