A method and a mill (1) or crushing station (A) for crushing rubble, wherein the crushed material fills the mill discharging hopper (9) for a height (H1) which is higher than the height (H) of a hopper discharging opening (11) so that a continuous material plug (6) is formed which closes said discharging opening (11). The discharging means (2; 17) can be either integrated into the mill discharging hopper (9) or form a separated discharging device (2) which is associated to the mill (1). In operation the plug (6) is continuously removed from the plug bottom and fed to the plug top so that said continuous plug prevents the formation and exhausting of dust. The known dust separation chambers are thus superfluous.
Procédé et broyeur (1) ou station de concassage (A) permettant de broyer des gravats, lesdits gravats emplissant la trémie (9) d'évacuation du broyeur jusqu'à une hauteur (H1) supérieure à la hauteur (H) d'une ouverture d'évacuation (11) de trémie, si bien qu'il en résulte un flux (6) continu de matériau qui ferme ladite ouverture d'évacuation (11). Le dispositif d'évacuation (2, 17) peut être soit intégré à la trémie (9) d'évacuation du broyeur, soit former un dispositif d'évacuation séparé (2) associé au broyeur (1). Lors du fonctionnement, le flux (6) est continuellement évacué du plancher de flux et envoyé dans la partie supérieure du flux si bien que ce flux continu empêche la formation et l'échappement de poussière. Les chambres de séparation de poussière des dispositifs classiques sont donc superflues.
