  • TWO-SHAFT MIXER USE OF THE TWO-SHAFT MIXER AND METHOD FOR OPERATING A TWO-SHAFT MIXER
  • the invention relates to a two-shaft compulsory mixer, a use of the two-shaft compulsory mixer and a method for operating a two-shaft compulsory mixer in accordance with the preambles of the independent claims.
  • Two-shaft compulsory mixers are preferably used where medium to large quantities of powdery and / or granular mixes have to be mixed together dry or with the addition of liquid additives (binders).
  • two-shaft compulsory mixers are preferably used to mix the starting materials. Since the requirements for the mixing quality are relatively high in these applications, the mixing is usually carried out in so-called batch mixers, in which certain amounts of starting materials are mixed with one another until a mixture of substances having the desired mixing quality is obtained. The mixer is then emptied and is available for mixing another specific quantity of substance (batch).
  • the starting materials can also be mixed with one another using so-called continuous mixers, which are normally built longer than batch mixers, ie generally have more central mixing levels than these.

  • Mixing tools which form center-mixing planes are considered here exclusively as mixing tools which do not adjoin the end faces of the mixing trough for stripping mixed material from the same or for causing a flow and reversal of the mixed material in the wall area.
  • the mixing tools according to the definition used here are thus located axially between these tools arranged in the end wall area of the mixing trough.
  • center mixing planes exclusively refers to those mixing planes that lie between the planes formed by the reversing or stripping tools.
  • the mixing tools are arranged around the axes of rotation of the mixer shafts in such a way that they radially in different directions extend.

Abstract

L'invention concerne un malaxeur à mélange forcé à deux arbres (1), dont les outils de malaxage (4) sont disposés sur deux arbres (3a, 3b) de malaxage parallèles et synchronisés de façon telle que ces outils de malaxage (4), à chaque rotation des arbres (3a, 3b), traversent de bas en haut le plan horizontal existant entre les deux arbres (3a, 3b), et ce, axialement et successivement, lesdits outils étant contigus dans le sens axial par paire. Lors du passage dans ladite zone entre les arbres (3a, 3b) de malaxage, les outils de malaxage disposés par paires forment ainsi des complexes (9) pratiquement cohérents, qui se déplacent verticalement de bas en haut entre les deux arbres (3a, 3b), ce qui se traduit par une sensible diminution de la durée de malaxage pour une qualité de mélange déterminée, comparativement à des malaxeurs à mélange forcé à deux arbres classiques et dotés d'un même nombre de plans de malaxage médians (5a-5h).
