  Verfahren zur Entwässerung eines   Kalz1umsulfatgesteïns   
Die Erfindung bezieht sich auf ein Verfahren zur Entwässerung eines Kalziumsulfatgesteins und besteht darin, dass das gepulverte Gestein in den Abgasstrom einer Verbrennungskraftmaschine gebracht und in einer Mischung von vorzugsweise 1-5 Vol.-% Gestein, bezogen auf das Volumen des Abgases, durch ein langes Rohr in einen Zyklon zur Abscheidung des getrockneten Pulvers geleitet wird. 



   Das Gemisch aus Abgas und pulverisiertem Kalziumsulfatgestein wird also über eine   z. B.   100 m lange Abgasrohrleitung einem Zyklon zugeleitet, welcher das Kalziumsulfatgestein von den Abgasen trennt, so dass diese in die freie Atmosphäre ausströmen können. 



   Der Anteil des zugefügten Kalziumsulfatgesteins beträgt gegenüber den durchströmenden Abgasen   l-S Vol.-%, d. h.   wenn pro Zeiteinheit 100   l   Abgase durch das Rohr strömen, werden   1 - 5 I   pulverisiertes Kalziumsulfat beigemischt. 



   Auf diese Weise entsteht eine gleichmässige Entziehung des Kristallwassers mit einem sehr niedrigen Aufwand an benötigter Wärme an Kcal/kg pulverisiertem Kalziumsulfat. 



   Die Verbrennungskraftmaschine, welche die Abgase für das erfindungsgemässe Verfahren liefert, kann in zweckmässiger Weise zum Antrieb einer Mühle zur Mahlung des Kalziumsulfatgesteines verwendet werden.

  Method of draining a calcium sulphate rock
The invention relates to a method for dewatering calcium sulfate rock and consists in that the powdered rock is brought into the exhaust gas flow of an internal combustion engine and in a mixture of preferably 1-5% by volume of rock, based on the volume of the exhaust gas, through a long Tube is passed into a cyclone to separate the dried powder.



   The mixture of exhaust gas and pulverized calcium sulfate rock is therefore via a z. B. 100 m long exhaust pipe fed to a cyclone, which separates the calcium sulfate rock from the exhaust gases so that they can flow out into the open atmosphere.



   The proportion of calcium sulphate rock added to the exhaust gases flowing through is 1-S% by volume, i.e. H. If 100 l of exhaust gases flow through the pipe per unit of time, 1 - 5 l of powdered calcium sulfate are added.



   In this way, the water of crystallization is evenly removed with a very low expenditure of required heat of Kcal / kg pulverized calcium sulfate.



   The internal combustion engine which supplies the exhaust gases for the method according to the invention can be used in an expedient manner to drive a mill for grinding the calcium sulfate rock.
