Abstract
L'invention concerne un procédé et un appareil permettant de broyer une substance particulaire, telle que des matières premières de ciment, du ciment non broyé ou analogues, dans un broyeur à cylindres (1), lequel procédé consiste à soumettre ladite substance à une force de pression dans une zone (13) située entre des surfaces tournantes opposées où la substance est dirigée vers la zone de broyage au moyen d'une barre de chariotage (11). Le procédé de l'invention est caractérisé en ce que la substance placée dans la barre de chariotage (11) est accélérée sous l'action de la gravité jusqu'à une vitesse recherchée sans admixtion importante d'air, l'appareil de l'invention étant caractérisé par le fait que la barre de chariotage est en configuration sensiblement verticale, avec une section transversale réduite vers le bas, la diminution de la circonférence transversale de la barre par unité de hauteur décroissant vers le bas. La configuration de la barre de chariotage décrite a montré, d'une manière surprenante, qu'au-delà d'une hauteur ou d'une chute donnée la substance peut atteindre des vitesses élevées, et ce sans entraîner une admixtion d'air dans la substance. Ainsi, il a été montré que la substance peut atteindre des vitesses proches de la vitesse obtenue dans le cadre d'une chute libre des particules individuelles.
