Abstract (en)

The method involves using a dosing device to supply pourable material to a mixing area (9) of a mixing chamber (5), where it is mixed with fluid before supply from a pump (11). The dosing device and a mixing device (7) in the mixing chamber are separately operated. The pourable material is supplied perpendicular to the feed device in the mixing chamber in a front or transfer area of the mixing chamber in front of the mixing area. At least part of the mixing fluid is supplied to the front area to form a sump area (16). The dosed dry material is fed or scattered in the sump area. The front area, sump area or edge area (17) between the sump area and the mixing area is monitored using a probe (15), a sensor or a filling level measuring device (15a), to control the supply of the dosed material or the fluid, so that when the pumped feed quantity, and with it the quantity of material in the monitored area, is reduced or increased, the supply of dosed materials or fluid is reduced or stopped or increased, as appropriate. An Independent claim is included for a device for implementing the method.

Abstract (de)

Zum Anmachen von abbindendem Material, insbesondere zum Anmachen einer Baustoffmischung kann diese während einer Beförderung in einer Richtung dosiert und in einen Mischbereich 9 einer Mischkammer 5 eingebracht werden, der eine gegenüber der Förderrichtung der Dosiervorrichtung 4 andere Richtung hat, was eine gute Trennung des Dosierbereiches von dem Mischbereich 9 erlaubt. Dabei kann der Übergangsbereich, insbesondere ein durch die Anmachflüssigkeit gebildeter Einsumpfbereich 16, in welchen das dosierte Material eingebracht wird, und/oder eine Grenzschicht zwischen diesem Einsumpfbereich 16 und dem eigentlichen Mischbereich 9 mit einer oder mehreren Sonden 15 oder dergleichen Meßvorrichtungen 15a überwacht werden, so daß bei einer zu starken Abnahme der Füllung in dem Mischbereich 9 die Zufuhr des Materiales und der Anmachflüssigkeit vergrößert und bei einer zu starken Zunahme vermindert werden können. Dies ermöglicht einen kontinuierlichen Betrieb mit dennoch wechselnden Abnahmemengen an einer Förderpumpe 11 oder auch einen chargenweisen Betrieb, da sich der Füllungsgrad in der Mischkammer jeweils aufgrund der Sondensteuerung selbsttätig anpaßt beziehungsweise in vorwählbaren und vorbestimmten Grenzen aufrechterhalten läßt. <IMAGE>
