Abstract

Verfahren zur Herstellung fließfähiger Suspensionen mit definierter Konsistenz durch Zusetzen reiner Flüssig­ phase zu fließfähigen Rohsuspensionen unbekannter Kon­ sistenz mit geringem apparativen und regeltechnischen Aufwand, unter Nutzung technologisch vorhandener Größen als Maßgrößen zur Regelung und ohne gesonderte Be­ stimmung der Rohsuspension. Gemäß dem Verfahren fließt eine definierte Menge Rohsuspension aus einem Behälter (1) durch ein vertikal angeordnetes Auslaufrohr (2) zeitlich so überlagert mit einem konstanten Flüssig­ phasenstrom in einen Auffangbehälter, daß das gewünschte Gemisch entsteht. Alternativ fließt die Rohsuspension unbekannter Konsistenz in einer bestimmten Auslaufzeit aus dem Behälter (1) durch das vertikal angeordnete Auslaufrohr (2) in den Auffangbehälter (3), wobei die Flüssigphase in Abhängigkeit eines, der Auslaufzeit zugeordnete Standardvolumens VS, entstehenden Diffe­ renzvolumens ΔV im Auffangbehälter (3) zugeführt wird. Process for the production of flowable suspensions with a defined consistency by adding pure liquid phase to flowable raw suspensions of unknown consistency with little outlay in terms of equipment and control technology, using technologically available parameters as control parameters and without separate determination of the raw suspension. According to the method, a defined amount of raw suspension flows from a container (1) through a vertically arranged outlet pipe (2) overlaid in time with a constant liquid phase flow into a collecting container that the desired mixture is formed. Alternatively, the raw suspension of unknown consistency flows from the container (1) through the vertically arranged discharge pipe (2) into the collecting container (3) in a certain discharge time, the liquid phase depending on a standard volume V S associated with the discharge time, resulting difference volume ΔV im Collection container (3) is supplied.
