Description

Verfahren zum kolloidalen Vermahlen Zusatz zum Patent 649 999 Nach dem Verfahren des Hauptpatents 649 999 können Drogen auf trockenem Wege bis zu ihrer kolloidalen Grenze zerkleinert werden, wobei der Aufschluß der wirksamen Bestandteile, d. h. die Hochverfeinerung, in einer langsam laufenden Kugelmühle vorgenommen wird, welche gleichzeitig mit Drogen, Stahlsand und Stahlkugeln beschickt wird. Von diesen Mühlen können mehrere hintereinandergeschaltet werden. Die Austragung der vermahlenen Stoffe kann durch Luftstrom erfolgen.Process for colloidal grinding Addition to patent 649 999 Nach The process of the main patent 649 999 can dry up their drugs colloidal border are comminuted, whereby the digestion of the active ingredients, d. H. the high refinement is carried out in a slow-running ball mill, which is loaded with drugs, steel sand and steel balls at the same time. Of these Several mills can be connected in series. Discharge of the ground Substances can be made by air flow.

Es hat sich bei angestellten Versuchen gezeigt, daß die reibende, quetschende, besonders aber die schneidende Wirkung der zackigen Stahlkörper (Stahlsand) des in dem Mahlgut eingebetteten Stahlsandes und der Stahlkugeln eine derart große ist, daß nicht nur pflanzliche Stoffe (Drogen), sondern auch Metalle, Mineralien, Pflanzen, Knochen, Leder usw. einer kolloidalen Zerkleinerung unterworfen werden können. Die zu zerkleinernden Stoffe, die zuerst einer Vorzerkleinerung unterworfen sein können, -werden wie bei dem Verfahren nach dem Hauptpatent in einer oder mehreren langsam umlaufenden Mühlen, die hintereinandergeschaltet sind, mit zackigen Stahlkörpern (Stahlsand) und Stahlkugeln gemischt. Das zerkleinerte Mahlgut wird zweckmäßig durch Luftstrom ausgetragen.It has been shown in experiments that the abrasive, squeezing, but especially the cutting effect of the jagged steel body (steel sand) of the steel sand embedded in the grist and the steel balls are so large is that not only plant substances (drugs), but also metals, minerals, Plants, bones, leather, etc. are subjected to colloidal comminution can. The materials to be shredded, which are first subjected to pre-shredding can be, -will as in the process according to the main patent in one or more slowly rotating mills, which are connected in series, with jagged steel bodies (Steel sand) and steel balls mixed. The crushed grist is expediently through Air flow discharged.

Es ist zwar schon bekannt, durch Mischung von größeren und kleineren Stahlmählkörpern und durch Steigerung der Feinheit von Stahlmahlkörpern die Feinheit des Gutes zu erhöhen. Indessen -wurde bisher kein Stahlsand in Mischung mit Stahlkugeln verwendet. Ebenso ist es in der Zerkleinerungstechnik an sich bekannt, mehrere Mahltrommeln hintereinander anzuordnen und die gefeinten Stoffe mit Luftstrom auszutragen. Durch die schneidende; reibende; quetschende Wirkung des zackigen Stahlsandes und der Stahlkugeln sowie - durch den freiem nis, wie zahlreiche Versuche gezeigt haben;"" erzielt. Ein besonderes Gewicht wird bei diesem Verfahren auf die Wirtschaftlichkeit gelegt; es besteht ein geringer Verschleiß in den langsam laufenden Mühlen, Einfaehheit des Arbeitsverfahrens, Einfachheit und Billigkeit der Mühlen. Der Kraftaufwand ist gering. Dies sind Beweise für die Wirtschaftlichkeit des Erfindungsgegenstandes.It is already known to increase the fineness of the material by mixing larger and smaller steel grinding bodies and by increasing the fineness of steel grinding bodies. However, no steel sand mixed with steel balls has been used so far. It is also known per se in comminution technology to arrange several grinding drums one behind the other and to discharge the fine substances with an air stream. Through the cutting; rubbing; crushing effect of the jagged steel sand and steel balls as well as - by the free one nis, as numerous experiments have shown; "" achieved. Particular emphasis is placed on economic efficiency in this process; there is little wear and tear in the slow-running mills, simplicity of the working process, simplicity and cheapness of the mills. The effort required is low. This is evidence of the economic viability of the subject matter of the invention.
