Abstract

Dans le procédé de pulvérisation de matières polydispersionnelles solides de l'invention, ces dernières subissent une pulvérisation préliminaire afin de produire des particules d'une grosseur de 5 mm. On ajoute ensuite aux matières un gaz transporteur s'écoulant à une vitesse de 20 m/s, afin de produire une suspension de matières solides dans le gaz se déplaçant à faible vitesse, laquelle est ensuite acheminée jusque dans la zone de pulvérisation. On introduit dans cette zone un gaz énergétique tangentiel s'écoulant à un débit equivalent à Mach » 1,0. Dans la zone d'amenée, le rapport entre la pression de freinage du gaz énergétique et la pression statique dans l'axe de l'écoulement turbulent est maintenu à une valeur supérieure à une valeur déterminée par la fonction (I), dans laquelle Kj représente la caractéristique adiabatique du gaz énergétique et 1 < k « 1,667. De plus, la pression statique du gaz énergétique dans la zone d'amenée est maintenue à un niveau inférieur à celui de la phase gazeuse de la suspension se déplaçant à grande vitesse formée dans la zone de pulvérisation à mesure que la suspension à faible vitesse est accélérée par le flux supersonique de gaz énergétique. Autour de la périphérie de la zone de pulvérisation sont créées des zones d'agitation, dans chacune desquelles la pression fluctue dans une plage de ±(1...100)Pa par rapport à la pression régnant dans la zone de pulvérisation, et avec une fréquence de fluctuation allant jusqu'à 10 kHz. Le procédé de l'invention permet d'obtenir une surface spécifique de la matière pulvérisée et calibrée comprise entre 8000 et 12,000 cm2/g, en fonction de sa structure, avec une granulométrie moyenne dans le produit fini d'environ 3 $gm(m).
