Abstract

Procédé et dispositif permettant le classement granulométrique de produits broyés et dans lesquels le produit broyé dans un broyeur à meules sort du processus de broyage sous l'action d'une force centrifuge et passe par un courant énergique de gaz séparateur s'écoulant linéairement autour du plateau de broyage. Le produit broyé sort du processus de broyage sous l'effet de la pesanteur, puis subit une accélération pour passer, sous l'action d'une force centrifuge, par un courant énergique de gaz séparateur. L'invention est applicable par exemple au classement de fractions granulométriques de minéraux.Method and device for the granulometric classification of ground products and in which the product ground in a grinding wheel leaves the grinding process under the action of a centrifugal force and passes through an energetic stream of separating gas flowing linearly around the grinding tray. The ground product leaves the grinding process under the effect of gravity, then undergoes an acceleration to pass, under the action of a centrifugal force, by an energetic stream of separating gas. The invention is applicable for example to the classification of granulometric fractions of minerals.
