mahlenen Staubsandes darf nicht erhoblich geändert werden und 3. das Verhältnis zwischen den gröberen Sandkornchen nnd der Bindemasse (Ton. Ka ! k und Staubsand zusammen) darf nur wenig wechseln.
Da bei grösseren Sandlagern die Menge des dann enthaltenen Staubsandes vie ! faeh starken Schwankungen unterworfen ist und deshalb bei der unmittelbaren Zumischung von solchem Sand die Bedingungen 1 bis 3 nicht mit hinreichender Sicherheit erfüllt werden könnten, wird bei der gewerblichen Nutzbarmachung dieses Verfahrens der zuzusetzende Sand durch Sieben oder Waschen in die gröberen Anteile und Staubsand getrennt, so dass

werden, welche eine gute Klinkerungsfähiglieit der Masse sicherstellen. Das Verhältnis, in dem grober und feiner Sand getrennt eingeführt werden, ist danach zu beurteilen, dass die Bindesubstanz aus Ton, Kalkhydrat und Staubsand für eine leichte Sinterung sorgt, während der grobe Sand dabei die Standfestigkeit im Feuer sicherstellt.
Ausserdem bat er dafür zu sorgen, dass die Ziegel bei Benutzung als Pflasterklinker nicht glatt werden.
PATENT-ANSPRÜCHE :
EMI2.3
mischung von Tonmasse mit Kalk, dadurch gekennzeichnet, dass feuchter Ton mit soviel gepulvertem Ätzkalk, nötigenfalls unter Zugabe von Sand, innigst gemischt wird. dass nur die zum Pressen erforderliche Feuchtigkeit zurückbleibt.

EMI2.1
ground dust sand must not be significantly changed and 3. the ratio between the coarser grains of sand and the binding compound (clay, chalk and dust sand together) must change only a little.
Since with larger sand deposits the amount of dust sand contained is much! faeh is subject to strong fluctuations and therefore conditions 1 to 3 could not be met with sufficient certainty with the direct admixture of such sand, when this process is used commercially, the sand to be added is separated into the coarser parts and dusty sand by sieving or washing, see above that

which ensure good clinkerability of the mass. The ratio in which coarse and fine sand are introduced separately is to be assessed according to the fact that the binding substance of clay, hydrated lime and dust sand ensures easy sintering, while the coarse sand ensures stability in the fire.
He also asked to ensure that the bricks did not become smooth when used as paving clinker.
PATENT CLAIMS:
EMI2.3
Mixing clay with lime, characterized in that moist clay is mixed very closely with as much powdered quick lime, if necessary with the addition of sand. that only the moisture required for pressing remains.
