Dispositif pour granuler des matières en fusion.
@ Il est connu d'amener des matières en fusion, particuliè- rement des métaux, à la forme granuleuse en dirigeant un jet de la matière en fusion, avec admission d'eau, sur une roue en bois mise en rotation. Pour obtenir une meilleure répartition de la masse en fusion, il est utile dans ce cas de munir la roue en bois de rainures fraisées. On a constaté cependant que la roue en bois subit ainsi une usure relativement forte et que les explosions, devenant de plus en plus forte avec l'augmentation de l'usure, entraînent un endommagement tellement fort de la roue que celle-ci doit être remplacée.
Or, il a été trouvé suivant la présente invention qu'on peut considérablement diminuer ces difficultés rencontrées dans la granulation des matières en fusion lorsqu'on dirige la masse en fusion, avec admission d'un liquide, sur une roue ou un rouleau ou.l'on a fixé une couronne dentée subdivisée en segments. Lorsque certaines dents sont devenues inutilisables par suite de l'usure, on peut simplement remplacer le segment denté en cause, sans démonter la roue. Un segment peut comprendre une ou plusieurs dents.
Le dispositif peut être constitué, par exemple, par un cylindre en tôle, fermé aux deux extrémités par deux disques pleins, traversés par l'arbre de commande. Sur ce cylindre ou rouleau sont fixés, à des distances déterminées, des tenons ou languettes à rainures en forme de queue d'aronde, sur lesquels sont glissés les segments dentés munis de rainures. Les segments dentés peuvent être encore subdivisés aussi dans le sens de la longueur du rouleau.
Comme matériau pour les segments dentés on peut utiliser, par exemple, de la masse de bois comprimée ou de la masse de bois coulée. On peut employer aussi du bois naturel en choisissant alors la direction des fibres de manière à obtenir le maximum de résis- tance.
REVENDICATIONS ---------------------------
1.- Dispositif pour granuler des matières en fusion, en particulier des métaux, en les dirigeant sur une roue ou un rouleau, avec admission de liquides, caractérisé en ce qu'une couronne dentée, subdivisée en segments interchangeables, est disposée sur le granulateur en forme de roue ou de rouleau.

Device for granulating molten materials.
@ It is known to bring molten materials, particularly metals, to a granular form by directing a jet of the molten material, with water inlet, on a rotating wooden wheel. To obtain a better distribution of the molten mass, it is useful in this case to provide the wooden wheel with milled grooves. It has been found, however, that the wooden wheel thus undergoes relatively strong wear and that the explosions, becoming more and more severe with the increase in wear, cause such severe damage to the wheel that it must be replaced. .
Now, it has been found according to the present invention that these difficulties encountered in the granulation of molten materials can be considerably reduced when the molten mass is directed, with admission of a liquid, onto a wheel or a roller or. a toothed crown subdivided into segments was fixed. When certain teeth have become unusable as a result of wear, one can simply replace the toothed segment in question, without removing the wheel. A segment can include one or more teeth.
The device can be constituted, for example, by a sheet metal cylinder, closed at both ends by two solid discs, through which the control shaft passes. On this cylinder or roller are fixed, at determined distances, tenons or tongues with grooves in the form of a dovetail, on which are slipped the toothed segments provided with grooves. The toothed segments can be further subdivided also along the length of the roller.
As material for the toothed segments it is possible to use, for example, compressed wood mass or cast wood mass. Natural wood can also be used, then choosing the direction of the fibers so as to obtain the maximum resistance.
CLAIMS ---------------------------
1.- Device for granulating molten materials, in particular metals, by directing them on a wheel or roller, with admission of liquids, characterized in that a toothed ring, subdivided into interchangeable segments, is arranged on the granulator wheel or roller shape.
