Abstract

L'invention concerne un dispositif électrique de broyage de poudre doté d'un cylindre de matériau remplaçable et son procédé de broyage de poudre. Le dispositif de broyage de poudre comprend une source d'alimentation (50), une machine d'entraînement dotée d'une fonction d'inversion et de desserrage, et un ensemble cylindre de matériau. La source d'alimentation (50) est reliée à la machine d'entraînement ; l'ensemble cylindre de matériau comprend un corps de cylindre de matériau (20), un manchon de broyage (26), une tête de broyage (27), et une base fixe (29) ; le corps de cylindre de matériau (20) est relié de manière fixe à la tête de broyage (27) ; la machine d'entraînement est pourvue d'un arbre de sortie ; l'arbre de sortie est relié au corps de cylindre de matériau (20) au moyen d'une structure de liaison ; le manchon de broyage (26) est relié à la base fixe (29) ; la machine d'entraînement comprend un boîtier ; une fente d'insertion est formée sur la paroi latérale interne du boîtier ; une colonne convexe (294) est disposée sur la base fixe (29) et est insérée dans la fente d'insertion ; la tête de broyage (27) est incorporée dans le manchon de broyage (26). Lorsqu'un courant de sortie de la machine d'entraînement est supérieur à une valeur définie, la machine d'entraînement entraîne la tête de broyage à tourner en sens inverse ; lorsque le courant de sortie de la machine d'entraînement n'est pas supérieur à la valeur définie, la machine d'entraînement entraîne la tête de broyage à tourner vers l'avant de façon à réaliser la fonction d'inversion et de desserrage de la machine d'entraînement. Différents manchons et têtes de broyage sont utilisés pour meuler une variété de matériaux, une rotation à double sens est possible, et le taux d'endommagement du dispositif de broyage de poudre est réduit.
