Abstract

La présente invention concerne un mélangeur pour silo caractérisé en ce qu'une plaque de guidage d'introduction de forme prédéterminée, servant à réguler un flux de particules pulvérisées dans un cylindre intérieur monté de manière appropriée dans le silo, et permettant l'introduction aisée des particules pulvérisées dans ce cylindre intérieur, est disposée sur la partie d'une surface circonférentielle intérieure de la paroi de cylindre intérieur se trouvant au voisinage d'un orifice d'introduction ménagé dans une paroi de cylindre interne en vue de l'introduction des particules pulvérisées dans ce dernier. Grâce à cet agencement, seulement une quantité prédéterminée des particules pulvérisées à l'extérieur du cylindre intérieur sont introduites par l'orifice d'introduction dans ce dernier selon la vitesse d'écoulement des particules pulvérisées dans le cylindre intérieur. Lorsque des orifices d'introduction auxiliaires non pourvus de plaques de guidage d'introduction sont formés dans les parties de la paroi de cylindre intérieur situées au-dessus et au-dessous de l'orifice d'introduction précité, une quantité prédéterminée de particules pulvérisées à l'extérieur du cylindre intérieur peuvent être introduites et mélangées dans le cylindre intérieur, en sens vertical et horizontal dans le silo. Il est ainsi possible de mélanger non seulement des pellets de résine d'une granulométrie de plusieurs millimètres mais également de la poudre fine d'une granulométrie de l'ordre du micron, qui jusqu'à présent étaient susceptibles de provoquer un voûtage et un engorgement.
