The invention relates to a vertical grinding mill, comprising a closed vertical milling container (1), in which a screw conveyor (2) is arranged so that it can be rotationally driven, conveying grinding bodies (17) to the top. The package of grinding bodies (17) adjusts itself during operation such that the surface (29) thereof is configured to slope radially outward and downward and to end in the region of the bottom edge (18) of an outlet for grinding material (11). Gas is introduced into the milling container (1) above the package of grinding bodies. The gas and grinding material (22) is removed from the milling container (1) via the outlet for grinding material (11).
L'invention concerne une tour de broyage par friction présentant un récipient de broyage vertical fermé (1) dans lequel est agencé, de manière à pouvoir être entraîné en rotation un convoyeur à vis sans fin (2), lequel convoie des corps de broyage (17) vers le haut. Le conditionnement de corps de broyage (17) s'ajuste en fonctionnement de telle manière que sa surface (39) est formée de manière décroissante radialement vers l'extérieur et s'ajuste finalement dans la zone de bord inférieur (18) d'une sortie de matière broyée (11). Du gaz est introduit au-dessus du conditionnement de corps de broyage (17) dans le récipient de broyage (1). Le gaz et la matière broyée (22) sont évacués du récipient de broyage (1) à travers la sortie de matière broyée (11).
