Description

Die Suspension wird bisher in einem separaten Mischer mit hoher Drehzahl hergestellt, von dort in einen Mischer (Teller-, Doppelwellenmischer, etc.) zugegeben und mit Sand und Kies gemischt.The Suspension is currently in a separate mixer at high speed from there into a mixer (plate, double-shaft mixer, etc.) were added and mixed with sand and gravel.

Das Mischen von Suspension mit Sand und Kies in einem herkömmlichen Mischer ist praktisch nicht möglich. Zum Einen kann die Suspension nicht vorgemischt werden und zum Andern steigt bei der Zugabe von Sand, Kies, Zement, Wasser und Zusatzmittel die Stromaufnahme um ca. das 5–6-fache an.The Mix suspension with sand and gravel in a conventional Mixer is practically impossible. For one, the suspension can not be premixed and to change increases with the addition of sand, gravel, cement, water and additives the power consumption by about 5-6 times.

Die Aufgabe besteht darin, ein Verfahren zu entwickeln in dem die Suspension in einem KKM-Mischer (Konusmischer) vorgemischt und danach Kies und Sand zugegeben wird.The Task is to develop a method in which the suspension premixed in a KKM mixer (cone mixer) and then gravel and sand is added.

Zum Erreichen dieses Zieles gibt es drei Möglichkeiten:

  • a) Das innere Rührwerk des KKM-Mischers mit entsprechender Drehzahl und Drehrichtung auf die erforderliche Geschwindigkeit zu steigern. Das äußere Rührwerk wird an die erforderliche Geschwindigkeit angepaßt. Das Material (Suspension) wird zugegeben und vorgemischt.
  • b) Eine Vorrichtung zum Einfahren in den Mischer (in den unteren Bereich); das Rührwerk kann mit entsprechender Drehzahl betrieben werden, das innere Rührwerk läuft während des Mischvorgangs mit der erforderlichen Geschwindigkeit mit (es kann sowohl links als auch rechts laufen); das äußere Rührwerk steht.
  • c) Nachdem Mischen der Suspension wird das Rührwerk ausgefahren.
There are three ways to achieve this goal:
  • a) Increase the internal agitator of the KKM mixer with the appropriate speed and direction of rotation to the required speed. The outer agitator is adapted to the required speed. The material (suspension) is added and premixed.
  • b) A device for entering the mixer (in the lower area); the agitator can be operated at the appropriate speed, the inner agitator runs at the required speed during the mixing process (it can run both left and right); the outer agitator stands.
  • c) After mixing the suspension, the stirrer is extended.

Danach wird dann Kies und Sand zugegeben und der Mischvorgang kann erfolgen.After that then gravel and sand are added and the mixing process can take place.
