  • two-shaft compulsory mixers for mixing of the raw materials used. Because in these applications the requirements for the mix quality are relatively high, the mixing usually takes place in so-called batch mixers, where certain amounts of starting materials be mixed together until a mixture of substances with the desired mixing quality. Then will the mixer empties and stands for mixing one other specific amount of substance (batch) available.

Procédé selon la revendication 26, la synchronisation des arbres (3a, 3b) étant réalisée de manière à ce que le premier arbre est étant celui (3a) dont la direction de refoulement (X1) lors de sa rotation normale (D1) est à l'opposée de la direction axiale (Y1) en laquelle on progresse lorsqu'on observe au cours de cette rotation le passage successif à travers le plan horizontal contenant les axes des deux arbres, de deux pales (4) appartenant à deux plans centraux de mixage voisins de cet arbre (3a).
  28. Procédé selon la revendication 26, la synchronisation des arbres (3a, 3b) étant réalisée de manière à ce que le premier arbre (3b) est celui dont la direction de refoulement (X2) lors de sa rotation normale (D2) est orientée dans le même sens que la direction axiale (Y2) en laquelle on progresse, lorsqu'on observe au cours de cette rotation le passage successif à travers le plan horizontal contenant les axes des deux arbres, de deux pales (4) appartenant à deux plans centraux de mixage voisins de cet arbre (3b).
